                                  RISK FACTORS

     An investment in our common stock is very risky. You should carefully
consider the risks described below, together with all of the other information
in this prospectus, before making an investment decision. If any of the
following risks actually occur, our business, financial condition or results of
operations could be materially adversely affected, the trading price of our
common stock could decline, and you may lose all or part of your investment.

     This prospectus also contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of various factors,
including the risks faced by us described below and elsewhere in this
prospectus.

E.PIPHANY HAS A HISTORY OF LOSSES, EXPECTS LOSSES IN THE FUTURE AND MAY NOT EVER
BECOME PROFITABLE.

     We incurred net losses of $491.8 million for the nine months ended
September 30, 2000, $22.4 million in the year ended December 31, 1999, $10.3
million in the year ended December 31, 1998 and $3.1 million in the year ended
December 31, 1997. We had an accumulated deficit of $527.7 million as of
September 30, 2000, and $35.9 million as of December 31, 1999. We expect to
continue to incur losses before amortization charges for the foreseeable future.
In addition, in connection with the acquisitions of Octane, RightPoint, eClass,
and iLeverage, we will incur significant accounting charges for the amortization
of intangible assets over the three years following these mergers. These losses
will be substantial, and we may not ever become profitable. In addition, we
expect to significantly increase our expenses in the near term, especially
research and development and sales and marketing expenses. Therefore, our
operating results will be harmed if our revenue does not keep pace with our
expected increase in expenses or is not sufficient for us to achieve
profitability. If we do achieve profitability in any period, it cannot be
certain that we will sustain or increase profitability on a quarterly or annual
basis.

OUR LIMITED OPERATING HISTORY AND THE LIMITED OPERATING HISTORY OF THE COMPANIES
WE ACQUIRED, MAKES FINANCIAL FORECASTING AND EVALUATION OF OUR BUSINESS
DIFFICULT.

     Our limited operating history and the limited operating history of the
companies that we acquired makes it difficult to forecast the combined company's
future operating results. We were founded in November 1996 and began developing
products in 1997. Our revenue and income potential is unproven. We received our
first revenues from licensing our software and performing related services in
early 1998. Since neither we nor the companies we acquired have a long history
upon which to base forecasts of future operating results, any predictions about
our future revenues and expenses may not be as accurate as they would be if
E.piphany and the other companies we acquired had a longer business history.

VARIATIONS IN QUARTERLY OPERATING RESULTS DUE TO SUCH FACTORS AS CHANGES IN
DEMAND FOR OUR PRODUCTS AND CHANGES IN OUR MIX OF REVENUES MAY CAUSE OUR STOCK
PRICE TO DECLINE.

     We expect our quarterly operating results to fluctuate. We therefore
believe that quarter-to-quarter comparisons of our operating results may not be
a good indication of our future performance, and you should not rely on them to
predict our future performance or the future performance of our stock price. Our
short-term expense levels are relatively fixed and are based on our expectations
of future revenues. As a result, a reduction in revenues in a quarter may harm
our operating results for that quarter. Our quarterly revenues, expenses and
operating results could vary significantly from quarter-to-quarter. If our
operating results in

                                       4
<PAGE>   6

future quarters fall below the expectations of market analysts and investors,
the trading price of our common stock will fall. Factors that may cause our
operating results to fluctuate on a quarterly basis are:

     o    varying size, timing and contractual terms of orders for our products,

     o    our ability to timely complete our service obligations related to
          product sales,

     o    changes in the mix of revenue attributable to higher-margin product
          license revenue as opposed to substantially lower-margin service
          revenue,

     o    customers' decisions to defer orders or implementations, particularly
          large orders or implementations, from one quarter to the next,

     o    changes in demand for our software or for enterprise software and real
          time marketing solutions generally,

     o    announcements or introductions of new products by our competitors,

     o    software defects and other product quality problems,

     o    our ability to integrate acquisitions,

     o    any increase in our need to supplement our professional services
          organization by subcontracting to more expensive consulting
          organizations to help provide implementation, support and training
          services when our own capacity is constrained, and

     o    our ability to hire, train and retain sufficient engineering,
          consulting, training and sales staff.

THE LOSS OF KEY PERSONNEL, OR ANY INABILITY TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL, COULD AFFECT OUR ABILITY TO SUCCESSFULLY GROW OUR BUSINESS.

     Our future success will depend in large part on our ability to hire and
retain a sufficient number of qualified personnel, particularly in sales,
marketing, research and development, service and support. If we are unable to do
so, this inability could affect our ability to grow our business. Competition
for qualified personnel in high technology is intense, particularly in the
Silicon Valley region of Northern California where our principal offices are
located. Our future success also depends upon the continued service of our
executive officers and other key sales, engineering and technical staff. The
loss of the services of our executive officers and other key personnel would
harm our operations. None of our officers or key personnel are bound by an
employment agreement and we do not maintain key person insurance on any of our
employees. We would also be harmed if one or more of our officers or key
employees decided to join a competitor or otherwise compete with us.

     The market price of our common stock has fluctuated substantially since our
initial public offering in September 1999. Consequently, potential employees may
perceive our equity incentives such as stock options as less attractive and
current employees whose options are no longer priced below market value may
choose not to remain employed by us. In that case, our ability to attract or
retain employees will be adversely affected.

IF CUSTOMERS DO NOT CONTRACT DIRECTLY WITH CONSULTING ORGANIZATIONS TO IMPLEMENT
AND SUPPORT OUR PRODUCTS, OUR REVENUES, PROFITABILITY AND MARGINS MAY BE HARMED.

     Our principal focus is providing software solutions rather than services.
As a result, we encourage our customers to purchase consulting, implementation,
maintenance and training services directly from consulting organizations instead
of purchasing these services from us. While we do not receive any fees directly
from these consulting organizations when they contract directly with our
customers, we believe that these consulting organizations increase market
awareness and acceptance of our software solutions and allow us to focus on
software development and licensing. If consulting organizations are unwilling or
unable to provide a sufficient level and quality of services directly to our
customers or if customers are unwilling to contract directly with these
consulting organizations, we may not realize these benefits and our revenues and
profitability may be harmed.

     Further, to the extent that consulting organizations do not provide
consulting, implementation, maintenance and training services directly to our
customers, we need to provide these services to our customers. We provide these
services to our customers either directly through our internal professional
services organization or indirectly through subcontractors we hire to perform
the services on our behalf. Because our margins on service revenues are less
than our margins on license revenues, our overall margins decline when we
provide services to customers. This is particularly true if we hire
subcontractors to perform these services because it costs us more to hire
subcontractors to perform these services than to provide the services ourselves.

IF OUR INTERNAL PROFESSIONAL SERVICES ORGANIZATION DOES NOT PROVIDE
IMPLEMENTATION SERVICES EFFECTIVELY AND ACCORDING TO SCHEDULE, OUR REVENUES AND
PROFITABILITY WOULD BE HARMED.

     Customers that license our products typically require consulting,
implementation, maintenance and training services and obtain them from our
internal professional services, customer support and training organizations,
which employed a staff of 282 as of September 30, 2000, or from outside
consulting organizations. When we provide these services, we generally recognize
revenue from the licensing of our software products as the implementation
services are performed. If our internal professional services organization does
not effectively implement and support our products or if we are unable to expand
our internal professional services organization as needed to meet our customers'
needs, our ability to sell software, and accordingly our revenues, will be
harmed.

     In addition, when we sell licenses together with professional services for
implementation, we generally recognize the revenue from both the license and the
services as we perform the implementation services. Therefore, delays in
providing implementation services will delay our recognition of revenue. If we
are unable to expand our internal professional services organization to keep
pace with sales, we will be required to increase our use of subcontractors to
help meet our implementation and service obligations, which will result in lower
gross margins. In addition, we may be unable to negotiate agreements with
subcontractors to provide a sufficient level and quality of services. If we fail
to retain sufficient subcontractors, our ability to sell software for which
these services are required will be harmed and our revenues will suffer.

OUR SERVICE REVENUES HAVE A SUBSTANTIALLY LOWER MARGIN THAN OUR PRODUCT
REVENUES, AND AN INCREASE IN SERVICE REVENUES RELATIVE TO LICENSE REVENUES COULD
HARM OUR GROSS MARGINS.

     Our service revenues, which includes fees for consulting, implementation,
maintenance and training, were 44% of our revenues for the nine months ended
September 30, 2000, 47% of our revenues for the year ended December 31, 1999 and
34% of our revenues for the year ended December 31, 1998. Our service revenues
have substantially lower gross margins than license revenues. Our cost of
service revenues for the nine months ended September 30, 2000 and the year ended
December 31,1999 was 96% and 102%, respectively, of our service


                                       6
<PAGE>   8

revenues. An increase in the percentage of total revenues represented by
services revenues could adversely affect our overall gross margins.

     Service revenues as a percentage of total revenues and cost of service
revenues as a percentage of total revenues have varied significantly from
quarter to quarter due to our relatively early stage of development. The
relative amount of service revenues as compared to license revenues has varied
based on the volume of software solution orders compared to the volume of
additional user orders. In addition, the amount and profitability of services
can depend in large part on:

     o    the software solution which has been licensed,

     o    the complexity of the customers' information technology environment,

     o    the resources directed by customers to their implementation projects,

     o    the number of users licensed, and

     o    the extent to which outside consulting organizations provide services
          directly to customers.

NEW PRODUCT INTRODUCTIONS AND PRICING STRATEGIES BY OUR COMPETITORS COULD
ADVERSELY AFFECT OUR ABILITY TO SELL OUR PRODUCTS AND COULD RESULT IN PRESSURE
TO PRICE OUR PRODUCTS IN A MANNER THAT REDUCES OUR MARGINS.

     Competitive pressures could prevent us from growing, reduce our market
share or require us to reduce prices on our products and services, any of which
could harm our business.

