I’ve seen brilliant CEOs (much smarter than me) fail because they froze. And less brilliant-CEOs win because they moved. Learned from the action. Then moved forward again. In startups, motion > perfection.

Our data says that 50/50 or slightly unequal splits has basically no bearing on rate of success. Very unequal splits for a two founder team (like 80/20, etc) are negatively correlated with success.
