Our focus is to teach entrepreneurs the process of validating business ideas through hands-on experimentation and mentorship. Three days is an extremely short amount of time, but it’s enough to test multiple business concepts, identify which one has the most potential, and even collect money from customers. While Lean Startup Machine and Startup Weekend share the same spirit of experiential learning over a few days, Lean Startup Machine emphasizes validating ideas before building. Some view Lean Startup Machine as the step before Startup Weekend.
