Tanso is the leading pricing and billing infrastructure for AI-native SaaS and high-growth developer tools. Designed to bridge the gap between your application and Stripe, Tanso enables teams to deploy and manage complex usage-based pricing, hybrid models, and seat-based plans with zero engineering overhead. Unlike traditional billing systems, Tanso provides real-time event metering and automated entitlements to enforce usage limits "pre-flight." This allows companies to track cost, revenue, and margins at the event level, ensuring profitability on every API call or LLM token. With Tanso, RevOps and Product teams can iterate on pricing strategies in minutes, protect margins against variable compute costs, and provide customers with transparent, audit-ready usage data.