     We compete principally with vendors of:

     o    enterprise application software, such as Oracle, PeopleSoft, SAP and
          Siebel Systems,

     o    data management and data analysis software tools, such as Broadbase,
          Business Objects, Informatica, and Microstrategy,

     o    marketing campaign management software tools, such as Exchange
          Applications, Prime Response, and Recognition Systems,

     o    software that recommends products to customers in real-time such as
          Net Perceptions, and

     o    electronic customer relationship management software, such as Kana
          Communications, eGain, and Primus Knowledge Solutions.

     Many of these companies have significantly greater financial, technical,
marketing, service and other resources. Many of these companies also have a
larger installed base of users, have been in business longer or have greater
name recognition than we do. Some large companies may attempt to build
capabilities into their products that are similar to the capabilities of our
products. Some of our competitors' products may be more effective than our
products at performing particular functions or be more customized for particular
needs. Even if these functions are more limited than those provided by our
products, our competitors' software products could discourage potential
customers from purchasing our products. For example, our competitors' software
products may incorporate other capabilities,


                                       7
<PAGE>   9


such as recording accounting transactions, customer orders or inventory
management data. A software product that performs these functions, as well as
some of the functions of our software solutions, may be appealing to some
customers because it would reduce the number of different types of software
necessary to effectively run their business. Further, our competitors may be
able to respond more quickly than we can to changes in customer requirements.

     In addition, our products must integrate with software solutions provided
by a number of our existing or potential competitors. These competitors could
alter their products so that our products no longer integrate well with them, or
they could deny or delay access by us to advance software releases that allow us
to timely adapt our products to integrate with their products.

     Our competitors have made and may also continue to make strategic
acquisitions or establish cooperative relationships among themselves or with
other software vendors. This may increase the ability of their products to
address the need for software solutions such as ours, which provide both the
ability to collect data from multiple sources and analyze that data to profile
customer characteristics and preferences. Our competitors may also establish or
strengthen cooperative relationships with our current or future distributors or
other parties with whom we have relationships, thereby limiting our ability to
sell through these channels, reducing promotion of our products and limiting the
number of consultants available to implement our software.

OUR REVENUES MIGHT BE HARMED BY RESISTANCE TO ADOPTION OF E.PIPHANY'S SOFTWARE
BY INFORMATION TECHNOLOGY DEPARTMENTS.

     Some businesses may have already made a substantial investment in other
third party or internally developed software designed to integrate data from
disparate sources and analyze this data or manage marketing campaigns. These
companies may be reluctant to abandon these investments in favor of our
software. In addition, information technology departments of potential customers
may resist purchasing our software solutions for a variety of other reasons,
particularly the potential displacement of their historical role in creating and
running software and concerns that packaged software products are not
sufficiently customizable for their enterprises. If the market for our products
does not grow for any of these reasons, our revenues will be harmed.

IF THE MARKET IN WHICH WE SELL OUR PRODUCTS AND SERVICES DOES NOT GROW AS WE
ANTICIPATE, OUR REVENUES WILL BE REDUCED.

     If the market for software that enables companies to establish, manage,
maintain and continually improve customer relationships by collecting and
analyzing data to design and manage marketing campaigns and customize products
and services and providing timely, consistent, multichannel customer interaction
does not grow as quickly or become as large as we anticipate, our revenues will
be reduced. Our market is still emerging, and our success depends on its growth.
Our potential customers may:

     o    not understand or see the benefits of using these products,

     o    not achieve favorable results using these products,

     o    experience technical difficulty in implementing or using these
          products, or

     o    use alternative methods to solve the same business problems.


                                       8
<PAGE>   10

     In addition, because our products can be used in connection with Internet
commerce and we are currently developing additional Internet commerce solutions,
if the Internet commerce market does not grow as quickly as we anticipate, we
may experience sales, which are lower than our expectations.

IF WE FAIL TO DEVELOP NEW PRODUCTS OR IMPROVE OUR EXISTING PRODUCTS TO MEET OR
ADAPT TO THE CHANGING NEEDS AND STANDARDS OF OUR INDUSTRY, SALES OF OUR PRODUCTS
MAY DECLINE.

     Our future success depends on our ability to address the rapidly changing
needs of our customers and potential customers. We must maintain and improve our
E.piphany E.5 System and develop new products that include new technological
developments, keep pace with products of our competitors and satisfy the
changing requirements of our customers. If we do not, we may not achieve market
acceptance and we may be unable to attract new customers. E.piphany may also
lose existing customers, to whom we seek to sell additional software solutions
and professional services.

     To achieve increased market acceptance of our products, we must, among
other things, continue to:

     o    improve and introduce new software solutions for reporting and
          analysis, distributed database marketing and e-commerce,

     o    improve the effectiveness of our software, particularly in
          implementations involving very large databases and large numbers of
          simultaneous users,

     o    enhance our software's ease of administration,

     o    improve our software's ability to extract data from existing software
          systems, and

     o    adapt to rapidly changing computer operating system and database
          standards and Internet technology.

     We may not be successful in developing and marketing these or other new or
improved products. If we are not successful, we may lose sales to competitors.

     In addition, we have entered into customer contracts, which contain
specific performance goals relating to new product releases or enhancements, and
if we are not able to meet these goals, we may be required to, among other
things, return fees, pay damages and offer discounts.

IF OUR PRODUCTS DO NOT STAY COMPATIBLE WITH CURRENTLY POPULAR SOFTWARE PROGRAMS,
WE MAY LOSE SALES AND REVENUES.

     The E.piphany E.5 System must work with commercially available software
programs that are currently popular. If these software programs do not remain
popular, or we do not update our software to be compatible with newer versions
of these programs, we may lose customers.

     In order to operate the E.piphany E.5 System, the system must be installed
on both a computer server running the Microsoft Windows NT or Windows 2000
computer operating systems and a computer server running database software from
Microsoft or Oracle. E.piphany is currently modifying its respective software to
also operate on UNIX operating systems and IBM DB2 databases. If we fail to
successfully complete these modifications in a timely manner, we may lose sales
and revenues. In addition, users access the E.piphany


                                       9
<PAGE>   11

E.5 System through standard Internet browsers such as Microsoft Internet
Explorer. If we fail to obtain access to developer versions of these software
products, we may be unable to build and enhance our products on schedule.

     After installation, the E.piphany E.5 System collects and analyzes data to
profile customers' characteristics and preferences. This data may be stored in a
variety of our customers' existing software systems, including leading systems
from Oracle, PeopleSoft, Siebel Systems, SAP and Vantive, running on a variety
of computer operating systems. If we fail to enhance our software to collect
data from new versions of these products, we may lose potential customers. If we
lose customers, our revenues and profitability may be harmed.

IF DATABASE ACCESS BECOMES STANDARDIZED, DEMAND FOR OUR PRODUCTS WILL BE
REDUCED.

     Our products are useful for integrating data from a variety of disparate
data sources. Adoption of uniform, industry-wide standards across various
database and analytic software programs could minimize the importance of the
data integration capabilities of our products. This, in turn, could adversely
affect the competitiveness and market acceptance of our products. Also, a single
competitor in the market for database and analytic software programs or Internet
relationship management may become dominant, even if there is no formal
industry-wide standard. If large numbers of our customers adopt a single
standard, this would similarly reduce demand for our product. If E.piphany loses
customers because of the adoption of standards, we may have lower revenues and
profitability.

OUR PRODUCTS HAVE LONG SALES CYCLES WHICH MAKES IT DIFFICULT TO PLAN EXPENSES
AND FORECAST RESULTS.

     It takes us between three and six months to complete the majority of our
sales, but it can take us up to one year or longer. It is therefore difficult to
predict the quarter in which a particular sale will occur and to plan
expenditures accordingly. The period between initial contact with a potential
customer and their purchase of products and services is relatively long due to
several factors, including:

     o    the complex nature of our products,

     o    our need to educate potential customers about the uses and benefits of
          our products,

     o    the purchase of our products requires a significant investment of
          resources by a customer,

     o    our customers have budget cycles which affect the timing of purchases,

     o    many of our customers require competitive evaluation and internal
          approval before purchasing our products,

     o    potential customers may delay purchases due to announcements or
          planned introductions of new products by E.piphany or its competitors,
          and

     o    many of our customers are large organizations, which may require a
          long time to make decisions.

     The delay or failure to complete sales in a particular quarter could reduce
our revenues in that quarter, as well as subsequent quarters over which revenues
for the sale would likely be recognized. If our sales cycle unexpectedly
lengthens in general or for one or more large orders, it would adversely affect
the timing of our revenues. If we were to experience a delay of several weeks on
a large order, it could harm our ability to meet our forecasts for a given
quarter.

IF WE FAIL TO ESTABLISH, MAINTAIN OR EXPAND OUR RELATIONSHIPS WITH THIRD
PARTIES, OUR ABILITY TO GROW REVENUES COULD BE HARMED.

     In order to grow our business, we must generate, retain and strengthen
relationships with third parties. To date, we have established relationships
with several companies, including consulting organizations and system
integrators that implement our software, including Ernst & Young, KPMG and
PricewaterhouseCoopers; resellers, including Acxiom, Harte-Hanks and Pivotal;
and application service providers that provide access to our software to their
customers over the Internet, including Corio and Interrelate. If the third
parties with whom we have relationships do not provide sufficient, high-quality
service or integrate and support our software correctly, our revenues may be
harmed. In addition, the third parties with whom we have relationships may offer
products of other companies, including products that compete with our products.
We typically enter into contracts with third parties that generally set out the
nature of our relationships. However, our contracts do not require these third
parties to devote resources to promoting, selling and supporting our products.
Therefore we have little control over these third parties. We cannot assure you
that we can generate and maintain relationships that offset the significant time
and effort that are necessary to develop these relationships.

     We must also effectively take advantage of the resources and expertise of
third parties to help them develop the E.piphany E.5 System. Our agreements with
third parties do not require them to help us develop new software. If we fail to
effectively work with third parties, our ability to increase revenues by
broadening our software solution offerings, particularly in additional specific
industries, will be limited.

IF WE FAIL TO EXPAND OUR DIRECT AND INDIRECT SALES CHANNELS, WE WILL NOT BE ABLE
TO INCREASE REVENUES.

