The funding brings the company to a valuation of $550 million.\n\nThe foundation of Blacksmith is continuous integration, which combines code development with cloud-based testing instead of on the developer’s computer.\n\nThis means that the entire developer team can continue working on code at the same time, submit their changes collaboratively, and then Blacksmith tests submissions as they come in, commits new changes to the codebase if they pass, rejects them when they fail and sends back notes on what went wrong when issues are found.\n\n“Writing code has gotten dramatically easier. Validating it hasn’t,” said co-founder and Chief Executive Aditya “JP” Jayaprakash. “Every piece of code an agent writes still has to be built, tested and reviewed before it can ship. That validation layer is going to become increasingly important as more software is written by agents.”\n\nThe company recently launched a service called [codesmith](https://docs.blacksmith.sh/codesmith/build-from-anywhere), a cloud coding agent that developers can delegate tasks to. It moves beyond building features and fixing bugs by working inside the validation loop and diagnosing integration failures, automatically fixing them and healing submissions to the codebase.\n\nThe company said that the funding will go into compute infrastructure. Blacksmith currently manages hundreds of thousands of cores and plans to grow that by an order of magnitude in the coming months to handle expected demand.\n\nBlacksmith also said jobs running on its service have grown between 5% and 10% week over week since the beginning of the year. More than 6,000 companies now use the service, including Supabase Inc., Clerk Inc., Ashby Inc. and Mercury Systems Inc., up from approximately 800 when the company announced its [Series A](https://siliconangle.com/2025/09/17/dev-tool-startup-blacksmith-software-gets-10m-accelerate-continuous-integration/) last September.\n\n##### Image: SiliconANGLE / Dreamina AI\n\n# A message from John Furrier, co-founder of SiliconANGLE:\n\nSupport our mission to keep content open and free by engaging with theCUBE community. **Join theCUBE’s Alumni Trust Network**, where technology leaders connect, share intelligence and create opportunities.\n\n**15M+ viewers of theCUBE videos**, powering conversations across AI, cloud, cybersecurity and more** 11.4k+ theCUBE alumni**— Connect with more than 11,400 tech and business leaders shaping the future through a unique trusted-based network.\n\n# Are you AWS customer?
