Creator: First to Market

Developer-first infrastructure that ingests raw product-usage events in real time, applies pricing/rating logic, and outputs invoices, credits, entitlements and recognized revenue for software and AI companies.

Last updated September 27, 2026

Our read

Usage-based billing grew out of the challenge of charging for AI-native products. Metronome's 2022 launch marks the start, and a second entrant followed within the year. Consolidation started quickly, too. Stripe bought Octane about 23 months in, and Stripe, Salesforce, Adyen and Kong have all acquired metering companies since. We count about 15 independent pure-plays left and no unicorns in the developer-first cohort. The name is contested, and Orb started pushing 'revenue design' as the successor term this year. We've audited ten companies here.
