$23 million Series A funding led by Andreessen Horowitz signals a fundamental infrastructure shift in AI coding agents. Relace is building specialized models that reduce codebase context retrieval from minutes to 1-2 seconds and merge file edits at over 10,000 tokens per second.

The bottleneck has evolved. Large language models proved they can generate code at scale, but deploying that code in production environments remains a complex infrastructure challenge. As coding agents move from experimental tools to enterprise workflows powering “software on demand,” the need for purpose-built infrastructure becomes critical.
