Startups are not the best choice for work-life balance, and that's sort of just the sad reality.

A board member of mine used to say sales fix everything in a startup, and that is really true.

In YC's case, the number one cause of early death for startups is cofounder blowups.

Experience matters for some roles and not others.

Most great companies in tech have been built by personal referrals for the first...at least 100 employees and often many more.

... but the pendulum has swung way out of whack here. A bad idea is still bad, and the pivot happy world we're in today feels suboptimal.

Another way of looking at this, is that the best companies are almost always mission oriented.