     In order to grow our business, we need to increase market awareness and
sales of our products and services. To achieve this goal, we need to increase
both our direct and indirect sales channels. If we fail to do so, this failure
could harm our ability to increase revenues. We currently receive substantially
all of our revenues from direct sales, but we intend to increase sales through
indirect sales channels in the future. We also need to expand our direct sales
force by hiring additional salespersons and sales management.

     We intend to derive revenues from indirect sales channels by selling our
software through value added resellers. These resellers offer our software
products to their customers together with consulting and implementation services
or integrate our software solutions with other software. We also intend to
increasingly offer our software through application service providers, who
install our software on their own computer servers and charge their customers
for access to that software. We need to expand our indirect sales channels by
entering into additional relationships with these third parties.

     We have not derived a material amount of revenues from international sales
to date, but we expect as part of our strategy to increase international sales
principally through the use of indirect sales channels. We will be even more
dependent on indirect sales channels in the future due to our international
strategy. We also plan to use international direct sales personnel and therefore
must hire additional sales personnel outside the United States. Our ability to
develop and maintain these channels will significantly affect our ability to
penetrate international markets.

WE HAVE GROWN VERY QUICKLY AND IF WE FAIL TO MANAGE OUR GROWTH, OUR ABILITY TO
GENERATE NEW REVENUES AND ACHIEVE PROFITABILITY WOULD BE HARMED.

     We have grown significantly since our inception and will need to grow
quickly in the future. Any failure to manage this growth could impede our
ability to increase revenues and achieve profitability. We have increased our
number of employees from 21 at December 31, 1997 to 849 as of September 30,
2000. Our


                                       11

<PAGE>   13


future expansion could be expensive and strain our management and other
resources. In order to manage growth effectively, we must:

     o    hire, train and integrate new personnel,

     o    integrate people and technologies from acquired companies,

     o    continue to augment our financial and accounting systems,

     o    manage our sales operations, which are in several locations,

     o    expand our facilities, and

     o    if we do not manage our growth effectively, our business could suffer.

IF WE ACQUIRE ADDITIONAL COMPANIES OR TECHNOLOGIES IN THE FUTURE, THEY COULD
PROVE DIFFICULT TO INTEGRATE, DISRUPT OUR BUSINESS, DILUTE STOCKHOLDER VALUE OR
ADVERSELY AFFECT OUR OPERATING RESULTS.

     In addition to the acquisitions that we have already completed, we may
acquire or make investments in other complementary companies, services and
technologies in the future. If we fail to properly evaluate and execute
acquisitions and investments, they may seriously harm our business and
prospects. To successfully complete an acquisition, we must:

     o    properly evaluate the business, personnel and technology of the
          company to be acquired,

     o    accurately forecast the financial impact of the transaction, including
          accounting charges and transaction expenses,

     o    integrate and retain personnel,

     o    combine potentially different corporate cultures,

     o    effectively integrate products and research and development, sales,
          marketing and support operations, and

     o    maintain focused on our day-to-day operations.

     Further, the financial consequences of our acquisitions and investments may
include potentially dilutive issuances of equity securities, one-time
write-offs, amortization expenses related to goodwill and other intangible
assets and the incidence of contingent liabilities.

IF OTHERS CLAIM THAT WE ARE INFRINGING THEIR INTELLECTUAL PROPERTY, WE COULD
INCUR SIGNIFICANT EXPENSES OR BE PREVENTED FROM SELLING OUR PRODUCTS.

     We cannot assure you that others will not claim that we are infringing
their intellectual property rights or that we do not in fact infringe those
intellectual property rights. We have not conducted a search for existing
intellectual property registrations and we may be unaware of intellectual
property rights of others that may cover some of our technology.

     We have been contacted by a company which has asked us to evaluate the need
for a license of several patents that the company holds directed to data
extraction technology. This company has filed litigation alleging infringement
of its patents against several of our competitors. We cannot assure you that the
holder of the patents will not file litigation against us or that we would
prevail in the case of such litigation. In addition, the patent holder has
informed us that it has applications pending in numerous foreign countries. The
patent holder may also have applications on file in the United States covering
related subject matter which are confidential until the patent or patents, if
any, is issued.

     Any litigation regarding intellectual property rights could be costly and
time-consuming and divert the attention of our management and key personnel from
our business operations. The complexity of the technology involved and the
uncertainty of intellectual property litigation increase these risks. Claims of
intellectual property infringement might also require us to enter into costly
royalty or license agreements.

     However, we may not be able to obtain royalty or license agreements on
terms acceptable to us, or at all. We also may be subject to significant damages
or an injunction against use of our products. A successful claim of patent or
other intellectual property infringement against us would have an immediate
material adverse effect on our business and financial condition.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, THIS INABILITY
COULD WEAKEN OUR COMPETITIVE POSITION, REDUCE OUR REVENUES AND INCREASE OUR
COSTS.

     Our success depends in large part on our proprietary technology. We rely on
a combination of patent, copyright, trademark and trade secrets, confidentiality
procedures and licensing arrangements to establish and protect our proprietary
rights. We may be required to spend significant resources to monitor and police
our intellectual property rights. If we fail to successfully enforce our
intellectual property rights, our competitive position may be harmed.


                                       12
<PAGE>   14

     Our pending patent and trademark registration applications may not be
allowed or competitors may successfully challenge the validity or scope of these
registrations. In addition, our patents may not provide a significant
competitive advantage.

     Other software providers could copy or otherwise obtain and use our
products or technology without authorization. They also could develop similar
technology independently which may infringe our proprietary rights. We may not
be able to detect infringement and may lose a competitive position in the market
before it does so. In addition, competitors may design around our technology or
develop competing technologies. The laws of some foreign countries do not
protect proprietary rights to the same extent as do the laws of the United
States.

     In addition, one of the ways in which we charge for our software is based
on the number of users at a particular site that will be permitted to use the
software. Organizations that have a site license for a fixed number of users for
our products could allow unauthorized use of our software by unlicensed users.
Unauthorized use is difficult to detect and, to the extent that our software is
used without authorization, we may lose potential license fees.

PRIVACY AND SECURITY CONCERNS, PARTICULARLY RELATED TO THE USE OF OUR SOFTWARE
ON THE INTERNET, MAY LIMIT THE EFFECTIVENESS OF AND REDUCE THE DEMAND FOR OUR
PRODUCTS.

     The effectiveness of our software products relies on the storage and use of
customer data collected from various sources, including information collected on
Web sites, as well as other data derived from customer registrations, billings,
purchase transactions and surveys. Our collection and use of such data for
customer profiling may raise privacy and security concerns. Our customers
generally have implemented security measures to protect customer data from
disclosure or interception by third parties. However, the security measures may
not be effective against all potential security threats. If a well-publicized
breach of customer data security were to occur, our software products may be
perceived as less desirable, impacting our future sales and profitability.

     In addition, due to privacy concerns, some Internet commentators, consumer
advocates, and governmental or legislative bodies have suggested legislation to
limit the use of customer profiling technologies. The European Union and some
European countries have already adopted some restrictions on the use of customer
profiling data. In addition, Internet users can, if they choose, configure their
Web browsers to limit the collection of user data for customer profiling. Should
many Internet users choose to limit the use of customer profiling technologies,
or if major countries or regions adopt legislation or other restrictions on the
use of customer profiling data, E.piphany's software would be less useful to
customers, and E.piphany's sales and profits could decrease.

OUR PRODUCTS ARE NEW, AND IF THEY CONTAIN DEFECTS, OR OUR SERVICES ARE NOT
PERCEIVED AS HIGH QUALITY, WE COULD LOSE POTENTIAL CUSTOMERS OR BE SUBJECT TO
DAMAGES.

     We began shipping our first products in early 1998. These products are
complex and may contain currently unknown errors, defects or failures,
particularly since they are new and recently released. In the past we have
discovered software errors in some of our products after introduction. We may
not be able to detect and correct errors before releasing our products
commercially. If our commercial products contain errors, we may be required to:

     o    expend significant resources to locate and correct the error,



                                       13
<PAGE>   15

     o    delay introduction of new products or commercial shipment of products,
          or

     o    experience reduced sales and harm to our reputation from dissatisfied
          customers.

     Our customers also may encounter system configuration problems which
require us to spend additional consulting or support resources to resolve these
problems.

     In addition, our customers generally store their data across computer
networks, which are often connected to the Internet. Our software operates
across our customers' computer networks and can, at the customer's option, be
accessed through an Internet connection. Our software contains technology
designed to prevent theft or loss of data. Nevertheless, customers may encounter
security issues with their existing databases installed across networks,
particularly the Internet, or with our software. A security breach involving our
software, or a widely publicized security breach involving the Internet
generally, could harm our sales. A security breach involving our software could
also expose us to claims for damages.

     Because our software products are used for important decision-making
processes and enable our customers to interact with their customers, product
defects may also give rise to product liability claims. Although our license
agreements with customers typically contain provisions designed to limit our
exposure, some courts may not enforce all or part of these limitations. Although
we have not experienced any product liability claims to date, we may encounter
these claims in the future. Product liability claims, whether or not successful,
could:

     o    divert the attention of our management and key personnel from our
          business,

     o    be expensive to defend, and

     o    result in large damage awards.

     Our product liability insurance may not be adequate to cover all of the
expenses resulting from a claim. In addition, if our customers do not find our
services to be of high quality, they may elect to use other training, consulting
and product integration firms rather than contract for our services. If
customers are dissatisfied with our services, we may lose revenues.

WE INTEND TO EXPAND OUR INTERNATIONAL SALES EFFORTS BUT WE DO NOT HAVE
SUBSTANTIAL EXPERIENCE IN INTERNATIONAL MARKETS.

