One of the books I reread periodically and recommend to idea-stage founders is The Mom Test. It’s a short read and can add tremendous value to founders who are thinking about what solution they should build or what problem they want to solve. Every founder I’ve recommended the book to, and who read it, loved it.

The book focuses on a single topic: customer discovery. It outlines a simple, effective methodology for talking with customers. The book details how to ask the right questions (that aren’t leading questions) so conversations yield valuable insights about customer pain and its severity. The book does a good job of laying out an approach that helps founders better understand what (if anything) they should build, which can prevent founders from wasting time, energy, and money. Another reason I like this book for idea-stage founders is that it helps them avoid the common solution-in-search-of-a-problem trap.

If you’re an early-stage founder who hasn’t found product–market fit yet, consider giving the book a read.
