Lean Canvas

Metadata

Name: lean-canvas
Description: Generate a Lean Canvas business model with detailed sections for problem, solution, metrics, cost structure, UVP, unfair advantage, channels, segments, and revenue.
Triggers: lean canvas, startup canvas, lean model, business hypothesis

Instructions

You are a business model strategist designing a Lean Canvas for $ARGUMENTS.

Your task is to create a comprehensive Lean Canvas that outlines the business hypothesis and key business model assumptions for the product.

Input Requirements

Product or feature description
Target customer segment(s)
Market context and problem space
Any available metrics or business constraints

Lean Canvas Template

Section 1: Product Definition

1. Problem

Top 3 customer problems or needs
Customer pains and frustrations
Current unsatisfactory solutions

2. Solution

Top 3 features or approaches
How each feature addresses the problem
Why this solution is novel or better

3. Unique Value Proposition (UVP)

Concise, memorable statement
Why customers choose you over alternatives
What makes you different (not just "better")

4. Unfair Advantage

What defensibility exists?
Barriers to competition (network effects, brand, IP, switching costs)
What competitors can't easily replicate

Section 2: Market & Traction

5. Customer Segments

Who is the target customer?
Early adopters and first segment
Customer personas or archetypes
How large is the addressable market?

6. Channels

How do you reach customers?
Primary acquisition channels
Distribution and sales approach
How do customers find you?

7. Revenue Streams

How do you make money?
Pricing model or revenue per customer
Customer lifetime value (LTV)
Revenue growth assumptions

Section 3: Economics & Validation

8. Cost Structure

Fixed costs (salaries, infrastructure, facilities)
Variable costs (COGS, transaction costs, support)
Key cost drivers
Cost per customer acquisition (CAC)

9. Key Metrics

Activation: How do users get value quickly?
Retention: How many users stick around?
Revenue: How do we measure financial success?
North Star metric for the business

Output Process

Define the core problem(s) being solved
Outline 2-3 solution approaches
Craft a compelling UVP
Identify what creates competitive advantage
Target 1-2 customer segments
Map acquisition channels
Define revenue model and pricing
Estimate cost structure
Identify 3-5 critical metrics to track
Surface key assumptions and hypotheses
Suggest validation experiments (landing page, interviews, MVP)

Domain Context

Lean Canvas vs Business Model Canvas vs Startup Canvas:

Lean Canvas (Ash Maurya) is a startup-focused adaptation of the Business Model Canvas that replaces Partners/Activities/Resources with Problem/Solution/Unfair Advantage. It's fast and hypothesis-driven, but has known limitations:

Redundancy: "Problem" overlaps with Market Segments (markets are defined by problems/JTBD), and "Solution" overlaps with Value Proposition (which by definition includes features). This can create confusion about what goes where.
Missing strategic sections: No vision (why should your team wake up every day?), no trade-offs (what you choose NOT to do), no relative costs (low cost vs unique value positioning), no key metrics.
Narrow defensibility: "Unfair Advantage" focuses on one defensive element, but strong strategy is hard to copy as an integrated whole — not because of a single advantage.
No coherence check: Doesn't address whether all strategic choices reinforce each other.

When to use Lean Canvas: Quick hypothesis testing when you need speed over completeness. Best as a brainstorming tool, not a strategy document.

Consider instead: Startup Canvas (Paweł Huryn) separates strategy (9 sections from the Product Strategy Canvas) from business model (Cost Structure + Revenue Streams). Recommended when you need both strategic clarity AND a business model for a new product.

Notes

The Lean Canvas is designed for rapid hypothesis testing
Focus on addressing the riskiest assumptions first
Update the canvas as you learn and validate
Each section should be specific and measurable where possible
This canvas helps align founding teams on business strategy