     Although our international sales have been immaterial to date, we intend to
expand our international sales efforts in the future. We have limited experience
in marketing, selling and supporting our products and services abroad. If we are
unable to grow our international operations successfully and in a timely manner,
our business and operating results could be seriously harmed. In addition, doing
business internationally involves greater expense and many additional risks,
particularly:

     o    unexpected changes in regulatory requirements, taxes, trade laws and
          tariffs,

     o    differing intellectual property rights,

     o    differing labor regulations,

     o    unexpected changes in regulatory requirements,


                                       14
<PAGE>   16

     o    changes in a specific country's or region's political or economic
          conditions,

     o    greater difficulty in establishing, staffing and managing foreign
          operations, and

     o    fluctuating exchange rates.

     We plan to expand our international operations in the near future, and this
will require a significant amount of attention from our management and
substantial financial resources. We have begun efforts at international
expansion in Europe and, as of September 30, 2000, had 51 sales and marketing
professionals located in the United Kingdom, Australia, Germany, Canada, Japan,
The Netherlands and France. We are also exploring other regions for future
expansion.

SEASONAL TRENDS IN SALES OF BUSINESS SOFTWARE MAY AFFECT OUR QUARTERLY REVENUES.

     The market for business software has experienced seasonal fluctuations in
demand. The first and third quarters of the year have been typically
characterized by lower levels of revenue growth. We believe that these
fluctuations are caused in part by customer buying patterns, which are
influenced by year-end budgetary pressures and by sales force commission
structures. As our revenues grow, we may experience seasonal fluctuations in our
revenues.


                                       15

WE DO NOT INTEND TO PAY DIVIDENDS, YOU WILL NOT RECEIVE FUNDS WITHOUT SELLING
SHARES AND YOU MAY LOSE THE ENTIRE AMOUNT OF YOUR INVESTMENT.

     We have never declared or paid any cash dividends on our capital stock and
do not intend to pay dividends in the foreseeable future. We intend to invest
our future earnings, if any, to fund our growth. Therefore, you will not receive
any funds without selling your shares. We further cannot assure you that you
will receive a return on your investment when you sell your shares or that you
will not lose the entire amount of your investment.

PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY DELAY OR PREVENT AN
ACQUISITION OF E.PIPHANY.

     Our certificate of incorporation and bylaws contain provisions which could
make it harder for a third party to acquire us without the consent of our board
of directors. For example, if a potential acquiror were to make a hostile bid
for us, the acquiror would not be able to call a special meeting of stockholders
to remove our board of directors or act by written consent without a meeting. In
addition, our board of directors have staggered terms, which makes it difficult
to remove them all at once. The acquiror would also be required to provide
advance notice of its proposal to remove directors at an annual meeting. The
acquiror also will not be able to cumulate votes at a meeting, which will
require the acquiror to hold more shares to gain representation on the board of
directors than if cumulative voting were permitted.

     Our board of directors also has the ability to issue preferred stock which
would significantly dilute the ownership of a hostile acquiror. In addition,
Section 203 of the Delaware General Corporation Law limits business combination
transactions with 15% stockholders that have not been approved by the board of
directors. These provisions and other similar provisions make it more difficult
for a third party to acquire us without negotiation. These provisions may apply
even if the offer may be considered beneficial by some stockholders.

     Our board of directors could choose not to negotiate with an acquiror that
it did not feel was in the strategic interests of our company. If the acquiror
was discouraged from offering to acquire us, or prevented from successfully
completing a hostile acquisition by the antitakeover measures, you could lose
the opportunity to sell your shares at a favorable price.

                                 E.PIPHANY, INC.

     We develop, market and sell the E.piphany E.5 System, an integrated suite
of customer relationship management software solutions that provides
capabilities for the analysis of customer data, the creation of inbound and
outbound marketing campaigns, and the execution of sales and service customer
interactions. Companies can implement the E.piphany E.5 System to collect and
analyze data from their existing software systems, and from third party data
providers, to better understand and proactively and personally interact with
their customers across a variety of channels. Business users within these
companies can use this information to design and execute marketing campaigns as
well as personalize products, services and related interactions. Our
headquarters are located at 1900 South Norfolk Street, Suite 310, San Mateo,
California 94403 and the telephone number is (650) 356-3800.

                                 USE OF PROCEEDS

     Because the shares of our common stock offered hereunder are being offered
by a stockholder of E.piphany, Inc., we will receive no proceeds upon the sale
of such common stock.

                              PLAN OF DISTRIBUTION

     The selling stockholder may, from time to time, sell all or a portion of
the shares as follows:

     o    at prices and at terms then prevailing in the market,

     o    at prices related to the then current market price, or

     o    in negotiated transactions.

     The shares may be sold by the selling stockholder by one or more of the
following methods, or others:

     o    block trades in which the broker or dealer so engaged will attempt to
          sell the shares as agent but may position and resell a portion of the
          block as principal to facilitate the transaction,

     o    purchases by a broker or dealer as principal and resale by the broker
          or dealer for its account pursuant to this prospectus,

     o    on a stock exchange in accordance with the rules of the particular
          exchange,

     o    ordinary brokerage transactions and transactions in which the broker
          solicits purchasers,

     o    privately negotiated transactions, or

     o    a combination of any of these methods of sale.

     In effecting sales, brokers and dealers engaged by the selling stockholder
may arrange for other brokers or dealers to participate. Brokers or dealers may
receive commissions or discounts from the selling stockholder, or, if any
broker-dealer acts as agent for the purchaser of the shares, from the purchaser,
in amounts to be negotiated which are not expected to exceed those customary in
the types of transactions involved. Broker-dealers may agree with the selling
stockholder to sell a specified number of the shares at a stipulated price per
share, and, to the extent the broker-dealer is unable to do so acting as agent
for the selling



                                       17
<PAGE>   19

stockholder, to purchase as principal any unsold shares at the price required to
fulfill the broker-dealer commitment to the selling stockholder. Broker-dealers
who acquire shares as principal may subsequently resell the shares from time to
time in the following transactions:

     o    transactions, which may involve block transactions and sales to and
          through other broker-dealers, in the over-the-counter market or
          otherwise at prices and on terms then prevailing at the time of sale,

     o    in negotiated transactions, or

     o    at prices related to the then-current market price.

     In connection with these resales, the broker-dealer may pay to or receive
from the purchasers of the shares commissions as described above.

     The selling stockholder and any broker-dealers or agents that participate
with the selling stockholder in sales of the shares may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with any
sales. In the event of a sale, any commissions received by the broker-dealers or
agents and any profit on the resale of the shares purchased by them may be
deemed to be underwriting commissions or discounts under the Securities Act. In
addition, Regulation M under the Securities Exchange Act of 1934, as amended,
may apply in connection with the selling stockholder's sales of his shares.

     We have agreed to pay all fees and expenses incident to the registration of
the shares. The selling stockholder will pay all commissions and discounts, if
any, attributable to the sales of the shares. We have agreed to indemnify the
selling stockholder against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act.

     We will file a supplement to this prospectus, if required, upon being
notified by the selling stockholder that any material arrangement has been
entered into for the sale of the shares though a block trade, or as otherwise
may be required.

     The selling stockholder may, in the future, also sell the shares in
accordance with Rule 144 under the Securities Act, rather than pursuant to this
prospectus.

                                     EXPERTS

     The audited financial statements incorporated in this prospectus by
reference from E.piphany, Inc.'s Annual Report on Form 10-K for the fiscal years
ended December 31, 1997, 1998 and 1999 have been audited by Arthur Andersen LLP,
independent public accountants, as indicated in their reports with respect
thereto, which are incorporated herein by reference, and have been so
incorporated in reliance upon the authority of said firm as experts in
accounting and auditing.

                  CHANGE IN OUR INDEPENDENT PUBLIC ACCOUNTANTS

     In July 1998, KPMG LLP resigned as our independent public accountants, as
KPMG LLP became an integrator of our products and purchased our preferred stock.
The former independent accountants' report on our financial statements for the
year ended December 31, 1997 did not contain an adverse opinion, a disclaimer of
opinion or any qualifications or modifications related to uncertainty,
limitation of audit scope or application of accounting principles. The former
independent public accountants' report does not cover any of our financial
statements in this registration statement. KPMG LLP did not issue an audit
opinion on our financial statements for any other period. There were no
disagreements with the former public accountants on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure with respect to our financial statements up through the time of
dismissal that, if not resolved to the former accountants' satisfaction, would
have caused them to make reference to the subject matter of the disagreement in
connection with their report. In September 1998, we retained Arthur Andersen LLP
as our independent public accountants. The decision to retain Arthur Andersen
LLP was approved by resolution of our board of directors. Prior to retaining
Arthur Andersen LLP, we had not consulted with Arthur Andersen LLP regarding
accounting principles.

     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

     Article VII of the Registrant's Amended and Restated Certificate of
Incorporation provides for the indemnification of directors to the fullest
extent permissible under Delaware law.

     Article VI of the Registrant's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the Registrant if such
person acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of the Registrant, and, with respect to any
criminal action or proceeding, the indemnified party had no reason to believe
his or her conduct was unlawful.

     The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
the Registrant's Bylaws, and intends to enter into indemnification agreements
with any new directors and executive officers in the future.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

     The shares of common stock being offered under this prospectus were sold to
Mr. Siboni on July 1, 1998 in connection with our hiring of Mr. Siboni as our
Chief Executive Officer at that time. The shares were offered and sold to Mr.
Siboni in reliance upon the private offering exemption provided by Section 4(2)
of the Securities Act. At the time of the offer and sale, Mr. Siboni was an
accredited investor, had such knowledge and experience in financial and business
matters that he was capable of evaluating the merits and risks of the investment
and was given the opportunity to ask questions and receive answers concerning
the terms and conditions of the offering.

ITEM 9. UNDERTAKINGS

     (a)  The undersigned Registrant hereby undertakes:

          (i)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement.

          (ii) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended (the "Securities Act") each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

          (iii) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                                  RISK FACTORS

     An investment in our common stock is very risky. You should carefully
consider the risks described below, together with all of the other information
in this prospectus, before making an investment decision. If any of the
following risks actually occur, our business, financial condition or results of
operations could be materially adversely affected, the trading price of our
common stock could decline, and you may lose all or part of your investment.

     This prospectus also contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of various factors,
including the risks faced by us described below and elsewhere in this
prospectus.

