Meta acquires Conductor, a multi-agent AI coding tool

Conductor's appeal was never a single model but the orchestration around it: a developer could run several coding agents at once, each in an isolated copy of the codebase, then review and merge the output. That workflow drew engineers at Meta, Google LLC and Spotify Technology SA, and Conductor now says more than 100,000 people use it. The startup, formally Melty Inc., was founded in 2024 by Chief Executive Charlie Holtz and Chief Technology Officer Jackson de Campos, and raised a $22 million Series A in March.

The deal fits a pattern: it landed the same day OpenAI said it plans to acquire developer tools startup Pierre Computer, and OpenAI had already announced plans in June to buy Ona, which runs coding agents in cloud sandboxes. Meta itself is leaning into coding — it released Muse Spark Open on Oct. 15, an open-weights version of its Muse Spark model aimed at coding and long-running agent work, while its more capable Muse Wonder models stay closed.

For existing users, the exit is staged. New sign-ups and downloads stopped today, Pro features are free, and the cloud service goes read-only on Nov. 13 before shutting on Nov. 20, when data deletion begins. Local Mac copies keep working until early 2027, though new models and critical bug fixes stop arriving then. Conductor said it has never sold user data or trained models on it.
