About OpenMeter
Based in California, US, and co-founded by Peter Marton, Andras Toth, Mark Sagi-Kazar, and Andras Hajgato in 2023, Tailfin Cloud Inc. trading under the name OpenMeter operates as an open-source metering company for AI (artificial intelligence), API (application programming interface), and DevOps applications. In September 2025, Kong Inc. acquired OpenMeter. Financial terms of the transaction were not disclosed. The company offers usage monetization solutions on precise usage metering in AI and cloud environments, for engineers, by providing scalable real-time metering to transform data into revenue. OpenMeter's product suite includes the Usage Lake, which caters to the data requirements of engineering, product, revenue, and efficiency teams. It enables users to bill from any events, metrics, and logs, attributing shared costs to customers and products based on meters. Additionally, built for developers, OpenMeter provides SDKs for popular programming languages like TypeScript, Python, and Go, empowering users to meter millions of events per second and access real-time aggregated usage data. The firm generates revenue by offering its platform under different subscription plans such as OpenMeter Open Source at free of cost, OpenMeter Cloud Professional at USD 249 per month, etc. The September 2025 acquisition aims to integrate OpenMeter with Kong's platform and strengthen OpenMeter's existing platform and unlock AI and API monetization for the agentic era.
