You can create value with breakthrough innovation, incremental refinement, or complex coordination. Great companies often do two of these. The very best companies do all three.

The best source by far for hiring is people that you already know and people that other employees in the company already know.

Just put a little pin in your mind: when you cross 50 employees, there are a new set of HR rules that you have to comply with.

If you're not in college and you don't know a cofounder, the next best thing I think is to go work at an interesting company.

I believe in fighting with investors to reduce the amount of equity they get and then being as generous as you possibly can with employees.

You have to be decisive. Indecisiveness is a startup killer.

... but actually it sucks to have a lot of employees, and you should be proud of how few employees you have.
