I’m Jim Semick — a founder, lecturer, and product discovery practitioner. Over the past 25 years, I’ve helped validate and launch products used by millions of people, co-founded a product management software company (acquired 2022), and now teach the next generation of entrepreneurs how to test their ideas before they build. These days, I spend my time writing, teaching at UC Santa Barbara, mentoring founders, and working on a book about the craft of validating business models.