E.PIPHANY HAS A HISTORY OF LOSSES, EXPECTS LOSSES IN THE FUTURE AND MAY NOT EVER
BECOME PROFITABLE.

     We incurred net losses of $491.8 million for the nine months ended
September 30, 2000, $22.4 million in the year ended December 31, 1999, $10.3
million in the year ended December 31, 1998 and $3.1 million in the year ended
December 31, 1997. We had an accumulated deficit of $527.7 million as of
September 30, 2000, and $35.9 million as of December 31, 1999. We expect to
continue to incur losses before amortization charges for the foreseeable future.
In addition, in connection with the acquisitions of Octane, RightPoint, eClass,
and iLeverage, we will incur significant accounting charges for the amortization
of intangible assets over the three years following these mergers. These losses
will be substantial, and we may not ever become profitable. In addition, we
expect to significantly increase our expenses in the near term, especially
research and development and sales and marketing expenses. Therefore, our
operating results will be harmed if our revenue does not keep pace with our
expected increase in expenses or is not sufficient for us to achieve
profitability. If we do achieve profitability in any period, it cannot be
certain that we will sustain or increase profitability on a quarterly or annual
basis.

OUR LIMITED OPERATING HISTORY AND THE LIMITED OPERATING HISTORY OF THE COMPANIES
WE ACQUIRED, MAKES FINANCIAL FORECASTING AND EVALUATION OF OUR BUSINESS
DIFFICULT.

     Our limited operating history and the limited operating history of the
companies that we acquired makes it difficult to forecast the combined company's
future operating results. We were founded in November 1996 and began developing
products in 1997. Our revenue and income potential is unproven. We received our
first revenues from licensing our software and performing related services in
early 1998. Since neither we nor the companies we acquired have a long history
upon which to base forecasts of future operating results, any predictions about
our future revenues and expenses may not be as accurate as they would be if
E.piphany and the other companies we acquired had a longer business history.

VARIATIONS IN QUARTERLY OPERATING RESULTS DUE TO SUCH FACTORS AS CHANGES IN
DEMAND FOR OUR PRODUCTS AND CHANGES IN OUR MIX OF REVENUES MAY CAUSE OUR STOCK
PRICE TO DECLINE.

     We expect our quarterly operating results to fluctuate. We therefore
believe that quarter-to-quarter comparisons of our operating results may not be
a good indication of our future performance, and you should not rely on them to
predict our future performance or the future performance of our stock price. Our
short-term expense levels are relatively fixed and are based on our expectations
of future revenues. As a result, a reduction in revenues in a quarter may harm
our operating results for that quarter. Our quarterly revenues, expenses and
operating results could vary significantly from quarter-to-quarter. If our
operating results in

                                       4
6

future quarters fall below the expectations of market analysts and investors,
the trading price of our common stock will fall. Factors that may cause our
operating results to fluctuate on a quarterly basis are:

     o    varying size, timing and contractual terms of orders for our products,

     o    our ability to timely complete our service obligations related to
          product sales,

     o    changes in the mix of revenue attributable to higher-margin product
          license revenue as opposed to substantially lower-margin service
          revenue,

     o    customers' decisions to defer orders or implementations, particularly
          large orders or implementations, from one quarter to the next,

     o    changes in demand for our software or for enterprise software and real
          time marketing solutions generally,

     o    announcements or introductions of new products by our competitors,

     o    software defects and other product quality problems,

     o    our ability to integrate acquisitions,

     o    any increase in our need to supplement our professional services
          organization by subcontracting to more expensive consulting
          organizations to help provide implementation, support and training
          services when our own capacity is constrained, and

     o    our ability to hire, train and retain sufficient engineering,
          consulting, training and sales staff.

THE LOSS OF KEY PERSONNEL, OR ANY INABILITY TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL, COULD AFFECT OUR ABILITY TO SUCCESSFULLY GROW OUR BUSINESS.

     Our future success will depend in large part on our ability to hire and
retain a sufficient number of qualified personnel, particularly in sales,
marketing, research and development, service and support. If we are unable to do
so, this inability could affect our ability to grow our business. Competition
for qualified personnel in high technology is intense, particularly in the
Silicon Valley region of Northern California where our principal offices are
located. Our future success also depends upon the continued service of our
executive officers and other key sales, engineering and technical staff. The
loss of the services of our executive officers and other key personnel would
harm our operations. None of our officers or key personnel are bound by an
employment agreement and we do not maintain key person insurance on any of our
employees. We would also be harmed if one or more of our officers or key
employees decided to join a competitor or otherwise compete with us.

     The market price of our common stock has fluctuated substantially since our
initial public offering in September 1999. Consequently, potential employees may
perceive our equity incentives such as stock options as less attractive and
current employees whose options are no longer priced below market value may
choose not to remain employed by us. In that case, our ability to attract or
retain employees will be adversely affected.

IF CUSTOMERS DO NOT CONTRACT DIRECTLY WITH CONSULTING ORGANIZATIONS TO IMPLEMENT
AND SUPPORT OUR PRODUCTS, OUR REVENUES, PROFITABILITY AND MARGINS MAY BE HARMED.

     Our principal focus is providing software solutions rather than services.
As a result, we encourage our customers to purchase consulting, implementation,
maintenance and training services directly from consulting organizations instead
of purchasing these services from us. While we do not receive any fees directly
from these consulting organizations when they contract directly with our
customers, we believe that these consulting organizations increase market
awareness and acceptance of our software solutions and allow us to focus on
software development and licensing. If consulting organizations are unwilling or
unable to provide a sufficient level and quality of services directly to our
customers or if customers are unwilling to contract directly with these
consulting organizations, we may not realize these benefits and our revenues and
profitability may be harmed.

     Further, to the extent that consulting organizations do not provide
consulting, implementation, maintenance and training services directly to our
customers, we need to provide these services to our customers. We provide these
services to our customers either directly through our internal professional
services organization or indirectly through subcontractors we hire to perform
the services on our behalf. Because our margins on service revenues are less
than our margins on license revenues, our overall margins decline when we
provide services to customers. This is particularly true if we hire
subcontractors to perform these services because it costs us more to hire
subcontractors to perform these services than to provide the services ourselves.

IF OUR INTERNAL PROFESSIONAL SERVICES ORGANIZATION DOES NOT PROVIDE
IMPLEMENTATION SERVICES EFFECTIVELY AND ACCORDING TO SCHEDULE, OUR REVENUES AND
PROFITABILITY WOULD BE HARMED.

     Customers that license our products typically require consulting,
implementation, maintenance and training services and obtain them from our
internal professional services, customer support and training organizations,
which employed a staff of 282 as of September 30, 2000, or from outside
consulting organizations. When we provide these services, we generally recognize
revenue from the licensing of our software products as the implementation
services are performed. If our internal professional services organization does
not effectively implement and support our products or if we are unable to expand
our internal professional services organization as needed to meet our customers'
needs, our ability to sell software, and accordingly our revenues, will be
harmed.

     In addition, when we sell licenses together with professional services for
implementation, we generally recognize the revenue from both the license and the
services as we perform the implementation services. Therefore, delays in
providing implementation services will delay our recognition of revenue. If we
are unable to expand our internal professional services organization to keep
pace with sales, we will be required to increase our use of subcontractors to
help meet our implementation and service obligations, which will result in lower
gross margins. In addition, we may be unable to negotiate agreements with
subcontractors to provide a sufficient level and quality of services. If we fail
to retain sufficient subcontractors, our ability to sell software for which
these services are required will be harmed and our revenues will suffer.

OUR SERVICE REVENUES HAVE A SUBSTANTIALLY LOWER MARGIN THAN OUR PRODUCT
REVENUES, AND AN INCREASE IN SERVICE REVENUES RELATIVE TO LICENSE REVENUES COULD
HARM OUR GROSS MARGINS.

     Our service revenues, which includes fees for consulting, implementation,
maintenance and training, were 44% of our revenues for the nine months ended
September 30, 2000, 47% of our revenues for the year ended December 31, 1999 and
34% of our revenues for the year ended December 31, 1998. Our service revenues
have substantially lower gross margins than license revenues. Our cost of
service revenues for the nine months ended September 30, 2000 and the year ended
December 31,1999 was 96% and 102%, respectively, of our service

                                       6
8

revenues. An increase in the percentage of total revenues represented by
services revenues could adversely affect our overall gross margins.

     Service revenues as a percentage of total revenues and cost of service
revenues as a percentage of total revenues have varied significantly from
quarter to quarter due to our relatively early stage of development. The
relative amount of service revenues as compared to license revenues has varied
based on the volume of software solution orders compared to the volume of
additional user orders. In addition, the amount and profitability of services
can depend in large part on:

     o    the software solution which has been licensed,

     o    the complexity of the customers' information technology environment,

     o    the resources directed by customers to their implementation projects,

     o    the number of users licensed, and

     o    the extent to which outside consulting organizations provide services
          directly to customers.

NEW PRODUCT INTRODUCTIONS AND PRICING STRATEGIES BY OUR COMPETITORS COULD
ADVERSELY AFFECT OUR ABILITY TO SELL OUR PRODUCTS AND COULD RESULT IN PRESSURE
TO PRICE OUR PRODUCTS IN A MANNER THAT REDUCES OUR MARGINS.

     Competitive pressures could prevent us from growing, reduce our market
share or require us to reduce prices on our products and services, any of which
could harm our business.

     We compete principally with vendors of:

     o    enterprise application software, such as Oracle, PeopleSoft, SAP and
          Siebel Systems,

     o    data management and data analysis software tools, such as Broadbase,
          Business Objects, Informatica, and Microstrategy,

     o    marketing campaign management software tools, such as Exchange
          Applications, Prime Response, and Recognition Systems,

     o    software that recommends products to customers in real-time such as
          Net Perceptions, and

     o    electronic customer relationship management software, such as Kana
          Communications, eGain, and Primus Knowledge Solutions.

