Pros
Everyone at Quantcast wants to be helpful and make a difference. If you have a question for the CEO, you can ask the CEO. There are no off-limit people and everyone is sociable, particularly every Friday during Beer Cart. There is a beer cart (with wine and food) every Friday from 4 onwards. Whiskey is for Wednesday. Monday has Noah's Bagels for breakfast. The people at Quantcast are really happy to be at Quantcast.
Cons
Current office space is reaching limits for company, but that is being rectified this year (2016). Some issues with current space: 1) not enough small conference rooms for impromptu meetings, 2) not enough phone rooms for making recruiting calls, 3) lounge isn't big enough for all employees at once (this is where regular company meetings are held).
