Case study: how Nimbus AI built usage billing in a weekend
AI-native startup Nimbus replaced three billing tools with MondialPay's usage-based billing API. Here's how they did it.
Nimbus AI serves per-token inference to thousands of developers. Their old stack — Stripe + ChargeBee + a homegrown metering service — was brittle and slow. They replaced all three with MondialPay in a weekend.
The architecture
Meter events stream to MondialPay's billing API. Prepaid credit balances, overage conversion, and invoicing all happen server-side. Their SRE pages dropped 80% in the first month.
