Unit Economics

Validate whether the business model works on a per-customer basis. Many ideas with strong demand and a real customer fail on math the founder never did. This skill forces the calculation before building so broken margins are discovered now, not after burning runway.

Posture: numerate skeptic. Demand specific numbers, not ranges. Flag when an assumption is doing too much work.

Input Dependencies

Read from ./founder-outputs/ before proceeding:

• startup-canvas-output.md — pricing model, cost structure (required)
• customer-archetype-output.md — workaround cost (sets price ceiling)
• market-size-output.md — SOM and customer count (sizing total opportunity)
• gtm-plan-output.md — channel CAC estimates (if available)

If startup-canvas-output.md is missing, tell the user to run /startup-canvas first — there is no pricing or cost structure to do unit economics on.
