The Lean Canvas is a 1-page business model framework created by Ash Maurya, adapted from the Business Model Canvas. It captures the 9 elements that matter most for an early-stage startup: problem, customer segments, unique value proposition, solution, channels, revenue streams, cost structure, key metrics and unfair advantage.
The Lean Canvas (Maurya) is built for early-stage startups still validating the problem — it includes blocks for problem, solution, key metrics and unfair advantage. The Business Model Canvas (Osterwalder) is broader and better suited to established companies or scaling models — it covers partners, resources and activities. Use the Lean Canvas while you're searching for product-market fit; use the Business Model Canvas Generator once your model is taking shape.
Your idea is sent to OpenAI only for the generation step and is not stored. The generated canvas lives only in your browser — we do not save it on our servers. No human reads it.
Yes. Each section is editable inline — click a section, tweak the content, and your changes are kept until you reset the canvas or close the tab.
Yes. Use the Print button to print on paper or save the canvas as a PDF (choose "Save as PDF" in your browser's print dialog). The layout is optimized for A4 landscape.
Typically 30 to 60 seconds. Please don't close the page during generation.
The free tool gives you a clean first draft to start iterating on. The SeedAngels app goes further: it grounds each section with web research, runs a quality reviewer, and links the canvas to your market analysis, financial forecast, business plan and pitch deck.
