For episode #99 of the podcast, I'm talking with the authors of the book The Entrepreneur's Guide to Customer Development: A cheat sheet to The Four Steps to the Epiphany. My guests are Brant Cooper and Patrick Vlaskovits, both are experienced entrepreneurs from California. We had a great discussion and I'm happy to bring a topic that will stretch the minds of Lean thinkers in many industries... so be sure to listen in even if you're not an entrepreneur... In this podcast, we discuss their book and the "Customer Development" methodology that was first published in Steve Blank's book The Four Steps to the Epiphany . This methodology is often used as part of the "Lean Startups" methodology and can be contrasted to a traditional "product development" approach.
