Case Study: Blacksmith scales usage-based billing for 6,000+ companies with Lago

Blacksmith scales usage-based billing from 700 to 6,000+ companies with Lago

Blacksmith, a CI/CD infrastructure company, faced the challenge of scaling its complex, usage-based billing for its compute-intensive GitHub Actions service. The company needed a system that could accurately meter highly variable job types and accommodate enterprise agreements without creating a significant engineering overhead. They turned to Lago to provide this billing infrastructure.

Lago provided an API-first, open-source billing platform that seamlessly integrated with Blacksmith's developer-led stack. The solution supported complex metering, aggregation, and enterprise overrides, allowing Blacksmith to experiment with pricing and scale without internal engineering projects. As a result, Blacksmith grew from 700+ paying customers to over 6,000 companies on its platform, all while Lago handled the billing for millions of monthly CI jobs running on hundreds of thousands of compute cores.
