Lean Canvas

You're planning a new product or venture. The business plan is growing but the confidence isn't. The team keeps adding detail to avoid confronting what they don't actually know.

Lean Canvas is Ash Maurya's adaptation of the Business Model Canvas, tuned for startups and new ventures. You fill a single page covering Problem, Solution, Key Metrics, Unfair Advantage, and five other blocks — documenting the riskiest assumptions rather than building a polished plan.
