This seems to be an office building that holds multiple businesses. MongoDB is located here according to their website (https://www.mongodb.com/company/office-locations). It is likely that there are 3 companies here. PodiumVC and Verizon Development Center are probably here too based on a web search. If you're in the area, and you can look through the door, you might be able to confirm that information. There may be a directory on the first floor.
