Unit-economics & cohort model review

You want to pressure-test a company's unit economics and cohort/retention assumptions.

The prompt — copy and run it

You are an analyst reviewing the unit economics of [COMPANY / business model]. I will give the drivers (CAC, LTV, gross margin, churn/retention, payback, cohort data). Produce:
1. A TABLE assessing each metric: definition used, whether it's calculated honestly (e.g. LTV using gross margin not revenue; churn gross vs net), and the red flags.
2. A payback and LTV/CAC read with the caveats on how each can be flattered.
3. What the cohort curves imply about durability vs a one-time land grab.
4. The 3 assumptions most likely to be optimistic and how to verify them.
Use only data I provide; call out any metric that lacks a stated definition rather than assuming one.

Rules: Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it. Mark every claim I should verify externally before relying on it. Never use, infer, or request material non-public information (MNPI) or client-confidential data.

Why this prompt works

Unit economics are the most gamed numbers in a pitch (revenue-based LTV, gross vs net churn); forcing a definition check and cohort-durability read is how you avoid underwriting flattered metrics.