     Many of these companies have significantly greater financial, technical,
marketing, service and other resources. Many of these companies also have a
larger installed base of users, have been in business longer or have greater
name recognition than we do. Some large companies may attempt to build
capabilities into their products that are similar to the capabilities of our
products. Some of our competitors' products may be more effective than our
products at performing particular functions or be more customized for particular
needs. Even if these functions are more limited than those provided by our
products, our competitors' software products could discourage potential
customers from purchasing our products. For example, our competitors' software
products may incorporate other capabilities,

                                       7
9

such as recording accounting transactions, customer orders or inventory
management data. A software product that performs these functions, as well as
some of the functions of our software solutions, may be appealing to some
customers because it would reduce the number of different types of software
necessary to effectively run their business. Further, our competitors may be
able to respond more quickly than we can to changes in customer requirements.

     In addition, our products must integrate with software solutions provided
by a number of our existing or potential competitors. These competitors could
alter their products so that our products no longer integrate well with them, or
they could deny or delay access by us to advance software releases that allow us
to timely adapt our products to integrate with their products.

     Our competitors have made and may also continue to make strategic
acquisitions or establish cooperative relationships among themselves or with
other software vendors. This may increase the ability of their products to
address the need for software solutions such as ours, which provide both the
ability to collect data from multiple sources and analyze that data to profile
customer characteristics and preferences. Our competitors may also establish or
strengthen cooperative relationships with our current or future distributors or
other parties with whom we have relationships, thereby limiting our ability to
sell through these channels, reducing promotion of our products and limiting the
number of consultants available to implement our software.

OUR REVENUES MIGHT BE HARMED BY RESISTANCE TO ADOPTION OF E.PIPHANY'S SOFTWARE
BY INFORMATION TECHNOLOGY DEPARTMENTS.

     Some businesses may have already made a substantial investment in other
third party or internally developed software designed to integrate data from
disparate sources and analyze this data or manage marketing campaigns. These
companies may be reluctant to abandon these investments in favor of our
software. In addition, information technology departments of potential customers
may resist purchasing our software solutions for a variety of other reasons,
particularly the potential displacement of their historical role in creating and
running software and concerns that packaged software products are not
sufficiently customizable for their enterprises. If the market for our products
does not grow for any of these reasons, our revenues will be harmed.

IF THE MARKET IN WHICH WE SELL OUR PRODUCTS AND SERVICES DOES NOT GROW AS WE
ANTICIPATE, OUR REVENUES WILL BE REDUCED.

     If the market for software that enables companies to establish, manage,
maintain and continually improve customer relationships by collecting and
analyzing data to design and manage marketing campaigns and customize products
and services and providing timely, consistent, multichannel customer interaction
does not grow as quickly or become as large as we anticipate, our revenues will
be reduced. Our market is still emerging, and our success depends on its growth.
Our potential customers may:

     o    not understand or see the benefits of using these products,

     o    not achieve favorable results using these products,

     o    experience technical difficulty in implementing or using these
          products, or

     o    use alternative methods to solve the same business problems.

                                       8
10

     In addition, because our products can be used in connection with Internet
commerce and we are currently developing additional Internet commerce solutions,
if the Internet commerce market does not grow as quickly as we anticipate, we
may experience sales, which are lower than our expectations.

IF WE FAIL TO DEVELOP NEW PRODUCTS OR IMPROVE OUR EXISTING PRODUCTS TO MEET OR
ADAPT TO THE CHANGING NEEDS AND STANDARDS OF OUR INDUSTRY, SALES OF OUR PRODUCTS
MAY DECLINE.

     Our future success depends on our ability to address the rapidly changing
needs of our customers and potential customers. We must maintain and improve our
E.piphany E.5 System and develop new products that include new technological
developments, keep pace with products of our competitors and satisfy the
changing requirements of our customers. If we do not, we may not achieve market
acceptance and we may be unable to attract new customers. E.piphany may also
lose existing customers, to whom we seek to sell additional software solutions
and professional services.

     To achieve increased market acceptance of our products, we must, among
other things, continue to:

     o    improve and introduce new software solutions for reporting and
          analysis, distributed database marketing and e-commerce,

     o    improve the effectiveness of our software, particularly in
          implementations involving very large databases and large numbers of
          simultaneous users,

     o    enhance our software's ease of administration,

     o    improve our software's ability to extract data from existing software
          systems, and

     o    adapt to rapidly changing computer operating system and database
          standards and Internet technology.

     We may not be successful in developing and marketing these or other new or
improved products. If we are not successful, we may lose sales to competitors.

     In addition, we have entered into customer contracts, which contain
specific performance goals relating to new product releases or enhancements, and
if we are not able to meet these goals, we may be required to, among other
things, return fees, pay damages and offer discounts.

IF OUR PRODUCTS DO NOT STAY COMPATIBLE WITH CURRENTLY POPULAR SOFTWARE PROGRAMS,
WE MAY LOSE SALES AND REVENUES.

     The E.piphany E.5 System must work with commercially available software
programs that are currently popular. If these software programs do not remain
popular, or we do not update our software to be compatible with newer versions
of these programs, we may lose customers.

     In order to operate the E.piphany E.5 System, the system must be installed
on both a computer server running the Microsoft Windows NT or Windows 2000
computer operating systems and a computer server running database software from
Microsoft or Oracle. E.piphany is currently modifying its respective software to
also operate on UNIX operating systems and IBM DB2 databases. If we fail to
successfully complete these modifications in a timely manner, we may lose sales
and revenues. In addition, users access the E.piphany

                                       9
11

E.5 System through standard Internet browsers such as Microsoft Internet
Explorer. If we fail to obtain access to developer versions of these software
products, we may be unable to build and enhance our products on schedule.

     After installation, the E.piphany E.5 System collects and analyzes data to
profile customers' characteristics and preferences. This data may be stored in a
variety of our customers' existing software systems, including leading systems
from Oracle, PeopleSoft, Siebel Systems, SAP and Vantive, running on a variety
of computer operating systems. If we fail to enhance our software to collect
data from new versions of these products, we may lose potential customers. If we
lose customers, our revenues and profitability may be harmed.

IF DATABASE ACCESS BECOMES STANDARDIZED, DEMAND FOR OUR PRODUCTS WILL BE
REDUCED.

     Our products are useful for integrating data from a variety of disparate
data sources. Adoption of uniform, industry-wide standards across various
database and analytic software programs could minimize the importance of the
data integration capabilities of our products. This, in turn, could adversely
affect the competitiveness and market acceptance of our products. Also, a single
competitor in the market for database and analytic software programs or Internet
relationship management may become dominant, even if there is no formal
industry-wide standard. If large numbers of our customers adopt a single
standard, this would similarly reduce demand for our product. If E.piphany loses
customers because of the adoption of standards, we may have lower revenues and
profitability.

OUR PRODUCTS HAVE LONG SALES CYCLES WHICH MAKES IT DIFFICULT TO PLAN EXPENSES
AND FORECAST RESULTS.

     It takes us between three and six months to complete the majority of our
sales, but it can take us up to one year or longer. It is therefore difficult to
predict the quarter in which a particular sale will occur and to plan
expenditures accordingly. The period between initial contact with a potential
customer and their purchase of products and services is relatively long due to
several factors, including:

     o    the complex nature of our products,

     o    our need to educate potential customers about the uses and benefits of
          our products,

     o    the purchase of our products requires a significant investment of
          resources by a customer,

     o    our customers have budget cycles which affect the timing of purchases,

     o    many of our customers require competitive evaluation and internal
          approval before purchasing our products,

     o    potential customers may delay purchases due to announcements or
          planned introductions of new products by E.piphany or its competitors,
          and

     o    many of our customers are large organizations, which may require a
          long time to make decisions.

     The delay or failure to complete sales in a particular quarter could reduce
our revenues in that quarter, as well as subsequent quarters over which revenues
for the sale would likely be recognized. If our sales cycle unexpectedly
lengthens in general or for one or more large orders, it would adversely affect
the timing of our revenues. If we were to experience a delay of several weeks on
a large order, it could harm our ability to meet our forecasts for a given
quarter.

IF WE FAIL TO ESTABLISH, MAINTAIN OR EXPAND OUR RELATIONSHIPS WITH THIRD
PARTIES, OUR ABILITY TO GROW REVENUES COULD BE HARMED.

     In order to grow our business, we must generate, retain and strengthen
relationships with third parties. To date, we have established relationships
with several companies, including consulting organizations and system
integrators that implement our software, including Ernst & Young, KPMG and
PricewaterhouseCoopers; resellers, including Acxiom, Harte-Hanks and Pivotal;
and application service providers that provide access to our software to their
customers over the Internet, including Corio and Interrelate. If the third
parties with whom we have relationships do not provide sufficient, high-quality
service or integrate and support our software correctly, our revenues may be
harmed. In addition, the third parties with whom we have relationships may offer
products of other companies, including products that compete with our products.
We typically enter into contracts with third parties that generally set out the
nature of our relationships. However, our contracts do not require these third
parties to devote resources to promoting, selling and supporting our products.
Therefore we have little control over these third parties. We cannot assure you
that we can generate and maintain relationships that offset the significant time
and effort that are necessary to develop these relationships.

     We must also effectively take advantage of the resources and expertise of
third parties to help them develop the E.piphany E.5 System. Our agreements with
third parties do not require them to help us develop new software. If we fail to
effectively work with third parties, our ability to increase revenues by
broadening our software solution offerings, particularly in additional specific
industries, will be limited.

IF WE FAIL TO EXPAND OUR DIRECT AND INDIRECT SALES CHANNELS, WE WILL NOT BE ABLE
TO INCREASE REVENUES.

     In order to grow our business, we need to increase market awareness and
sales of our products and services. To achieve this goal, we need to increase
both our direct and indirect sales channels. If we fail to do so, this failure
could harm our ability to increase revenues. We currently receive substantially
all of our revenues from direct sales, but we intend to increase sales through
indirect sales channels in the future. We also need to expand our direct sales
force by hiring additional salespersons and sales management.

