Losing focus is another way that founders get off track.

Before product/market fit, your only job that matters is to build a great product.

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

... 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.

... you can think about that for everyone you hire: will I bet the future of this company on this single hire? And that's a tough bar.

Most of the best hires that I've made in my entire life have never done that thing before.

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