They say you shouldn't ask your mom whether your business is a good idea, because she loves you and will lie to you. This is technically true, but it misses the point. You shouldn't ask anyone if your business is a good idea. It's a bad question and everyone will lie to you at least a little . As a matter of fact, it's not their responsibility to tell you the truth. It's your responsibility to find it and it's worth doing right . Talking to customers is one of the foundational skills of both Customer Development and Lean Startup. We all know we're supposed to do it, but nobody seems willing to admit that it's easy to screw up and hard to do right. This book is going to show you how customer conversations go wrong and how you can do better. Review: Changed the way I approach customer conversations - This book is short, sharp, and absolutely packed with practical advice. It helped me recognize how much I was unintentionally biasing conversations with potential customers just by asking the wrong kinds of questions. What makes it stand out is how specific and actionable the examples are. It doesn’t waste time with fluff... it shows you exactly what to say and what to avoid if you want honest, useful feedback. I’ve applied its principles in real conversations, and the difference in the responses has been huge. A must-read for anyone testing or building a product. Review: This book can save you billions of dollars (and make billions as well) - A billion dollars? Yeah. First about me: I've spent the last three years applying the tools of human-centric design to business projects. I'm also thoroughly trained in the scientific method. This book is WILL save you billions. And if you have great ideas, you can make billions, too. In science, we know that proving a hypothesis does not provide one with strong evidence. It's primarily a matter of picking the right kind of evidence.(Often how a case is made in court.) The strongest kind of evidence is falsifying a hypothesis. Everything points in one direction, making something highly probable. But you might be wrong. You need to look for that one piece of evidence that shows you're wrong, even if everything else seems to support it. It took me a while to truly understand the significance of that. You don't have to, if you read The Mom Test, but you will benefit from what it means in practical know-how when you talk to customers. (And they are the ones who will, or will not, open their wallets.) Fitzpatrick shows you the questions we tend to ask - and we learn to identify which ones are extremely bad to ask. They are making our interviewees partners in crime of confirming something which simply isn't true. Every practical piece of advice in this book is highly valuable; one favorite of mine is to make sure you don't zoom in too early. You can get someone get highly emotional about a problem. Yet, if this is a lower-level problem, that the customer has never bothered to take action to change, it's still not a big problem for you to solve. Obvious, yes. This whole book is obvious. And yet, it's funny how often the most obvious stuff is ignored when it really counts. Don't mistake the laid-back-style of writing with its importance. Usually it takes years of practical experience to learn from mistakes, that will make you correctly apply an important theory that you grasp, into successful practical application.This book gives you that in - what, an hour of enjoyable reading? I've read many books on customer research. This books is invaluable. Read this one and you will probably go crazy when observing even more seasoned customer researchers for the traps they're stepping into, unknowingly, potentially wasting lots and lots of resources towards the wrong pursuit.

It was very annoying to have to go back over sentences, confused, only to realize there are terrible typos and grammatical errors throughout. ## Frequently Bought Together - The Mom Test: How to talk to customers & learn if your business is a good idea when everyone is lying to you - The Lean Startup: How Today's Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses - Crossing the Chasm, 3rd Edition: Marketing and Selling Disruptive Products to Mainstream Customers (Collins Business Essentials) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/31713157-the-mom-test-how-to-talk-to-customers-and-learn](https://www.desertcart.pt/products/31713157-the-mom-test-how-to-talk-to-customers-and-learn) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-11-13*
