The Series B led by Peak XV Partners brings the startup’s valuation to $550 million, up from $60 million less than a year ago.
Blacksmith raised a $45 million Series B led by Peak XV Partners, valuing the startup at $550 million. The new valuation is nearly 10 times the $60 million figure from its Series A less than a year ago. Existing investors GV and Y Combinator joined the round, bringing total funding to $58.5 million.
Founded in 2024, Blacksmith started as a cloud provider for continuous integration workloads and now helps companies build, test, and verify software before production. The startup serves more than 5,000 customers, including Mercury, Supabase, Clerk, Ashby, and Expensify, up from 700 a year ago. Blacksmith also launched Codesmith, an AI coding agent that automatically fixes failed code checks.
The rise of AI coding tools from Cursor, OpenAI, and Anthropic makes code generation easier, but validation remains a bottleneck. Blacksmith competes on testing speed and affordability against GitHub Actions, Cursor Automations, and cloud rivals. For builders, faster validation means fewer delays and more confident merges.
Blacksmith plans to expand into a broader suite of coding tools to help developers write, validate, and merge software faster. The company reached $10 million in annualized revenue with 10 employees and now reports tens of millions in revenue with about 30 staff. Watch whether its next moves can hold off GitHub Actions and cloud rivals.
