Lean Canvas
In one sentence
A one-page startup plan that starts with the problem, not the product.
The simple version
Ash Maurya adapted the Business Model Canvas for startups. You fill in nine boxes, starting with the customer's problem and finishing with your 'unfair advantage'. It takes 20 minutes and shows you which guesses are riskiest.
Problem
Top 3 pains
Solution
Simplest fix
Unique value
One clear promise
Unfair advantage
Hard to copy
Customers
Who & early adopters
Key metrics
Numbers that matter
Channels
Path to customers
Costs
What you spend
Revenue
How you earn
Why it matters
It turns a fuzzy idea into a list of testable assumptions you can update every week.
How to do it
- 1Problem: top 3 problems.
- 2Customer segments: who has them? Who are early adopters?
- 3Unique value proposition: one clear sentence.
- 4Solution: simplest fix for each problem.
- 5Channels, revenue, costs.
- 6Key metrics: the numbers that matter.
- 7Unfair advantage: something that can't easily be copied.
- 8Mark the riskiest box and test it first.
Real-world example
A pet-sitting idea's canvas shows the riskiest box is 'Will owners trust strangers?' — so the first test is trust, not the app.
What the books say
Start with the problem. Most ideas fail because they solve a problem nobody cares enough about.
“Life's too short to build something nobody wants.”
Common mistakes
- Filling 'unfair advantage' with 'passion'.
- Writing solutions before problems.
- Never revisiting it.
Questions people ask
How often should I update it?
Whenever you learn something big — many founders review it weekly early on.