     We intend to derive revenues from indirect sales channels by selling our
software through value added resellers. These resellers offer our software
products to their customers together with consulting and implementation services
or integrate our software solutions with other software. We also intend to
increasingly offer our software through application service providers, who
install our software on their own computer servers and charge their customers
for access to that software. We need to expand our indirect sales channels by
entering into additional relationships with these third parties.

     We have not derived a material amount of revenues from international sales
to date, but we expect as part of our strategy to increase international sales
principally through the use of indirect sales channels. We will be even more
dependent on indirect sales channels in the future due to our international
strategy. We also plan to use international direct sales personnel and therefore
must hire additional sales personnel outside the United States. Our ability to
develop and maintain these channels will significantly affect our ability to
penetrate international markets.

WE HAVE GROWN VERY QUICKLY AND IF WE FAIL TO MANAGE OUR GROWTH, OUR ABILITY TO
GENERATE NEW REVENUES AND ACHIEVE PROFITABILITY WOULD BE HARMED.

     We have grown significantly since our inception and will need to grow
quickly in the future. Any failure to manage this growth could impede our
ability to increase revenues and achieve profitability. We have increased our
number of employees from 21 at December 31, 1997 to 849 as of September 30,
2000. Our

                                       11
13

future expansion could be expensive and strain our management and other
resources. In order to manage growth effectively, we must:

     o    hire, train and integrate new personnel,

     o    integrate people and technologies from acquired companies,

     o    continue to augment our financial and accounting systems,

     o    manage our sales operations, which are in several locations,

     o    expand our facilities, and

     o    if we do not manage our growth effectively, our business could suffer.

IF WE ACQUIRE ADDITIONAL COMPANIES OR TECHNOLOGIES IN THE FUTURE, THEY COULD
PROVE DIFFICULT TO INTEGRATE, DISRUPT OUR BUSINESS, DILUTE STOCKHOLDER VALUE OR
ADVERSELY AFFECT OUR OPERATING RESULTS.

     In addition to the acquisitions that we have already completed, we may
acquire or make investments in other complementary companies, services and
technologies in the future. If we fail to properly evaluate and execute
acquisitions and investments, they may seriously harm our business and
prospects. To successfully complete an acquisition, we must:

     o    properly evaluate the business, personnel and technology of the
          company to be acquired,

     o    accurately forecast the financial impact of the transaction, including
          accounting charges and transaction expenses,

     o    integrate and retain personnel,

     o    combine potentially different corporate cultures,

     o    effectively integrate products and research and development, sales,
          marketing and support operations, and

     o    maintain focused on our day-to-day operations.

     Further, the financial consequences of our acquisitions and investments may
include potentially dilutive issuances of equity securities, one-time
write-offs, amortization expenses related to goodwill and other intangible
assets and the incidence of contingent liabilities.

IF OTHERS CLAIM THAT WE ARE INFRINGING THEIR INTELLECTUAL PROPERTY, WE COULD
INCUR SIGNIFICANT EXPENSES OR BE PREVENTED FROM SELLING OUR PRODUCTS.

     We cannot assure you that others will not claim that we are infringing
their intellectual property rights or that we do not in fact infringe those
intellectual property rights. We have not conducted a search for existing
intellectual property registrations and we may be unaware of intellectual
property rights of others that may cover some of our technology.

     We have been contacted by a company which has asked us to evaluate the need
for a license of several patents that the company holds directed to data
extraction technology. This company has filed litigation alleging infringement
of its patents against several of our competitors. We cannot assure you that the
holder of the patents will not file litigation against us or that we would
prevail in the case of such litigation. In addition, the patent holder has
informed us that it has applications pending in numerous foreign countries. The
patent holder may also have applications on file in the United States covering
related subject matter which are confidential until the patent or patents, if
any, is issued.

     Any litigation regarding intellectual property rights could be costly and
time-consuming and divert the attention of our management and key personnel from
our business operations. The complexity of the technology involved and the
uncertainty of intellectual property litigation increase these risks. Claims of
intellectual property infringement might also require us to enter into costly
royalty or license agreements.

     However, we may not be able to obtain royalty or license agreements on
terms acceptable to us, or at all. We also may be subject to significant damages
or an injunction against use of our products. A successful claim of patent or
other intellectual property infringement against us would have an immediate
material adverse effect on our business and financial condition.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, THIS INABILITY
COULD WEAKEN OUR COMPETITIVE POSITION, REDUCE OUR REVENUES AND INCREASE OUR
COSTS.

     Our success depends in large part on our proprietary technology. We rely on
a combination of patent, copyright, trademark and trade secrets, confidentiality
procedures and licensing arrangements to establish and protect our proprietary
rights. We may be required to spend significant resources to monitor and police
our intellectual property rights. If we fail to successfully enforce our
intellectual property rights, our competitive position may be harmed.

                                       12
14

     Our pending patent and trademark registration applications may not be
allowed or competitors may successfully challenge the validity or scope of these
registrations. In addition, our patents may not provide a significant
competitive advantage.

     Other software providers could copy or otherwise obtain and use our
products or technology without authorization. They also could develop similar
technology independently which may infringe our proprietary rights. We may not
be able to detect infringement and may lose a competitive position in the market
before it does so. In addition, competitors may design around our technology or
develop competing technologies. The laws of some foreign countries do not
protect proprietary rights to the same extent as do the laws of the United
States.

     In addition, one of the ways in which we charge for our software is based
on the number of users at a particular site that will be permitted to use the
software. Organizations that have a site license for a fixed number of users for
our products could allow unauthorized use of our software by unlicensed users.
Unauthorized use is difficult to detect and, to the extent that our software is
used without authorization, we may lose potential license fees.

PRIVACY AND SECURITY CONCERNS, PARTICULARLY RELATED TO THE USE OF OUR SOFTWARE
ON THE INTERNET, MAY LIMIT THE EFFECTIVENESS OF AND REDUCE THE DEMAND FOR OUR
PRODUCTS.

     The effectiveness of our software products relies on the storage and use of
customer data collected from various sources, including information collected on
Web sites, as well as other data derived from customer registrations, billings,
purchase transactions and surveys. Our collection and use of such data for
customer profiling may raise privacy and security concerns. Our customers
generally have implemented security measures to protect customer data from
disclosure or interception by third parties. However, the security measures may
not be effective against all potential security threats. If a well-publicized
breach of customer data security were to occur, our software products may be
perceived as less desirable, impacting our future sales and profitability.

     In addition, due to privacy concerns, some Internet commentators, consumer
advocates, and governmental or legislative bodies have suggested legislation to
limit the use of customer profiling technologies. The European Union and some
European countries have already adopted some restrictions on the use of customer
profiling data. In addition, Internet users can, if they choose, configure their
Web browsers to limit the collection of user data for customer profiling. Should
many Internet users choose to limit the use of customer profiling technologies,
or if major countries or regions adopt legislation or other restrictions on the
use of customer profiling data, E.piphany's software would be less useful to
customers, and E.piphany's sales and profits could decrease.

OUR PRODUCTS ARE NEW, AND IF THEY CONTAIN DEFECTS, OR OUR SERVICES ARE NOT
PERCEIVED AS HIGH QUALITY, WE COULD LOSE POTENTIAL CUSTOMERS OR BE SUBJECT TO
DAMAGES.

     We began shipping our first products in early 1998. These products are
complex and may contain currently unknown errors, defects or failures,
particularly since they are new and recently released. In the past we have
discovered software errors in some of our products after introduction. We may
not be able to detect and correct errors before releasing our products
commercially. If our commercial products contain errors, we may be required to:

     o    expend significant resources to locate and correct the error,

                                       13
15

     o    delay introduction of new products or commercial shipment of products,
          or

     o    experience reduced sales and harm to our reputation from dissatisfied
          customers.

     Our customers also may encounter system configuration problems which
require us to spend additional consulting or support resources to resolve these
problems.

     In addition, our customers generally store their data across computer
networks, which are often connected to the Internet. Our software operates
across our customers' computer networks and can, at the customer's option, be
accessed through an Internet connection. Our software contains technology
designed to prevent theft or loss of data. Nevertheless, customers may encounter
security issues with their existing databases installed across networks,
particularly the Internet, or with our software. A security breach involving our
software, or a widely publicized security breach involving the Internet
generally, could harm our sales. A security breach involving our software could
also expose us to claims for damages.

     Because our software products are used for important decision-making
processes and enable our customers to interact with their customers, product
defects may also give rise to product liability claims. Although our license
agreements with customers typically contain provisions designed to limit our
exposure, some courts may not enforce all or part of these limitations. Although
we have not experienced any product liability claims to date, we may encounter
these claims in the future. Product liability claims, whether or not successful,
could:

     o    divert the attention of our management and key personnel from our
          business,

     o    be expensive to defend, and

     o    result in large damage awards.

     Our product liability insurance may not be adequate to cover all of the
expenses resulting from a claim. In addition, if our customers do not find our
services to be of high quality, they may elect to use other training, consulting
and product integration firms rather than contract for our services. If
customers are dissatisfied with our services, we may lose revenues.

WE INTEND TO EXPAND OUR INTERNATIONAL SALES EFFORTS BUT WE DO NOT HAVE
SUBSTANTIAL EXPERIENCE IN INTERNATIONAL MARKETS.

     Although our international sales have been immaterial to date, we intend to
expand our international sales efforts in the future. We have limited experience
in marketing, selling and supporting our products and services abroad. If we are
unable to grow our international operations successfully and in a timely manner,
our business and operating results could be seriously harmed. In addition, doing
business internationally involves greater expense and many additional risks,
particularly:

     o    unexpected changes in regulatory requirements, taxes, trade laws and
          tariffs,

     o    differing intellectual property rights,

     o    differing labor regulations,

     o    unexpected changes in regulatory requirements,

                                       14
16

     o    changes in a specific country's or region's political or economic
          conditions,

     o    greater difficulty in establishing, staffing and managing foreign
          operations, and

     o    fluctuating exchange rates.

     We plan to expand our international operations in the near future, and this
will require a significant amount of attention from our management and
substantial financial resources. We have begun efforts at international
expansion in Europe and, as of September 30, 2000, had 51 sales and marketing
professionals located in the United Kingdom, Australia, Germany, Canada, Japan,
The Netherlands and France. We are also exploring other regions for future
expansion.

