The Lean Canvas is a strategic tool designed for startups and entrepreneurs to outline their business model on a single page. It helps visualize key components such as the problem being solved, target customer segments, unique value propositions, and revenue streams. This framework encourages quick iterations and adjustments based on feedback and market conditions. Developed by Ash Maurya, the Lean Canvas is an adaptation of the traditional Business Model Canvas. It emphasizes a problem-solution fit, making it particularly useful for early-stage ventures. By focusing on essential elements, it aids in identifying risks and opportunities, streamlining the path to a viable business model.
