The customer development methodology created by Steve Blank redefined how new ventures transition from untested hypotheses to established market entities. By emphasizing that facts regarding a business model reside outside the office, he established the core principles of the lean startup movement, fundamentally altering the traditional business school approach of relying on standard planning documents.
Early Life and Military Service
Born in 1953 in the Lower East Side of New York City to Jewish immigrant parents, Blank attended Martin Van Buren High School and spent one semester at the University of Michigan. His career began with four years of service in the U.S. Air Force during the Vietnam War. Stationed in Thailand, he maintained electronic intelligence and warfare systems on A-7, F-4, and F-105G aircraft, later supporting B-52 bombers in Oscoda, Michigan.
