Blacksmith Raises $45M for AI Code Testing
Blacksmith raised $45M at a $550M valuation for AI code testing, targeting the quality-control layer of software development.

AI coding tools can create more software faster, but they also increase the need for testing and validation.
What happened
Blacksmith raised a $45M Series B at a $550M valuation. The company builds an AI code-testing platform for software teams.
Its product sits in the quality-control layer of the developer stack, helping teams test code as software creation accelerates.
Why it matters
The coding market is splitting into multiple layers. Some companies help developers write code. Others help review, test, secure and deploy it.
Blacksmith is positioned in the second group. As AI-generated code becomes normal, teams will need better systems to catch bugs, prevent regressions and maintain reliability.
The bigger picture
The developer-tools opportunity is moving beyond copilots. The bigger market may be the full AI-native software factory: writing, testing, reviewing, deploying and monitoring code with more automation at every step.
