Hook
Your mom will always tell you your business idea is great. That’s why most customer interviews are worthless. Rob Fitzpatrick wrote the definitive guide to getting honest feedback before you build something nobody wants.
What It’s About
The Mom Test addresses one of the most common startup failures: building products based on misleading customer feedback. The rules: talk about their life instead of your idea, ask about past specifics instead of future hypotheticals, talk less and listen more, and focus on problems not solutions.
At 130 pages of pure signal — no filler, no padding. The frameworks apply well beyond startups to product management, design, consulting, and anyone who needs accurate information.
Key Takeaways
The shift from “Would you buy this?” to “Tell me about the last time you dealt with this problem” is the single most important technique. Past behavior is the best predictor of future behavior. Fitzpatrick’s “commitment and advancement” concept is also crucial — after every conversation, get a concrete commitment, not just encouraging words.
The Verdict
The single best book on customer discovery. Short, practical, and packed with immediately usable techniques. If you’re building anything for other people, this book will save you from expensive mistakes.
