A single mediocre hire in the first five will often in fact kill a startup.

Don't let the company get distracted or excited about other things. A common mistake is that companies get excited by their own PR.

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

At the beginning, you should only hire when you have a desperate need to.

If you ever take your foot off the gas pedal, things will spiral out of control, snowball downwards.

More important than starting any startup, is getting to know a lot of potential co-founders.

The tenth social network, and limited only to college students with no money, also terrible. Myspace had won.
