I have a side question for YC. You often mention that one of the main reasons for a startup to fail is founders dispute. But that applies to you too: you don't know the founders before accepting them. How do you trust the founders so fast? In other words, do you invest in companies in which you wouldn't want to be a founder? I just want to know more about trust, where it matters, where it doesn't maybe, what to look for, that kind of stuff. Sorry if that's irrelevant here.
