The Lean Startup Machine is a metrics-driven process that allows founders to test their ideas against reality, and it was found to be useful for those building real, working prototypes. The teams that participated in the event were able to make significant advancements in their business strategy and product design before even building a product, with continuous and focused customer input. Through iterative testing and experimentation, these teams discovered what worked and what didn't, and were better poised to build their products with customer feedback. The event was highly educational and provided valuable insights for founders and mentors alike, and it's possible that Lean Startup Machine will come to other cities in the future.
