About the author
Rob Fitzpatrick is a British entrepreneur and writer whose practical books address customer interviews, early sales, workshops, and the problems founders create when they ask people to evaluate an idea politely.
The Mom Test is his best-known book and turns customer discovery into a short set of conversational rules. No dedicated Wikipedia identity page is available, so the external link provides context on customer development.
