The Lean Startup introduced a revolutionary approach to how modern companies are built. Instead of following traditional business plans, Eric Ries proposes a scientific method for creating and managing successful startups in an age where innovation speed defines survival. This methodology centers around rapid experimentation, validated learning, and iterative product development — helping founders focus on what customers truly need. Through concepts like the Minimum Viable Product (MVP) and pivot vs. persevere decisions, teams can adapt quickly and avoid wasting resources on unwanted features. Ries’s background as an engineer and entrepreneur brings both technical precision and practical experience. He shares lessons from his own startup journey, giving readers a clear path from idea to sustainable growth. Read this book early in your startup journey or when your product is in early traction stages. It’s especially powerful for developers and small teams working on MVPs or refining product-market fit.
