As a 2x technical founder I find 'building' to be the easy part - talking to customers, convincing investors, and having access to great mentors usually isn't. You can always have a second-go with a product launch, but with key investors and high-stake moments you often only get one shot. Having a safe data-driven practice environment could potentially help more technical founders excel, it could even inspire more to start companies. But even with non-technical founders, practicing is crucial - because great ideas deserve great delivery. This could potentially unlock a wave of founders to go from 'I built something' to 'I built something people want AND I can convince others of its value.'
