Steve Blank is known by some as “The Startup Whisperer" -- the guy that entrepreneurs turn to when they have questions about how to start or energize their business. He is also a serial entrepreneur, professor and investor who is perhaps best known for his books Four Steps to the Epiphany and The Startup Owner's Manual. Last week Steve stopped by our studio to cast his experienced and critical eye on the business of edtech. In a wide-ranging chat with EdSurge CEO Betsy Corcoran, Steve talks about about the history of Silicon Valley, edtech’s commercialization problem, and whether entrepreneurship in edtech is really any different than regular tech.
