At YC we have this public phrase, and it's relentlessly resourceful.

A lot of people treat choosing their cofounder with even less importance than they put on hiring. Don't do this.

I think as a rough estimate, you should aim to give about 10% of the company to the first 10 employees.

Firing people is one of the worst parts of running a company. Actually in my own experience, I think it is the worst.

You don't get to make their decisions but you do get to choose the decision makers.

It's better to have no cofounder than to have a bad cofounder, but it's still bad to be a solo founder.

Here's a good rule of thumb: don't worry about a competitor at all, until they're actually beating you with a real shipped product.
