Business Model

Business Model

Captures an entire business or product bet on one page using Ash Maurya's Lean Canvas (the startup-oriented variant of Osterwalder's Business Model Canvas), then ranks blocks by risk so you validate the assumption most likely to kill the business — before you spend a quarter building.

Grounded in: Running Lean — Ash Maurya: the Lean Canvas and finding the riskiest block to validate first. Go deeper (The Product Channel): Product Led Growth

When to use this

• A new product, feature line, or 0-to-1 bet needs a one-page model before it goes to leadership or a build team.
• You have a deck full of vision but can't crisply say who pays, for what, and why you instead of an incumbent.
• An existing product's economics feel off and you need to see the whole revenue/cost/segment picture at once.
• You're prepping a stage-gate, investment ask, or kill/continue decision and need the riskiest assumption named explicitly.
• A founder or stakeholder keeps debating the solution before anyone agreed on the problem or the customer.

Before you start (gather these)

• Customer segment(s) — who specifically has the problem, and who's the early adopter (not "everyone").
• Top 1–3 problems — the actual pains, and what they do today as a workaround.
• How money moves — pricing idea, who pays, and rough cost structure (even ballpark).
• Why you — any unfair advantage, traction, or asset a competitor can't copy.

If two or more of these are missing or vague, ASK 2–4 sharp clarifying questions before filling the canvas — e.g. "Who's the single early-adopter segment, not the eventual market?", "What does this person do today instead?", "Who actually pays, and roughly how much?", "What can't a well-funded competitor copy in 6 months?" If the inputs are already provided, proceed and state any assumptions inline as [ASSUMPTION: ...] so they're visible and testable.

Existing-business mode. If this is a running business (has ARR, paying users, or live traffic) rather than a 0-to-1 bet, the problem and segment are already validated by the fact that people pay — don't re-litigate them as interview assumptions. Instead:

• Pull segment, problem, and unit-economics from data, not interviews. Read who actually pays and churns from billing/analytics, which problem retains them from usage and support tickets, and CAC/LTV/margin from real revenue and cost numbers. Treat these blocks as measured, not assumed (Uncertainty drops accordingly).
• Default the risk lens to Solution + Key Metrics — the assumptions most likely to still be unproven once problem/segment are settled (does the solution actually move the metric that compounds the model?).
• Look for the unfair advantage in what you already own — proprietary data, an installed user base, or distribution a new entrant can't buy is usually the real moat for an operating business.

Process

1. Lock the segment first. Fill the customer segment and name an early adopter sub-segment. Everything else inherits from who. If the segment is "everyone," it's wrong — narrow it.
2. Problem before solution. Write the top 1–3 problems and the existing alternatives (what they hack together today). Resist writing solutions here.
3. Draft the UVP as a single, specific sentence. "We help [segment] achieve [outcome] without [pain of the old way]." Add a high-level concept ("X for Y") if it sharpens it. Make it a claim, not a feature list.
4. Map solution to problems 1:1. Each top problem gets exactly one solution bullet. If a solution doesn't trace to a problem, cut it.
5. Channels — path to customers. List how you reach the segment (inbound, outbound, partnerships, communities). Flag which are unproven.
6. Revenue & cost on the same pass. Revenue streams + pricing model; cost structure (CAC, COGS, fixed). Do a back-of-envelope unit-economics sanity check — does a customer net positive?
7. Key metrics — the one number. Pick the 1–3 numbers that tell you the model works (activation, retention, paid conversion). Name the single "North Star."
8. Unfair advantage — be honest. Only list things that can't be easily copied or bought (insider info, network effects, community, exclusive partnerships). "Great team" and "first mover" don't count.
9. Rank risk and pick ONE. Score all nine blocks on the two axes that matter: Uncertainty (1–5, how unproven the assumption is) and Fatal (1–5, how badly the business dies if it's wrong). Risk = Uncertainty × Fatal (range 1–25). Break ties by the higher Fatal score. The highest-Risk block is what you validate next — name it and propose the cheapest experiment to test it.

## Riskiest Block to Validate First

Risk = Uncertainty × Fatal (1–25). Score **all nine blocks**; break ties by the higher Fatal score.

| Block | Uncertainty (1–5) | Fatal if wrong? (1–5) | Risk (U × F) |
|---|---|---|---|
| Problem | [n] | [n] | [n] |
| Customer Segments | [n] | [n] | [n] |
| UVP | [n] | [n] | [n] |
| Solution | [n] | [n] | [n] |
| Channels | [n] | [n] | [n] |

| Unfair Advantage | [n] | [n] | [n] |

**Riskiest block: [name]** — [one sentence: why this assumption, if false, sinks the model].

**Cheapest test:** [the smallest experiment — e.g. 5 problem interviews, a fake-door landing page, a pre-sale of 10 units, a smoke-test ad] · **Pass/fail signal:** [the specific result that confirms or kills it] · **Timebox:** [days/weeks].

Avoid (anti-patterns)

• Solutions hiding in the Problem block. "They need a dashboard" is a solution; the problem is "they can't see X without manual spreadsheet work." Keep them separate.
• "Everyone" as a segment. A canvas with a broad market and no named early adopter can't be validated; it just feels safe.
• A UVP that's a feature list. "Fast, secure, AI-powered" is not a value proposition. It must name the outcome and the pain it removes.
• Fake unfair advantage. Listing "passion," "first mover," or "great team" — all copyable or buyable. If a competitor with money could replicate it this quarter, it's not unfair.
• Skipping the risk ranking. A filled canvas with no riskiest-block call is a poster, not a decision tool. The whole point is choosing what to test first.

Tips

• Fill the canvas in problem-driven order (segment → problem → UVP → solution), not left-to-right. The right side (revenue, cost) only makes sense once the left side is real.
• Pressure-test revenue against cost on the same pass — a beautiful UVP with LTV < CAC is a charity, not a business.
• For the riskiest block, default to the cheapest test that can return a no. You're hunting for disconfirmation, not validation theater.
• Re-run this monthly on live bets. The riskiest block changes as you de-risk; last month's scariest assumption is often this month's known fact.
