Conductor (conductor.build) is a macOS desktop application that lets developers run multiple AI coding agents — specifically Anthropic's Claude Code and OpenAI's Codex — in parallel on their local machine. Each agent operates in an isolated Git worktree, allowing simultaneous work on multiple features or fixes without conflicts. The company's mission is to build 'the human interface to AI organizations,' providing orchestration and review tools for developers as AI teams replace sequential, human-led coding workflows. Conductor was founded in 2024, is part of YC S24, and raised a $22M Series A in March 2026.
