What is lean startup methodology?

Lean startup methodology emphasizes building, measuring, and learning quickly to validate business ideas with minimal resources. Key concepts include building MVPs (Minimum Viable Products), testing hypotheses with real customers, pivoting based on learning, and focusing on validated learning over assumptions. It's about learning what customers want quickly and cheaply, then building that. Avoid building features nobody wants. Example: A startup used lean methodology to test a product idea with a simple landing page and email signup, validating demand before building the full product, saving months of development time.
