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

Whatever the founder cares about, whatever the founders think are the key goals, that's going to be what the whole company focusses on.

You think you have this great idea that everyone's going to come join, but that's not how it works.

Here's a good rule of thumb: don't worry about a competitor at all, until they're actually beating you with a real shipped product.

Share results (financial and key metrics) with the company every month.

The most important thing is that there is clear reporting structure and everyone knows what it is.

It's easy to move fast or be obsessed with quality, but the trick is you have to do both at a startup.
