Blacksmith Valuation Reaches Milestone
Code-testing startup Blacksmith has achieved a $1 billion valuation following a $66 million Series C funding round led by Sequoia Capital, according to reports. The latest financial milestone comes approximately two months after the company secured a $45 million Series B round at a $550 million valuation.
The recent funding brings Blacksmith's total capital raised to approximately $124.5 million. The startup's valuation has experienced a rapid ascent, moving from roughly $60 million following its Series A round to its current unicorn status as AI-generated code increasingly floods developer pipelines.
Growth and Enterprise Adoption
Underlying business metrics reflect significant expansion for the firm. Research findings indicate that revenue has climbed from early single-digit millions into the tens of millions, with certain enterprise customers spending upwards of $1 million annually.
The company's customer base expanded from approximately 700 to 800 clients in late 2025 to a range between 5,000 and 6,000 customers. Notable named users of Blacksmith's platform include Supabase and Expensify, while company headcount grew from about 10 employees to approximately 30.
Technology and Market Positioning
Founded in San Francisco in 2024 by CEO Aditya Jayaprakash, Aayush Shah, and Aditya Maru, Blacksmith provides high-performance cloud runners and caching tools designed for continuous integration workloads. The founders participated in Y Combinator’s Winter 2024 batch.
The startup positions itself as a faster and more cost-effective alternative to GitHub Actions. Additionally, Blacksmith has expanded into AI-assisted tooling with its Codesmith coding agent, which automatically diagnoses and attempts to fix failed code checks.
