About
Buildt was a Y Combinator W23-backed AI developer tool that enabled engineers to perform semantic, natural-language search across large codebases. The tool allowed developers to find relevant code by asking contextual questions rather than using keyword search, helping teams at companies like Stripe quickly understand unfamiliar or large repositories. Buildt has since rebranded and evolved into Cosine, an AI coding model company that now develops the Lumen family of coding-specialized language models and offers a coding agent platform (CLI and Cloud) targeting enterprise and sovereign AI deployments.
