Start with revenue
Payment providers supply observed orders, refunds, fees, and customer identities. Revenue is not inferred from traffic.
AI unit economics
Know what each visitor earns, what AI costs, and what is left.
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.
Revenue
What customers paid
AI cost
Priced model usage
Profit
What the product keeps
Why this is different
Token totals are a cost input, not a business answer.
Price model usage on the server
The SDK reports token usage, cache usage, status, and timing. Versioned server prices turn those facts into cost.
Use honest denominators
Analytics supplies visitors and acquisition context. Missing coverage stays visible instead of silently becoming zero.
Move from site to customer
Site-wide profit works first. Customer-level profit appears only after your backend links the same account to payment and usage.
The next useful question
Which feature, model, or customer changed the margin?
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.
