LEANSpark

LEANSpark is an AI coach that turns your startup idea into a Lean Canvas and stress-tests it across seven business model dimensions, giving a verdict and prioritized fixes. Built by Lean Canvas creator Ash Maurya, it offers a free full check plus paid plans for validation and growth.

LEANSpark is an AI coaching tool for early-stage founders who need a clear verdict on whether their business idea is worth pursuing. Built by Ash Maurya, the creator of Lean Canvas, it applies the Continuous Innovation Framework to run a structured stress test across seven dimensions of a business model. The product is aimed at solo founders, small teams, and cohort programs such as accelerators and university entrepreneurship classes. It works from a plain-language description of your idea: you do not need a pitch deck, a business plan, or prior knowledge of Lean Canvas. In practice, LEANSpark turns your idea into a Lean Canvas and then tests it. It can also import a canvas from an existing landing page. The stress test produces a plain verdict on each of the seven dimensions, with specific fixes prioritized. A free Business Model Check includes the full stress test, a report, one re-test per test, and ten coach replies. Paid plans add ongoing testing and fixing (Starter at $25 per month), help with demand validation through interview planning and transcript analysis (Pro at $50 per month), and growth experiments tied to your numbers (Power at $100 per month). The same plan, test, check, decide loop runs at every tier. The tool is transparent about outcomes: 58 percent of stress tests fail, which the team frames as the point, since a scorecard that always passes would be useless. Live product counters show thousands of founders, ideas, and stress tests across more than 138 countries and 32 languages. For organizations, schools and accelerators get a dashboard to coach every founder rather than only the most vocal ones. LEANSpark sits alongside general-purpose chat assistants by offering continuity and a specific methodology, and it complements tools like spreadsheets or canvas templates by adding active analysis and next-step recommendations.
