Brief

Conductor is a Mac app that runs multiple coding agents (e.g., Claude, Codex) on an isolated codebase with one click; the company raised a $22M Series A and on 2026-05-08 launched Conductor Cloud so agents continue working after you close your laptop. Founders Charlie Holtz and Jackson DeCampos told YC's Aaron Epstein they arrived at Conductor after cycling through a dozen ideas while building dev tools for themselves.

Why it matters

Conductor is a Mac app that runs multiple coding agents concurrently, creating an isolated copy of your codebase in one click and letting models like Claude or Codex work on tasks.

Key details

  • Conductor raised a $22 million Series A and launched Conductor Cloud (announced 2026-05-08) to let agents keep working after you close your laptop.
  • Co-founders Charlie Holtz and Jackson DeCampos told YC's Aaron Epstein on Founder Firesides they cycled through a dozen ideas and built Conductor after creating dev tools for their own use and watching top engineers use coding agents.

Fun chatting with @aaron_epstein. He's the one who first gave us the idea to build dev tools!

Conductor (@conductor_build) is a Mac app that lets you run multiple coding agents at the same time. Create an isolated copy of your codebase in one click, tell Claude or Codex to go work, and review and merge the results.

The company just raised a $22 million Series A, and today is launching Conductor Cloud, which lets agents keep working even after you close your laptop.

In this episode of Founder Firesides, co-founders @charlieholtz and @jacksondecampos sat down with YC's @aaron_epstein to talk about cycling through a dozen ideas before landing on the one that stuck, how building dev tools for themselves led to Conductor, and what they've learned from watching the best engineers in the world work with coding agents every day.
