This page is designed to help you find out whether PerUnit is good and if it is the right choice for you.
Your AI bill is growing — but which customers, features, and pricing tiers are driving it? OpenAI, Anthropic, and Google dashboards show totals. Totals don't help you decide who to charge more, what to gate, or where to cut.
PerUnit breaks down AI spend by customer, feature, and pricing tier so founders, PMs, and CFOs can make confident product and pricing decisions. See cost per customer, per feature, and per tier — and connect it to revenue via Stripe.
Connect directly to your AI provider APIs. No data warehouse, no pipelines, no data engineering. Tag requests with customer IDs via our SDK or metadata fields in your API calls, and we attribute every dollar of AI spend to the customers and features driving it.
Use PerUnit to spot expensive free users, gate costly features behind paid plans, and justify pricing changes with real unit economics. Get live dashboards that compare AI costs to revenue by account and tier. Onboard in under a week.
Early access is $99/month. No long-term commitment — billing starts only after integration is live. We're building with founders who care about AI margins. perunit.ai

PerUnit is built for AI unit economics, not just cost tracking. We break down AI spend by:
Customer — see which accounts drive costs Feature — see which AI features burn through tokens Pricing tier — free vs paid user breakdown We connect AI costs to revenue via Stripe. Provider dashboards show totals; observability tools show tokens. PerUnit shows who's driving costs and whether they're profitable. No data warehouse or pipelines — direct API sync to OpenAI, Anthropic, and Google.
PerUnit is built for product and pricing decisions, not observability. Competitors focus on tokens, latency, and traces. We focus on:
Cost per customer Cost per feature Cost per tier — connected to revenue If you need to know who to charge more, what to gate, or where to cut, PerUnit gives you that. No pipelines, no data engineering, no data warehouse.
Founders, product managers, and CFOs at companies building AI-powered products. Anyone who needs to answer:
Which customers cost the most? Are free users profitable? Should we gate AI behind paid plans? Teams that care about unit economics and margins, not just total spend.
We've shipped products with AI and watched margins disappear without knowing why. The AI bill was one number — we couldn't see which customers or features were driving it. Every product and pricing decision was a guess.
We built PerUnit so product teams can have the same clarity on AI costs that they have on revenue and headcount.

PerUnit is in early access. We're onboarding a small group of teams who need clarity on their AI unit economics. Our early users are founders and PMs at companies building AI features — from early-stage to growth — who want cost attribution before scaling further.
