The thing that kills startups at some level, is the founders giving up.

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 biggest PR hack you can do, is not hire a PR firm.

One of the pieces of advice that we give at YC is: try to work together on a project rather than just doing an interview.

To get the very best people- they have a lot of great options, and so it can easily take a year to recruit someone.

Every thing at a startup gets modeled after the founders. Whatever the founders do becomes the culture.

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