Before product/market fit, your only job that matters is to build a great product.
Developing a personal connection with anyone you're trying to do a big deal with is really important.
Employees will only add more value over time.
Obsess about the quality of the product.
You need someone that behaves like James Bond more than you need someone that is an expert in some particular domain.
So you should always stay on top of people's vesting schedules.
