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.

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

... fire fast when it's not working. It's better for the company, it's also better for the employee.

Investors will sort of like write the check and then, despite a lot of promises, don't usually do that much; sometimes they do.

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

It's better to have a few users love your product than for a lot of users to sort of like it.

You certainly don't need to have everything figured out in the path from here to world domination.
