Start with revenue
Payment providers supply observed orders, refunds, fees, and customer identities. Revenue is not inferred from traffic.
AI unit economics
Traffic alone cannot tell you whether an AI product is healthy. Grow or Die joins observed product activity, payment revenue, and provider-reported model usage so the denominator and the cost come from real sources.
Why this is different
Payment providers supply observed orders, refunds, fees, and customer identities. Revenue is not inferred from traffic.
The SDK reports token usage, cache usage, status, and timing. Versioned server prices turn those facts into cost.
Analytics supplies visitors and acquisition context. Missing coverage stays visible instead of silently becoming zero.
Site-wide profit works first. Customer-level profit appears only after your backend links the same account to payment and usage.
Cost coverage and reconciliation
Grow or Die separates priced, attributable model usage from unallocated cost. Missing identity or pricing evidence stays visible instead of quietly becoming zero.
Provider-reported usage is priced on the server and joined to a customer only when the same canonical account is present in the payment and model-call evidence.
Usage without a trustworthy account link remains in an explicit unallocated bucket. It still counts toward site-wide cost, but it is not assigned to a customer by guesswork.
Contribution profit is complete only when the selected window has compatible revenue, visitor, identity, and model-price coverage. Partial coverage produces a partial result, not a confident margin claim.
Compare priced SDK events with the provider bill for the same provider, project, currency, and time window. The difference is reported as a reconciliation gap and investigated before an automated cost decision is made.
The honest formula
Unallocated cost and reconciliation gaps stay next to that result. They are not subtracted twice, assigned to convenient customers, or hidden behind a zero. See AI cost attribution for the event-level method.
The next useful question
Once the top-line formula is trustworthy, cost attribution shows where model spend originates and customer profitability shows whether the account paying the revenue also consumes the cost.
