> I feel like I remember PG telling me that large founding teams (more than 3) were highly correlated with failure.

They usually are, but the median is not the message. If it's a group of college friends coming together to start a company for the first time, 2-3 people is way better than 4-5. But if you've worked with a few people before, know them well, and know how to set up expectations on day one, you can successfully have a larger group of cofounders without worrying about conflict. (This is something I've discovered for myself, it doesn't mean it would work for everyone)

At 4 or 5 founders, it hinges on group dynamics, not just the individual personalities of the founders. You need excellent communication, clear commitment, and you absolutely need two characters in the mix:

- A "negotiator". The kind of personality that is always mending the cracks that inevitably appear in the group.

- A visionary. The kind of personality that is incredibly optimist and always has the destination and the path in view.

Smaller groups can forfeit these needs and function, and are thus easier to assemble.

I've never seen groups larger than five succeed, and I've seen quite a few fail.
