TL;DR equal shares in the same layers and vesting are the big points.

For the top layer: the real nature of a person comes out when they have a perceived opportunity to win big at someone's expense... hence good friends can make good cofounders. Failing that, find someone that plays well with others and considers the long-game of their actions. (You're gonna stick together for the next venture if this app doesn't work out, right?)

For the second layer: should be people you'd like to work with that may be founders in the future or people that have been recommended.

Third layer are more/less startup employees. So not regular corporate like employees that need to be thought for or are super niche, but T-shaped folks that can take initiative and worry a little more about details.
