I first read Steve Blank’s The Four Steps to the Epiphany where I discovered his powerful concept of “customer development.”
His latest book The Startup Owner’s Manual: The Step-By-Step Guide for Building a Great Company is also highly recommended.
Beyond his books, Steve has created a very well curated site of resources for entrepreneurs that is well worth your time to explore and consume.
Steve is a successful serial entrepreneur, writer, lecturer and startup guru. I only wish he was headquartered here in Boston, rather than in Silicon Valley. But you can take advantage of his practical wisdom by reading his books, watching his videos and following his recommended path.
