Blacksmith, a San Francisco-based company, has secured $45 million in Series B funding, bringing its total funding to $58.5 million. The round, led by Peak XV Partners, follows participation from Y Combinator and GV. The additional capital will primarily be used for expanding computing infrastructure and hiring engineers in New York and San Francisco.
The company provides cloud infrastructure for validating software code, helping engineering teams build, test, and verify changes before deployment. Customers include Supabase, Clerk, Ashby, and Mercury. Blacksmith's platform becomes increasingly important as AI coding tools, like Claude Code and Codex, generate code faster but also lead to more pull requests.
Blacksmith's co-founder and CEO, Aditya Jayaprakash, notes that validation has become a bottleneck due to the surge in pull requests. The company's cloud runs GitHub Actions on dedicated infrastructure, optimized for software testing. Migration only requires one line change within a workflow file, enabling teams to move workloads without rebuilding their development processes.
Since January, Blacksmith's cloud CI workloads have increased between 5% to 10% weekly, with over 6,000 companies now using the platform. The company's Codesmith product further expands its AI platform, allowing developers to delegate coding tasks to an AI system that builds, fixes, and validates code. Blacksmith aims to streamline the software development lifecycle by reducing friction between code generation and deployment.
