Blacksmith raises $66M for software testing infrastructure
Sequoia leads a $66 million Series C as Blacksmith expands infrastructure for building and testing software.
What happened
Blacksmith raised a $66 million Series C led by Sequoia Capital at a $1 billion valuation. The round brings its disclosed funding to $125 million. The company provides computing infrastructure for continuous integration, the automated process that builds and tests code changes before they are merged.
Why it matters
AI coding tools can increase the volume of changes developers produce. Each change still needs validation, which puts pressure on test systems and computing capacity. Blacksmith is targeting that downstream workload, with the financing intended to expand its team and infrastructure.
The bigger picture
Code generation and software delivery are connected markets. Producing more code is valuable only if teams can check and maintain it efficiently. That creates opportunities for companies improving testing, review and operational reliability. Blacksmith's challenge is to keep those workflows responsive as customer demand fluctuates and the volume of AI-generated changes continues to evolve.
