Blacksmith Raises $45 Million at $550 Million Valuation as AI Code Testing Demand Surges

1 articles · Updated · TechCrunch · Aug 12

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.
