Business Model Canvas & Lean Canvas
Purpose: lay out a whole business model on one page to stress-test its coherence before committing strategy or capital. Two related one-pagers live here:
- Business Model Canvas (BMC) — Osterwalder/Strategyzer, 9 blocks, for established or multi-stakeholder businesses.
- Lean Canvas — Ash Maurya's startup adaptation of the BMC, 9 blocks, optimized for early-stage problem/risk discovery.
Use these for business-model design, pivot evaluation, or as the zoom-out companion when
spark's Value Proposition Canvas has settled customer-fit but the whole-business fit
is unproven.
Not the same as the Strategy Canvas. The Blue Ocean "Strategy Canvas / Value Curve" in
blue-ocean-strategy.mdplots competition factors to find uncontested space — a competitive positioning tool. The BMC/Lean Canvas describe how one business creates, delivers, and captures value. Keep them distinct.

Business Model Canvas — 9 Blocks
| # | Block | Question |
|---|---|---|
| 1 | Customer Segments |
Who are we creating value for? Who are the most important customers? |
| 2 | Value Propositions |
What value do we deliver? Which problem/job do we solve? (zoom-in → VPC) |
| 3 | Channels |
How do segments want to be reached and served? |
| 4 | Customer Relationships |
What relationship does each segment expect (self-serve, dedicated, community)? |
| 5 | Revenue Streams |
For what value are customers willing to pay? Pricing mechanism? |
| 6 | Key Resources |
What assets does the value proposition require (physical, IP, human, financial)? |
| 7 | Key Activities |
What must we do well to deliver (production, platform, problem-solving)? |
| 8 | Key Partnerships |
Who are our key suppliers/partners? What do we source vs build? |
| 9 | Cost Structure |
What are the dominant costs? Cost-driven vs value-driven? |
Fill order: right side first (1→5, the value/market side), then left side (6→9, the infrastructure/cost side). The two sides must balance — Revenue Streams (5) must plausibly exceed Cost Structure (9) given the chosen resources/activities/partners.
Lean Canvas — 9 Blocks
Replaces four BMC infrastructure blocks with startup-risk blocks. Built for finding what will kill the business first.
| # | Block | Question | (BMC block it replaces) |
|---|---|---|---|
| 1 | Problem |
Top 1-3 problems + existing alternatives | (Key Partnerships) |
| 2 | Customer Segments |
Target customers + early adopters | (=) |
| 3 | Unique Value Proposition |
Single clear compelling message + high-level concept | (=) |
| 4 | Solution |
Top 1-3 features that address the problems | (Key Activities) |
| 5 | Channels |
Path to customers | (=) |
| 6 | Revenue Streams |
Revenue model, pricing | (=) |
| 7 | Cost Structure |
Customer acquisition, distribution, hosting, people | (=) |
| 8 | Key Metrics |
The few numbers that tell you how the business is doing | (Key Resources) |
| 9 | Unfair Advantage |
What can't be easily copied or bought | (Customer Relationships) |
Fill order: Problem + Customer Segments first (they anchor everything), then UVP,
then the rest. Unfair Advantage is usually filled last and is often empty early — an
honest blank is more useful than a fabricated moat (route moat analysis to compete).
BMC vs Lean Canvas — Which to Use
| Use BMC when… | Use Lean Canvas when… |
|---|---|
| business/model exists; refining or pivoting | brand-new idea, high uncertainty |
| multiple stakeholders / partners / resources matter | speed and risk-spotting matter most |
| infrastructure & partnerships are strategic | problem and unfair advantage are the open questions |
| communicating a model to investors/teams | a founder iterating weekly |
For an early-stage startup blueprint, Lean Canvas pairs with nexus package domain=startup
(venture preset). For a corporate strategy review, BMC pairs with helm scenario/swot.
Stress-Testing & Handoffs
- Coherence test: trace one customer segment through value prop → channel → relationship → revenue, and confirm the left-side blocks (resources/activities/partners/ cost) actually support it. Broken traces are the model's real risk.
- Scenario stress: run the model through
simulation-patterns.md(Baseline/Optimistic/ Pessimistic) — especially Revenue Streams vs Cost Structure sensitivity. - Handoffs: value-proposition zoom-in →
sparkvalue-proposition-canvas.md; moat/unfair-advantage validation →compete(moat-7-powers.md); KPI/Key Metrics instrumentation →pulse; financial modeling of Revenue/Cost →helm forecast(financial-modeling-pitfalls.md).
