Entrepreneur-turned-educator Steve Blank the father of modern entrepreneurship. Credited with launching the Lean Startup movement, he’s changed how startups are built; how entrepreneurship is taught; how science is commercialized, and how companies and the government innovate. Steve is the author of The Four Steps to the Epiphany, The Startup Owner’s Manual -- and his May 2013 Harvard Business Review cover story defined the Lean Startup movement. He teaches at Stanford and Berkeley, and is the Senior Fellow For Entrepreneurship at Columbia University. He created the National Science Foundation Innovation Corps -- now the standard for science commercialization in the U.S. His Hacking for Defense class at Stanford is revolutionizing how the U.S. defense and intelligence community can deploy innovation with speed and urgency. The class is one of several sister courses -- including Hacking for Diplomacy, Hacking for Energy and Hacking for Impact -- that represent a new platform for national service.
