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 November 9, 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.

How they talk about AI
How we classify
We read each company's homepage headline and subheadline against a fixed word list; the most explicit match wins. Not mentioned: no AI language at all. Implied: automated, intelligent, smart or autopilot, without saying AI. AI: AI, machine learning, LLM or generative. AI agents: agents, agentic, autonomous or digital workers.This reads positioning, not product: a company with a strong AI product counts as "not mentioned" if its homepage doesn't say so. Homepages are re-read every month.
