I've regretted leaving a startup at the time I did. I was miserable, but probably could've stuck in there for 10 months if I'd seen the liquidity event that was coming. In my experience, most early founders don't quit because they're discouraged by lack of traction. That's why advisors and investors quit. Founders quit because of a difference of opinion around product vision and because relationships are just plain broken. One of my colleagues put it this way, "If you look at the people around you and feel sad because you're helping people you hate (who you used to like) win, that's when you need to quit."
