Jason Evanish gave a presentation on Lean Startups and how to apply Lean principles to new ventures. He discussed that Lean Startups focus on getting customer feedback as early as possible through interviews and minimum viable products, rapidly iterating based on what is learned. Evanish recommended tools like the Lean Canvas and customer development interviews to help follow the Lean process and identify problems to solve rather than features to build. He closed by urging attendees to start applying Lean Startup techniques immediately and provided further resources on the topic.
