Entrepreneur Steve Blank has served as a founder, investor and even in the air force. But there’s another title he’s is known for: professor.

Blank has earned a reputation among budding and veteran business leaders alike as the father of the Lean Startup movement, a business philosophy that popularized startup concepts like “pivoting” and “minimum viable product.” And he’s taught these ideas on business and innovation at Stanford, the University of California at Berkeley, Columbia and New York Universities. His course on the “lean” methodologies, called Lean Launchpad, is offered at more than 75 schools around the world and was one of the earliest to appear on the online course platform Udacity.

This week on the EdSurge On Air podcast, we talk to Steve about both his business and teaching careers, and how changes in the startup world are reflected in both the lean method and his courses.

Highlights from the conversation below have been lightly edited and condensed for clarity.
