Produces a one-page Lean Canvas with nine blocks (problem, customer, UVP, solution, channels, revenue, cost, metrics, unfair advantage) in markdown or visual HTML/SVG. Use for product thesis framing, strategy stress-testing, option comparison, team alignment.

Generates Lean Canvas with problem, solution, UVP, unfair advantage, channels, segments, revenue, costs, and metrics. Useful for modeling startups, testing business hypotheses, or validating product ideas.
Generates 9-block Business Model Canvas (BMC) or Lean Canvas from business descriptions. Outputs YAML, Mermaid diagrams for startup validation and model innovation.

A lean canvas is a one-page business thesis that makes your assumptions about problem, customer, solution, and viability explicit and testable. Developed by Ash Maurya from Alex Osterwalder's Business Model Canvas, it is specifically adapted for startups and product teams operating under uncertainty. Nine interlocking blocks force you to articulate the whole picture at once so that changing one block's assumptions surfaces the ripple effect on the others.
This skill is a strategic hub, not a specialist tool. It produces the integrated one-page artifact and cross-links to deeper PM skills (/problem-statement, /persona, /jtbd-canvas, /solution-brief, /competitive-analysis, /experiment-design) for single-block depth when needed.
content (default) produces the nine-block canvas as structured markdown.visual produces the markdown canvas AND writes a self-contained, attractive .html file to disk using references/html-template.html as the layout scaffold. The HTML renders the canonical Maurya nine-block layout with polished typography, subtle per-column color accents, confidence badges per block, and print-ready A3 landscape styling. No external assets or CDN dependencies: the file opens correctly in a browser with no network access.If mode is omitted, default to content and state that fallback explicitly.
/experiment-design to prioritize which block assumptions to test first/persona, /problem-statement, /competitive-analysis) instead./prd, /user-stories, /acceptance-criteria; lean canvas is strategy, not specification./problem-statement or /jtbd-canvas and return to lean canvas once the problem is framed.When asked to create a lean canvas, follow these steps:
Resolve mode and intent
Determine whether the request is content or visual. If mode is omitted, default to content and state the fallback.
Clarify the target: new product thesis, existing-business stress test, or side-by-side comparison of options. If unclear, ask once before proceeding.
Collect context and evidence Use user-provided context first: product name, market, target customer, any research already done, existing alternatives users are hiring today, known constraints. If evidence is thin, continue generation but mark gaps in the Evidence & Confidence section and calibrate per-block confidence accordingly. For existing businesses, distinguish current assumptions from validated data explicitly.
Fill the nine blocks in recommended order Fill in this order because each block's answer constrains the next. Do not skip ahead.
a. Problem . Top 3 problems, ranked by pain intensity and frequency. Include Existing Alternatives (what customers do today, including workarounds and non-consumption, not just direct competitors). b. Customer Segments . Who has these problems most acutely? Name Early Adopters as a distinct subset you will reach first. Early Adopters are more painful, more reachable, and more willing to try a new solution than the broader segment. c. Unique Value Proposition (UVP) . One sentence that makes a clear, testable promise. Include a High-Level Concept ("X for Y" analogy) that accelerates understanding for busy readers. d. Solution . Top 3 features that address the top 3 problems. Map 1:1 to the Problem block. Keep it concrete but do not over-engineer; this is a hypothesis, not a spec. e. Channels . Free and paid paths to your early adopters. Distinguish compounding channels (content, SEO, community) from traction-demonstrating channels (outbound, paid ads). f. Revenue Streams . Model (subscription, transaction, freemium, services), price point, expected volume, and LTV. Show the math so the revenue thesis is inspectable. g. Cost Structure . CAC, fixed vs variable, and the cost driver that shapes the growth curve. h. Key Metrics . The 3 to 5 leading indicators that signal whether the model is working. AARRR (Acquisition, Activation, Retention, Revenue, Referral) is a useful default frame. i. Unfair Advantage . What cannot be easily copied or bought. Empty is acceptable if framed as an open question; never fabricate a moat.
Apply evidence and confidence policy
Tag each block with High, Medium, or Low confidence plus a one-line rationale.
Populate the Evidence & Confidence section: Validated (assumptions with named sources), Assumed (no data yet), Open Questions (what you would need to learn to raise confidence), Governance (who owns the canvas and when it is revisited).
A block marked "High" must name a specific evidence source, not a generic claim.
Render and write the visual file (visual mode only)
Read references/html-template.html. It is a complete, self-contained HTML5 document using CSS Grid to express the canonical Maurya nine-block layout, with per-column color accents, confidence badges, and A3 landscape print styling.
Fill every {{PLACEHOLDER}} token in the template with content from the markdown canvas:
{{PRODUCT_NAME}}, {{CREATED_DATE}}, {{PURPOSE}}, {{OVERALL_CONFIDENCE}} from the canvas header.{{PROBLEM_CONTENT}}, {{EXISTING_ALTERNATIVES}}, {{SOLUTION_CONTENT}}, {{UVP_CONTENT}}, {{HIGH_LEVEL_CONCEPT}}, {{ADVANTAGE_CONTENT}}, {{CUSTOMER_CONTENT}}, {{EARLY_ADOPTERS}}, {{METRICS_CONTENT}}, {{CHANNELS_CONTENT}}, {{COST_CONTENT}}, {{REVENUE_CONTENT}} from the respective blocks. Use a <ul><li> list for multi-item blocks; keep cell content concise (one-line summaries, not the full markdown detail) so the visual stays scannable.{{CONF_PROBLEM}}, {{CONF_SOLUTION}}, {{CONF_UVP}}, {{CONF_ADVANTAGE}}, {{CONF_CUSTOMER}}, {{CONF_METRICS}}, {{CONF_CHANNELS}}, {{CONF_COST}}, {{CONF_REVENUE}} with the single letter H, M, or L matching each block's confidence tag. Each appears twice in the template (once in the class attribute for styling, once as visible text).{{VALIDATED_COUNT}}, {{ASSUMED_COUNT}}, {{OPEN_QUESTIONS_COUNT}}, {{OWNER}}, {{NEXT_REVIEW}} in the footer evidence strip.
Write the filled document to disk at a user-specified path, or default to ./lean-canvas-{slug}.html in the current working directory (where {slug} is the product name lowercased with non-alphanumeric characters replaced by hyphens).
Do not introduce external font or CSS links; the template is intentionally self-contained.
In content mode, skip this step entirely.Finalize for direct use
Remove all template guidance blockquotes (> notes) from the final artifact.
Verify UVP is decision-changing and testable, not marketing fluff.
Confirm Early Adopters is a distinct subset (not a restatement of Customer Segments).
Confirm Solution block items map 1:1 to Problem block items.
