Here is the thing you have to understand about VCs (and therefore, companies and websites that have accepted VC money), always and forever. Repeat it like a mantra.

--- Venture capitalists do not invest in the company. Venture capitalists invest in the exit. ---

Eventually any site, app whatever has a Sell Out Moment. They get bought by a big established corp, they go IPO, something. There is an "Exit". If you accept VC money, you are *promising* that Exit day is coming and it will be *big*.
