While generative tools accelerate output, they often leave teams struggling with verification bottlenecks. Blacksmith offers a platform that handles continuous integration workloads and utilizes its 'Codesmith' agent to automatically resolve failed code checks.

Blacksmith Valuation Hits $550 Million Amid AI Coding Boom
A 10-fold valuation jump in less than a year has propelled AI testing startup Blacksmith to a $550 million price tag. The company, which helps developers verify code generated by AI tools, secured $45 million in a Series B round led by Peak XV Partners, signaling investor confidence in automated quality assurance.
CEO Aditya Jayaprakash notes that the startup has expanded its client base from 700 to over 5,000 customers, counting Mercury, Supabase, and Expensify among its users. The company has scaled its internal team to 30 employees while growing its annualized revenue into the tens of millions. Despite entering a crowded market dominated by giants like GitHub Actions and cloud-native services from Microsoft, Google, and Amazon, Jayaprakash insists that Blacksmith’s competitive edge remains in superior testing speed and cost-efficiency. The firm now plans to evolve into a full-stack toolset, aiming to assist developers through the entire lifecycle of writing, validating, and merging software.
