As you grow, the productivity I think, goes down with the square of the number of employees if you don't make an effort.

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.

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

We talk to a team they've gotten new things done, that's the best predictor we have that a company will be successful.

Why couldn't it have been done 2 years ago, and why will 2 years in the future be too late?

No matter what you choose, build stuff and be around smart people.

For most of the early hires you make in a startup, experience doesn't matter very much, and you should go for aptitude.
