Lean Customer Development – Build Products People Actually Want

Book Summary

In Lean Customer Development, product strategist Cindy Alvarez challenges the risky habit of building products based on gut instinct or assumptions. Instead, she offers a proven, step-by-step guide to identifying what customers really need—before you start building. By combining real customer interviews with lean principles, this book helps entrepreneurs and product teams validate ideas early, reduce waste, and deliver value faster. It’s not about guessing—it’s about discovering. Whether you’re in a startup or a large enterprise, Alvarez’s method helps you build with confidence, not hope.
