The Lean Startup

Quick Review

Eric Ries codified what many successful founders learned the hard way: build, measure, learn, repeat. The core insight is simple but profound: most startups fail not because they can't build a product, but because they build something nobody wants. The solution? Validated learning through rapid experimentation. The MVP (Minimum Viable Product) concept has been overused and misunderstood since this book, but Ries's original formulation is spot-on: build the smallest thing that lets you start learning. My favorite chapters focus on pivot vs. persevere decisions. Knowing when to change course is an art, and Ries provides frameworks to make that call more scientific. If I have one criticism, it's that the book can feel repetitive. The key concepts could have been compressed. But for anyone building a product, this is required reading.
