You can win with the best product, the best price, or the best experience.

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

Companies that I've been very involved with, that have had a very bad first hire in the first 3 or so employees never recover from it.

When lack of structure fails, it fails all at once. What works totally fine from 0-20 employees, is disastrous at 30.

Later, you should learn to hire fast and scale up the company, but in the early days the goal should be not to hire. Not to hire.

You never want to be in a place where an employee has vested 3 out of the 4 years of stock and they start thinking about leaving.

If you pivot, do it fully and with conviction. The worst thing is to try to do a bit of the old and the new-it's hard to kill your babies.
