Lago is an open-source billing platform founded in 2021, purpose-built to address a persistent infrastructure challenge: helping technology companies construct flexible pricing models and monetize products with precision. The platform delivers event-driven usage metering, hybrid pricing solutions, and comprehensive pricing model management - capabilities essential for firms operating in usage-based and AI-native economies. Backed by over $22 million in funding, Lago has attracted an notable customer roster including PayPal, Mistral AI, CoreWeave, and Synthesia.
The company's technical focus spans billing infrastructure, event-driven usage metering, and AI-native platform design - domains at the intersection of fintech and developer tooling. Its open-source approach has earned recognition from the developer community, with the project accumulating around 10,000 GitHub stars. The founding team includes former Qonto staffers, bringing direct experience from one of Europe's leading fintech operations.
Lago's culture emphasises ownership, reliability, and proactivity. Team members are trusted to drive tasks to completion independently, with an organisational commitment to fast iteration and continuous improvement - principles well suited to building infrastructure that other companies depend on at scale.
