The Lean Canvas: Your Whole Business Plan on One Page
Long business plans are slow to write and quickly outdated. The Lean Canvas captures your idea in nine boxes and helps you spot weak points fast.
A traditional business plan can run to 40 pages, and by the time you finish it, your assumptions may already have changed. The Lean Canvas, created by Ash Maurya as an adaptation of Alexander Osterwalder's Business Model Canvas, fits your whole idea on a single page.
Why use it
- It is fast. You can sketch one in about 20 minutes.
- It shows gaps. Empty or fuzzy boxes show what you do not know yet.
- It is easy to share and change. Update it as you learn.
- It focuses on problems and customers, not on lengthy descriptions.
The nine boxes, step by step
Problem
List the top three problems your customers face. Also note how they handle them today.
Customer segments
Who exactly has these problems? Be specific, such as "working parents in Pune who cook on weekdays".
Unique value proposition
One clear, compelling sentence on why you are different and worth attention.
Solution
The simplest features that address each problem.
Channels
How will you reach customers: word of mouth, social media, partnerships, search, or local events?
Revenue streams
How will you make money, and at what price?
Cost structure
Your main costs, fixed and variable.
Key metrics
The few numbers that show progress, such as sign-ups, repeat orders, or monthly revenue.
Unfair advantage
Something that cannot easily be copied: a special skill, a community, exclusive access, or years of experience. If you do not have one yet, leave it blank honestly.
A quick example: a weekly tiffin service
- Problem: Office workers have no time to cook, and outside food is unhealthy.
- Customer: Single professionals near IT parks.
- Value proposition: Fresh home-style meals delivered to your desk by 12:30.
- Solution: Weekly subscription with a simple menu.
- Channels: Office WhatsApp groups, local societies.
- Revenue: ₹150 per meal, weekly prepaid plans.
- Costs: Ingredients, cook wages, packaging, delivery.
- Metrics: Subscribers, renewal rate, cost per meal.
- Advantage: A skilled cook with a loyal neighbourhood following.
How to use it well
Fill it fast
Do not overthink. Write your best guesses in 20 minutes.
Mark the riskiest box
Which assumption would sink you if wrong? Often it is the problem or customer.
Test that box first
Talk to customers or run a small experiment.
Update and repeat
Cross out what is wrong, and write what you learned.
Make one canvas per customer type
Different customers may need different value propositions.
What most people miss
- Specific beats broad. "Everyone" is not a customer segment.
- Price is a hypothesis too. Test it. Many founders underprice.
- It is a living document. Revisit it every month or so.
