Getting AI Coding Agents to solve hard problems in complex codebases

Hiring Pitch

CodeLayer is the best way to get AI to solve hard problems in complex codebases. We help CTOs and VPEs drive the transition to 99% AI-written code in their engineering orgs.

We grew 100% in the last month, we welcomed two YC customers with 50-100 person engineering teams, and we're in paid pilots with several publicly-traded teams with thousands of engineers.

Learn more about our mission, why Stanford says AI coding agents can't solve hard problems in complex codebases, and how we're changing that in our Getting AI to Work in Complex Codebases (with over 400 comments on HN) and our talk at YC from august: Advanced Context Engineering for Coding Agents
