Random thought: Companies like optimizely have key data on its customers (conversion rates) and it may be valuable to a VC to have a board seat / access for the data alone. Not alleging any malfeasance here, just think it is an interesting angle.
I am not sure why this got downvoted. Using cloud services for your a/b testing can reveal key competitive information to the company. So trust is a big issue. That is one reason why I try to keep everything inside GA.
