Lean Canvas

Reference model

The Lean CanvasNine boxes on one page. Across the top: problem (with existing alternatives), solution with key metrics beneath it, unique value proposition (with the high-level concept), unfair advantage with channels beneath it, and customer segments (with early adopters). Cost structure and revenue streams run along the bottom.ProblemThe top 1–3 problemsthe customer has.Existingalternatives: howthey cope today.SolutionThe top threefeatures that answerthe problems.Key metricsThe few numbers thatshow how you aredoing.Unique valuepropositionA single, clear,compelling messagethat says why youare different andworth buying.High-level concept:“X for Y”.UnfairadvantageSomething thatcannot easily becopied or bought.ChannelsThe path tocustomers.CustomersegmentsWho has the problem:the targetcustomers.Early adopters: whowould try it first.Cost structureCustomer acquisition, delivery, people and premises.Revenue streamsHow you will earn: price, margin and lifetime value.

Start with the problem and the customer on the left and right; the value proposition sits in the middle; the money runs along the bottom.

About this model

A one-page plan for an idea that does not yet have a business. It swaps the Business Model Canvas’s partners, activities, resources and relationships for the things a new venture must prove first: the problem, the solution, the key metrics and the unfair advantage.

Ash Maurya — Running Lean (adapted from the Business Model Canvas) · 2010

How to read it

  • Fill it in quickly, in this order: problem, customer segments, unique value proposition, solution, channels, revenue streams, cost structure, key metrics, unfair advantage. Keep each box to what you actually know.
  • The problem and the customer are the riskiest parts: most new ventures fail by building a solution for a problem nobody has. Name the early adopters, not “everyone”.
  • Treat every box as a hypothesis. Pick the riskiest assumption and design the cheapest test of it before you build anything.

What this does

Sketches a one-page business model for an idea that doesn't have a business yet — problem, solution, key metrics, unfair advantage — before committing to the full Business Model Canvas.

When to use it

Ideation and very early Startup, testing a new idea before there's a proven customer or revenue line to model.

Not when: Once the business has paying customers and a repeatable model — move to the Business Model Canvas, which captures partners, channels and cost structure this canvas deliberately leaves out.

What happens next

A validated canvas graduates into the full Business Model Canvas once there is a real customer segment and revenue line to build the other blocks around.
