originally granted under the RevelOps Plan and assumed by the Registrant, and (ii)&nbsp;1,500,000 additional shares of Common Stock, issuable pursuant to the 2015 Plan. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Pursuant to the Merger Agreement, Linda Merger Sub, Inc. merged with and into RevelOps, Inc. on October&nbsp;13, 2015 (the &#147;Effective Time&#148;).
Immediately following the Effective Time, RevelOps, Inc. merged with and into Rapid7 LLC, a wholly owned subsidiary of the Registrant. In accordance with the Merger Agreement, at the Effective Time, the Registrant assumed options to purchase shares
of Common Stock originally granted under the RevelOps Plan that were (i)&nbsp;unexpired, unexercised and outstanding as of immediately prior to the Effective Time and (ii)&nbsp;held by individuals who, immediately following the Effective Time, were
employees of RevelOps or its subsidiaries or predecessors. The Registrant assumed the options subject to their continued vesting schedules and conditions and with appropriate adjustments to the number of shares into which the options are exercisable
and the exercise price of such options, in accordance with the terms of the Merger Agreement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The additional 1,500,000 shares of Common Stock available
for issuance under the 2015 Plan being registered on this Registration Statement are to be used exclusively for the grant of awards (&#147;Inducement Awards&#148;) to individuals not previously an employee or non-employee director of the Registrant
(or following a bona fide period of non-employment with the Registrant), as an inducement material to the individual&#146;s entering into employment with the Registrant within the meaning of Rule&nbsp;5635(c)(4)&nbsp;of the NASDAQ Listing
Rules&nbsp;(&#147;Rule&nbsp;5635(c)(4)&#148;). The 2015 Plan was amended by the Board of Directors of the Registrant to provide for Inducement Awards without stockholder approval pursuant to Rule&nbsp;5635(c)(4). </P>

accordance with the requirements of Form S-8 under the Securities Act, to register (i) up to 221,759 of its shares of common stock, par value $0.01 per share (the "Common Stock"), issuable upon the exercise of outstanding options
originally granted under the RevelOps Plan and assumed by the Registrant, and (ii) 1,500,000 additional shares of Common Stock, issuable pursuant to the 2015 Plan.
Pursuant to the Merger Agreement, Linda Merger Sub, Inc. merged with and into RevelOps, Inc. on October 13, 2015 (the "Effective Time").
Immediately following the Effective Time, RevelOps, Inc. merged with and into Rapid7 LLC, a wholly owned subsidiary of the Registrant. In accordance with the Merger Agreement, at the Effective Time, the Registrant assumed options to purchase shares
of Common Stock originally granted under the RevelOps Plan that were (i) unexpired, unexercised and outstanding as of immediately prior to the Effective Time and (ii) held by individuals who, immediately following the Effective Time, were
employees of RevelOps or its subsidiaries or predecessors. The Registrant assumed the options subject to their continued vesting schedules and conditions and with appropriate adjustments to the number of shares into which the options are exercisable
and the exercise price of such options, in accordance with the terms of the Merger Agreement.
The additional 1,500,000 shares of Common Stock available
for issuance under the 2015 Plan being registered on this Registration Statement are to be used exclusively for the grant of awards ("Inducement Awards") to individuals not previously an employee or non-employee director of the Registrant
(or following a bona fide period of non-employment with the Registrant), as an inducement material to the individual's entering into employment with the Registrant within the meaning of Rule 5635(c)(4) of the NASDAQ Listing
Rules ("Rule 5635(c)(4)"). The 2015 Plan was amended by the Board of Directors of the Registrant to provide for Inducement Awards without stockholder approval pursuant to Rule 5635(c)(4).

Item 9.
Undertakings.
1.
Item 512(a) of Regulation S-K.
The undersigned Registrant hereby undertakes:
(a) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to 424(b) if, in the aggregate, the changes in volume and price represent no
more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and
(iii)
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;
Provided, however
, that paragraphs (a) (i) and (a) (ii) do not apply if the
information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.
(2) That, for the purpose of determining any liability under 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.
(3) 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.
2.
Item 512(b) of Regulation S-K.
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 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated
by reference in this 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.
3.
Item 512(h) of Regulation S-K
.
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 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.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe
that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Boston, Commonwealth of Massachusetts, on
October 13, 2015.
