About

Hello there! I’m a general partner at Andreessen Horowitz focused on tech startups, and I’m based between LA and SF.

I write a newsletter with long-form essays on startups, user growth, and network effects — I’ve written over 650+ essays, which are now archived here.

If you want more, I’ve written The Cold Start Problem, a best-selling book on how to launch startups, achieve growth, and grow network effects.
