Classic post by @naval @nivi of @angellist on why picking a co-founder is your most important decision when starting a company. It’s more important than your product, market, and investors. The ideal founding team is two individuals, with a history of working together, of similar age and financial standing, with mutual respect. One is good at building products and the other is good at selling them. Think Jobs and Wozniak, Allen and Gates, Ellison and Lane, Hewlett and Packard, Larry and Sergei, Yang and Filo, Omidyar and Skoll.
