Relace
Relace builds small language models and infrastructure for coding agents, covering code search, retrieval, file merging and a source control system called Relace Repos.
Relace is an AI infrastructure company that builds specialized models and tools for coding agents. Its work concentrates on small language models optimized for code generation tasks, including semantic code search, retrieval, codebase navigation and file merging. The models are co-optimized with the company's own infrastructure; the system applies code edits at 10,000 tokens per second and searches entire codebases in under two seconds.
The product line also includes Relace Repos, a source control system designed for AI agents, offering lightweight push/pull operations, no rate limits and automatic codebase indexing for fast retrieval. Products powered by Relace are used by Lovable, Magic Patterns, Figma and Vercel. The company describes its mission as building "the rails for software on demand" - infrastructure intended to make coding agents faster, more reliable and production-ready.
Relace has raised $23M in a Series A round, backed by Andreessen Horowitz, Matrix Partners and Y Combinator, of which it is an alum. The company is headquartered in San Francisco. Its stated technical domains span small language models, code generation, retrieval, developer tools and source control systems.