SEASONAL TRENDS IN SALES OF BUSINESS SOFTWARE MAY AFFECT OUR QUARTERLY REVENUES.

     The market for business software has experienced seasonal fluctuations in
demand. The first and third quarters of the year have been typically
characterized by lower levels of revenue growth. We believe that these
fluctuations are caused in part by customer buying patterns, which are
influenced by year-end budgetary pressures and by sales force commission
structures. As our revenues grow, we may experience seasonal fluctuations in our
revenues.

                                       15

WE DO NOT INTEND TO PAY DIVIDENDS, YOU WILL NOT RECEIVE FUNDS WITHOUT SELLING
SHARES AND YOU MAY LOSE THE ENTIRE AMOUNT OF YOUR INVESTMENT.

     We have never declared or paid any cash dividends on our capital stock and
do not intend to pay dividends in the foreseeable future. We intend to invest
our future earnings, if any, to fund our growth. Therefore, you will not receive
any funds without selling your shares. We further cannot assure you that you
will receive a return on your investment when you sell your shares or that you
will not lose the entire amount of your investment.

PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY DELAY OR PREVENT AN
ACQUISITION OF E.PIPHANY.

     Our certificate of incorporation and bylaws contain provisions which could
make it harder for a third party to acquire us without the consent of our board
of directors. For example, if a potential acquiror were to make a hostile bid
for us, the acquiror would not be able to call a special meeting of stockholders
to remove our board of directors or act by written consent without a meeting. In
addition, our board of directors have staggered terms, which makes it difficult
to remove them all at once. The acquiror would also be required to provide
advance notice of its proposal to remove directors at an annual meeting. The
acquiror also will not be able to cumulate votes at a meeting, which will
require the acquiror to hold more shares to gain representation on the board of
directors than if cumulative voting were permitted.

     Our board of directors also has the ability to issue preferred stock which
would significantly dilute the ownership of a hostile acquiror. In addition,
Section 203 of the Delaware General Corporation Law limits business combination
transactions with 15% stockholders that have not been approved by the board of
directors. These provisions and other similar provisions make it more difficult
for a third party to acquire us without negotiation. These provisions may apply
even if the offer may be considered beneficial by some stockholders.

     Our board of directors could choose not to negotiate with an acquiror that
it did not feel was in the strategic interests of our company. If the acquiror
was discouraged from offering to acquire us, or prevented from successfully
completing a hostile acquisition by the antitakeover measures, you could lose
the opportunity to sell your shares at a favorable price.

                                 E.PIPHANY, INC.

     We develop, market and sell the E.piphany E.5 System, an integrated suite
of customer relationship management software solutions that provides
capabilities for the analysis of customer data, the creation of inbound and
outbound marketing campaigns, and the execution of sales and service customer
interactions. Companies can implement the E.piphany E.5 System to collect and
analyze data from their existing software systems, and from third party data
providers, to better understand and proactively and personally interact with
their customers across a variety of channels. Business users within these
companies can use this information to design and execute marketing campaigns as
well as personalize products, services and related interactions. Our
headquarters are located at 1900 South Norfolk Street, Suite 310, San Mateo,
California 94403 and the telephone number is (650) 356-3800.

                                 USE OF PROCEEDS

     Because the shares of our common stock offered hereunder are being offered
by a stockholder of E.piphany, Inc., we will receive no proceeds upon the sale
of such common stock.

                              PLAN OF DISTRIBUTION

     The selling stockholder may, from time to time, sell all or a portion of
the shares as follows:

     o    at prices and at terms then prevailing in the market,

     o    at prices related to the then current market price, or

     o    in negotiated transactions.

     The shares may be sold by the selling stockholder by one or more of the
following methods, or others:

     o    block trades in which the broker or dealer so engaged will attempt to
          sell the shares as agent but may position and resell a portion of the
          block as principal to facilitate the transaction,

     o    purchases by a broker or dealer as principal and resale by the broker
          or dealer for its account pursuant to this prospectus,

     o    on a stock exchange in accordance with the rules of the particular
          exchange,

     o    ordinary brokerage transactions and transactions in which the broker
          solicits purchasers,

     o    privately negotiated transactions, or

     o    a combination of any of these methods of sale.

     In effecting sales, brokers and dealers engaged by the selling stockholder
may arrange for other brokers or dealers to participate. Brokers or dealers may
receive commissions or discounts from the selling stockholder, or, if any
broker-dealer acts as agent for the purchaser of the shares, from the purchaser,
in amounts to be negotiated which are not expected to exceed those customary in
the types of transactions involved. Broker-dealers may agree with the selling
stockholder to sell a specified number of the shares at a stipulated price per
share, and, to the extent the broker-dealer is unable to do so acting as agent
for the selling

                                       17
19

stockholder, to purchase as principal any unsold shares at the price required to
fulfill the broker-dealer commitment to the selling stockholder. Broker-dealers
who acquire shares as principal may subsequently resell the shares from time to
time in the following transactions:

     o    transactions, which may involve block transactions and sales to and
          through other broker-dealers, in the over-the-counter market or
          otherwise at prices and on terms then prevailing at the time of sale,

     o    in negotiated transactions, or

     o    at prices related to the then-current market price.

     In connection with these resales, the broker-dealer may pay to or receive
from the purchasers of the shares commissions as described above.

     The selling stockholder and any broker-dealers or agents that participate
with the selling stockholder in sales of the shares may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with any
sales. In the event of a sale, any commissions received by the broker-dealers or
agents and any profit on the resale of the shares purchased by them may be
deemed to be underwriting commissions or discounts under the Securities Act. In
addition, Regulation M under the Securities Exchange Act of 1934, as amended,
may apply in connection with the selling stockholder's sales of his shares.

     We have agreed to pay all fees and expenses incident to the registration of
the shares. The selling stockholder will pay all commissions and discounts, if
any, attributable to the sales of the shares. We have agreed to indemnify the
selling stockholder against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act.

     We will file a supplement to this prospectus, if required, upon being
notified by the selling stockholder that any material arrangement has been
entered into for the sale of the shares though a block trade, or as otherwise
may be required.

     The selling stockholder may, in the future, also sell the shares in
accordance with Rule 144 under the Securities Act, rather than pursuant to this
prospectus.

     There can be no assurance that the selling stockholder will sell any or all
of the shares of common stock offered by him hereunder.

                               SELLING STOCKHOLDER

     The shares of our common stock to be offered and sold pursuant to this
prospectus were issued to the selling stockholder in connection with the
commencement of his employment as our Chief Executive Officer. The following
table sets forth information with respect to beneficial ownership of our common
stock as of September 30, 2000 by the selling stockholder. Except as indicated
in the footnotes to this table:

     o    The person named in the table has sole voting and investment power
          with respect to all shares of common stock shown as beneficially owned
          by him, subject to community property laws where applicable, and

     o    The selling stockholder has not held any position or office or had a
          material relationship with E.piphany, Inc. or any of our affiliates
          within the past three years other than as a result of his ownership of
          the shares of our common stock or as a result of their employment with
          us.

     The shares offered by this prospectus may be offered from time to time by
the selling stockholder named below. The selling stockholder may offer all, some
or none of the shares and there currently are no agreements, arrangements or
understandings with respect to the sale of any of the shares.

     The audited financial statements incorporated in this prospectus by
reference from E.piphany, Inc.'s Annual Report on Form 10-K for the fiscal years
ended December 31, 1997, 1998 and 1999 have been audited by Arthur Andersen LLP,
independent public accountants, as indicated in their reports with respect
thereto, which are incorporated herein by reference, and have been so
incorporated in reliance upon the authority of said firm as experts in
accounting and auditing.

                  CHANGE IN OUR INDEPENDENT PUBLIC ACCOUNTANTS

     In July 1998, KPMG LLP resigned as our independent public accountants, as
KPMG LLP became an integrator of our products and purchased our preferred stock.
The former independent accountants' report on our financial statements for the
year ended December 31, 1997 did not contain an adverse opinion, a disclaimer of
opinion or any qualifications or modifications related to uncertainty,
limitation of audit scope or application of accounting principles. The former
independent public accountants' report does not cover any of our financial
statements in this registration statement. KPMG LLP did not issue an audit
opinion on our financial statements for any other period. There were no
disagreements with the former public accountants on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure with respect to our financial statements up through the time of
dismissal that, if not resolved to the former accountants' satisfaction, would
have caused them to make reference to the subject matter of the disagreement in
connection with their report. In September 1998, we retained Arthur Andersen LLP
as our independent public accountants. The decision to retain Arthur Andersen
LLP was approved by resolution of our board of directors. Prior to retaining
Arthur Andersen LLP, we had not consulted with Arthur Andersen LLP regarding
accounting principles.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

     Article VII of the Registrant's Amended and Restated Certificate of
Incorporation provides for the indemnification of directors to the fullest
extent permissible under Delaware law.

     Article VI of the Registrant's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the Registrant if such
person acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of the Registrant, and, with respect to any
criminal action or proceeding, the indemnified party had no reason to believe
his or her conduct was unlawful.

     The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
the Registrant's Bylaws, and intends to enter into indemnification agreements
with any new directors and executive officers in the future.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

     The shares of common stock being offered under this prospectus were sold to
Mr. Siboni on July 1, 1998 in connection with our hiring of Mr. Siboni as our
Chief Executive Officer at that time. The shares were offered and sold to Mr.
Siboni in reliance upon the private offering exemption provided by Section 4(2)
of the Securities Act. At the time of the offer and sale, Mr. Siboni was an
accredited investor, had such knowledge and experience in financial and business
matters that he was capable of evaluating the merits and risks of the investment
and was given the opportunity to ask questions and receive answers concerning
the terms and conditions of the offering.

ITEM 9. UNDERTAKINGS

     (a)  The undersigned Registrant hereby undertakes:

          (i)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement.

          (ii) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended (the "Securities Act") each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

          (iii) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
