The Lean Startup is a methodology designed to help entrepreneurs develop businesses and products more efficiently. It emphasizes rapid prototyping, validated learning, and iterative product releases to minimize waste and maximize customer feedback. By focusing on what customers actually want, startups can avoid building products that do not meet market needs. The approach encourages the use of a Build-Measure-Learn feedback loop, where ideas are quickly turned into prototypes, tested in the market, and refined based on real user data. This cycle helps startups adapt and pivot their strategies, ultimately increasing their chances of success in a competitive landscape.
