Bob Dorf is likely the second most knowledgeable Lean and Customer Development expert on the planet, second only to Steve Blank, who developed the methodology and spent a decade extending and refining it. Together with Steve Blank, Bob published The Startup Owner's Manual: The Step-by-Step Guide for Building a Great Company. Today, after two years of near-fulltime research and writing, it's Amazon.com's #1 Business/Entrepreneurship bestseller, published in 15 languages worldwide. The 608-page, painstakingly detailed guide is the most comprehensive, rigorous step-by-step roadmap available anywhere, guiding startup founders throughout the world. Bob Dorf travels the world, helping startups, foreign governments, and major corporations learn how to effectively deploy Customer Development process through intensive 8-10 week training sessions, as well as one- and two-day workshops and hands-on consulting that he conducts repeatedly in Russia, Latin America, and throughout the US. He teaches the Lean LaunchPad program at Columbia Business School, where he is an Adjunct Professor of Entrepreneurship, and has led training sessions at Tech de Monterrey, Mexico, Skolkovo Business School in Moscow, and repeatedly for the government of Colombia and Moscow's GVA Launch Gurus "Startup Academy."Entrepreneurial from the age of 12, Bob received his last W-2 some 40 years ago, when he left a great news editor's job at WINS Radio in New York to launch his first major startup. Since then, he has personally founded seven companies, including--as he puts it--"two homeruns, two base hits, and three solid tax losses."
