Boston based VC's turning down all those deals comes as news to me. The laser sharp focus on monetization vs. utility is quite possibly the difference between a HBS type and a stanford type.
Exactly why almost every YC startup from the Boston batch that doesn't die immediately after ends up in the valley.
A bit too harsh but they got the gist of right :). Boston VCs are just way too risk averse. They prefer later, less risky, more conservative, stages.
They might as well buy mutual funds and call it a day.
