Starting a company has always involved making critical decisions with imperfect information. From running board meetings and raising money to building amazing products that people will love (even if they don’t know it yet), founders have to master a breathtaking array of domains in an incredibly short amount of time. Even repeat founders consistently face unforeseen challenges. But this notion of forging ahead without all the answers has rarely felt more apt. With a future that’s more cloudy than clear, these increasingly unmooring circumstances are the ultimate test of a leader’s resilience.
