Summary
$45 million in Series B funding valued Blacksmith at $550 million, a sharp jump from its $60 million valuation less than a year after a $10 million Series A.
More than 5,000 customers now use Blacksmith's software build, test and verification tools, up from over 700, as AI coding tools speed code generation but leave validation as a growing bottleneck.
Blacksmith said total funding has reached $58.5 million and revenue has climbed from a $10 million annualized run rate with 10 employees to tens of millions of dollars, with some customers spending more than $1 million a year.
Founded in 2024, the startup has expanded from cloud-based continuous integration into Codesmith, an AI agent that fixes failed code checks, while competing against GitHub, major cloud providers and built-in tools from Codex and Claude Code.
Blacksmith plans to broaden into a fuller coding suite aimed at helping developers write, validate and merge software faster as AI-generated code reshapes software workflows.
