A lot of people ask me what the ideal cofounder looks like. I now have an answer: Greg Brockman.
Every successful startup I know has at least one person who provides the force of will to make the startup happen. I’d thought a lot about this in the abstract while advising YC startups, but until OpenAI I hadn’t observed up close someone else drive the formation of a startup.
OpenAI wouldn’t have happened without Greg. He commits quickly and fully to things. I organized a group dinner early on to talk about what such an organization might look like, and drove him home afterwards. Greg asked me questions for the first half of the drive back to San Francisco, then declared he was in, and started planning logistics for the rest of the drive.
