Relace builds specialized AI infrastructure for coding agents and code generation workflows. The company develops small, fast language models trained specifically for code-related tasks - including retrieval, file merging, and codebase navigation - alongside tools designed to make these agents faster and more reliable in production. Relace models achieve 10,000 tokens per second when applying code edits and can search entire codebases in under two seconds.
The company's main product, Relace Repos, is a source control system designed for AI agents rather than traditional developer workflows. It features lightweight push/pull operations, no rate limits, and automatic codebase indexing to enable rapid retrieval across large repositories. The infrastructure is built on co-optimized models and systems to maximize performance for autonomous coding tasks.
Relace raised $23m in Series A funding in late 2025, led by Andreessen Horowitz with participation from Matrix Partners and Y Combinator. The company is based in San Francisco and counts companies including Lovable, Magic Patterns, Figma, and Vercel among its customers and partners.
