Prototype costs buried your startup. Test cheap assumptions before building anything

Your team just spent three months building a feature nobody wants. The burn rate is real, the revenue is not. You need a system that kills bad ideas before they drain your runway. The Lean Startup method replaces guesswork with a Build-Measure-Learn loop. You will learn to create Minimum Viable Products that test core assumptions in days, not months, and use validated learning to pivot or persevere with confidence. This book gives you the framework to turn customer feedback into a product roadmap that actually works.
No more funding features that fail. No more building in the dark. Stop treating your prototype as truth. Let your customers reveal the real path forward before your budget runs out.
