Many of the best YC companies have had phenomenally small number of employees for their first year, sometimes none besides the founders.

Because it's one of these sort of connections between nodes- every pair of people adds communication overhead.

I prefer to invest in a company that's going after a small but rapidly growing market than a big but slow growing one.

When it comes to starting startups, in many ways, it's easier to start a hard startup than an easy startup.

For most software startups, this translates to keep growing. For hardware startups, it translates to don't let your ship date slip.

So always keep momentum, it's this prime directive for managing a startup.

The track record for founders that don't already know each other is really bad.
