Background & analysis
On October 21, 2026, AI code-testing infrastructure startup Blacksmith announced a $66 million Series C funding round led by Sequoia Capital, valuing the company at $1 billion. This milestone comes just two months after the startup raised a $45 million Series B round led by Peak XV Partners at a valuation of $550 million, nearly doubling its valuation in a short period. The rapid growth is driven by the surge of AI-generated code, which has flooded companies with more code than traditional testing systems can handle. With this new round, Blacksmith's total funding has reached approximately $124.5 million. The company reports that its platform is now used by over 10,000 companies, up from about 5,000 in August, with prominent startups such as Granola, Handshake, Supabase, and LangChain among its customers.
