The Lean Startup

The Lean Startup is a business and innovation approach popularized by Eric Ries that focuses on building companies and products efficiently by reducing waste and uncertainty. Instead of spending years developing a perfect product, it encourages entrepreneurs to quickly create a Minimum Viable Product (MVP), test it with real customers, and learn from feedback. The core cycle—Build → Measure → Learn—helps teams validate ideas using data rather than assumptions. Based on what they learn, they either persevere with the strategy or pivot to a new direction. The goal is validated learning, faster innovation, and creating products that truly meet customer needs, especially in uncertain and fast-changing markets.
