From $60 Million to $550 Million
Startup Blacksmith has raised a $45 million Series B led by Peak XV Partners, valuing the company at $550 million. That's nearly a 9x jump from the $60 million valuation it held less than a year ago, when it raised a $10 million Series A. Existing investors GV and Y Combinator also participated in this round, bringing the company's total funding to date to $58.5 million.
The growth is also visible in customer numbers. Founded in 2024, Blacksmith says it now has more than 5,000 customers, including Mercury, Supabase, Clerk, Ashby, and Expensify. That's more than 7 times the roughly 700 customers it had a year ago. Headcount has grown from 10 to 30, and annual revenue, which started at around $10 million in annual recurring revenue (ARR), is now in the "tens of millions of dollars," the company said. While it did not disclose exact figures, it noted that some large customers pay more than $1 million per year.
Code Got Faster, But Verification Didn't Keep Up
Blacksmith's focus is on "verification." As AI coding tools like Cursor, OpenAI's Codex, and Anthropic's Claude Code have spread, the volume of code a single developer can produce has grown significantly. The problem is that verifying whether that code actually works correctly hasn't sped up at the same pace. CEO Jayaprakash said, "Verifying code is still the bottleneck, and as people write more code, that bottleneck is only getting bigger."
Blacksmith originally started as a cloud service handling continuous integration (CI) — automatically building and testing code before it's merged. It later expanded its platform by adding "Codesmith," an AI agent that automatically fixes failed code checks. However, the market is already crowded. Competitors include GitHub Actions, Cursor's automation features, the built-in verification capabilities of Codex and Claude Code, and AI code verification services offered by Amazon Web Services (AWS), Microsoft Azure, and Google Cloud. The company says it is competing on verification speed and pricing.

So What Does This Mean
Blacksmith's rapid growth points to new demand created by AI coding. While code generation itself has already become commoditized, confirming that the resulting code is safe and behaves as intended is becoming a heavier burden for both people and tools. Investors backing this space with a 9x valuation jump suggests verification is being seen as the next place where money will be made in the AI coding ecosystem. But with major players like GitHub, OpenAI, and Anthropic continuing to build verification features into their own tools, how long an independent startup like Blacksmith can hold its ground will depend on the competition ahead.
