"I co-wrote another essay with Charlie Songhurst: "Mispriced Talent" Founders think they can find mispriced talent. Its important to be aware of how youre finding mispriced talent so that you dont deceive yourself. There are two main ways to beat the market. 1) Pay in effort 2) Pay in uncertainty Paying in effort is well suited for high conscientiousness founders. Youre willing to do the slog. This might mean working hard to get to know every person in a given role in your city. Paying in uncertainty is well suited for high chaos founders. Youre willing to endure low status for a long time."
