Lean Canvas

Lean Canvas is a 1-page business model template designed for startups operating under extreme uncertainty. Created by Ash Maurya in 2010, it adapts Alexander Osterwalder's Business Model Canvas to focus on identifying and testing riskiest assumptions early. The tool replaces four traditional boxes with startup-specific ones: Problem, Solution, Key Metrics, and Unfair Advantage. Used by over 1 million entrepreneurs worldwide, Lean Canvas is a core component of the Running Lean methodology. LEANSpark, the AI-powered version, helps founders build and stress-test their canvas in plain English, providing a clear validation plan in under 5 minutes.
