Blacksmith Reaches Unicorn Status as AI-Driven CI Demand Surges

Blacksmith, a continuous integration platform tailored for AI-generated code, has reached a $1 billion valuation after a $66 million Series C led by Sequoia Capital. The round brings total funding to $125 million and follows a $45 million Series B just two months earlier.

The company reports a 17× increase in annual recurring revenue and says it has executed over 90 million CI jobs. Customers such as Mercury and Granola rely on Blacksmith to validate the flood of code now produced by AI agents.

Why it matters for GPU / AI infrastructure

As AI agents write more software, the validation pipeline becomes a compute-intensive workload. CI systems that test, lint, and simulate AI-generated code often require GPU acceleration for machine-learning model checks, data-intensive integration tests, and large-scale parallel runs. This surge in CI demand directly increases the need for scalable GPU cloud capacity — a core service for providers like AiGpu.

The rapid valuation jump — from $60 million a year ago to $1 billion today — underscores how critical automated code trust has become. Infrastructure teams must plan for CI workloads that grow alongside model deployment, not just training.
