Wish I could say this openly but the secret truth in the Valley is connected startups know to avoid seed/A round money from Khosla, if you can. They are very aggressive on terms and it's all about Vinod. They do plain shady stuff, like share your details and plans with their portfolio companies. At a seed stage they regular push for 50% of the equity and call it an "experiment". Then rather stick behind you, they pull the plug.
Don't believe me? Take a look at their portfolio and ask why with all of their resources so few YC companies are there. Xobni and ...? The other bigger companies all took growth equity not early money. In all my time in the Valley the gap between Vinod's public persona and the underlying truth is the biggest con I've run into. And of course he just keeps up the PR cause that's his best source of naive founders. Few others send him deals to lead. The good ones they keep to themselves and shut him out, until he gets in a growth terms (e.g. Square).
