Proxy + ledger in one system
Competitors: Gateway → Events → Billing → Accounting. Finno: Reserve → Upstream → Finalize — no gap, no reconciliation, no lost events.
Finno sits at the intersection of API gateways, usage billing, financial ledger infrastructure, and API monetization — and defines revenue infrastructure.
Finno is an API Revenue OS — not an API gateway. It deploys alongside Kong, WSO2, Apigee, and every ESB you already run, and defines a new category: revenue infrastructure for API businesses.

Competitors: Gateway → Events → Billing → Accounting. Finno: Reserve → Upstream → Finalize — no gap, no reconciliation, no lost events.
Most competitors track balances. Finno maintains six accounts — Float, Receivable, Wallet, Owed, Deferred Revenue, Revenue — audit-ready from day one.
Funds are reserved and credit verified before upstream runs. The financial exposure of post-billing systems disappears.
On-premise, air-gapped, and national operators — where SaaS competitors cannot go.
23 background checks on ledger, payments, rollups, and gateway telemetry — from accounting integrity to settlement failures and overdue invoices. Every finding ships with evidence and a recommended action, with zero hot-path overhead.
Machine credentials for ERP, maker/checker corrective adjustments, and claim-file billing disputes — on the same books, not a side spreadsheet.
The biggest competitor is engineering teams building Kafka + Stripe + custom billing + a reconciliation team — while keeping Kong or WSO2 for traffic. Finno replaces the monetization stack, not your gateway.
Stop building monetization infrastructure. Deploy Finno next to your gateway.
Kong + Kafka + Stripe + custom billing + a reconciliation team — or one product on your infrastructure.
