**The product.** A desktop app for the Mac, and since July 2026 a cloud service, in which a developer starts several AI coding agents on the same code repository at once. Each agent gets its own workspace: a separate Git worktree with its own branch, files, terminal and chat. The developer watches what each agent does, reviews its changes, opens a pull request and merges it. Conductor runs the agents' own programs (Claude Code, Codex, Cursor and OpenCode) with the developer's own subscriptions or API keys, so it does not pay for the models. The local app was free; a Pro plan added cloud workspaces, the Conductor API and shared workspaces, and Team and Enterprise plans added company billing and administration.

**Why it worked.** Several agents that share one checkout of a repository edit the same files on disk. Conductor gave every agent its own working folder and branch through Git worktrees and put all the agents in one window, so one developer could run several tasks in parallel and review them one by one. The founder wrote that at the launch in July 2025, 'Writing most of your code with agents (let alone a team of coding agents) felt crazy'.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

Conductor is an app that runs several coding agents at once. A coding agent is a program built on a large language model that reads a code repository, edits files and runs commands to finish a programming task. Conductor gives each agent its own Git worktree, a second working folder attached to the same Git repository with its own branch, so agents can work in parallel without editing the same files. The developer then reviews each branch and turns it into a pull request, a proposed change that others can check before it is merged.

Charlie Holtz and Jackson de Campos founded it in 2024 and went through Y Combinator's Summer 2024 batch, according to Y Combinator's company page. The founder's announcement says Conductor launched in July 2025. On 30 July 2026 it added Conductor Cloud, which runs each agent in a cloud sandbox (an isolated virtual machine) and needed a paid Pro plan. Dealroom and AI Weekly reported a US$22 million Series A from Spark and Matrix in March 2026, and on 4 November 2026 the company announced that Conductor is joining Meta.

No revenue figure and no sale price were found, so this story has evidence grade E. The company's own pages show that it sold Pro subscriptions before the sale, but they do not publish the price or the number of paying users.

## Pricing

Conductor plans before the sale, from the company's Cloud FAQ, changelog and team-plan page, read 7 November 2026. No price amount is published on the pages read (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Free (local app) | 0 | 0 | runs on your Mac with your own agent subscriptions or keys |
| Pro |  | not published | cloud workspaces, Conductor API, shared workspaces with other Pro users |
| Team |  | not published (invite-only) | Pro features for a company, live collaboration, central billing, admin portal |
| Enterprise |  | not published | Team features plus automated user provisioning, a support SLA and security controls |

The local Mac app was free, and the developer paid the model providers through his or her own Claude, OpenAI or Cursor subscription or API key. Cloud workspaces needed a Pro, Team or Enterprise plan; the Cloud FAQ says cloud compute had no extra fee and that usage-based pricing was planned. Billing ran through a Stripe billing portal. Since 4 November 2026 new users cannot sign up, free users cannot upgrade, Pro users keep Pro features for free, and active Cloud subscribers are to get a refund.

## When did Conductor launch, and how did it grow? Timeline

From a Y Combinator company in 2024 to a sale to Meta in November 2026. Each entry carries its grade.

- **2024** (grade C [4, 3]): Charlie Holtz and Jackson de Campos found the company and join Y Combinator's Summer 2024 batch.
- **July 2025** (grade C [1, 10]): Conductor launches as a Mac app that runs several coding agents in parallel, each in its own Git worktree.
- **March 2026** (grade C [2, 3]): Dealroom and AI Weekly report a US$22 million Series A from Spark and Matrix.
- **30 July 2026** (grade C [7, 6]): Conductor Cloud and the Conductor API launch. Cloud workspaces need a Pro plan, billed through Stripe.
- **4 November 2026** (grade C [1, 2, 3]): The founder announces that Conductor is joining Meta. Terms are not disclosed. New sign-ups stop, and AI Weekly, citing Axios, reports that both founders join Meta Superintelligence Labs.
- **13 and 20 November 2026 (planned)** (grade C [1, 8]): Conductor Cloud goes read-only, then shuts down. The local app is to get new models and critical fixes until early 2027.

## Why did Conductor work?

### One worktree per agent

When a developer creates a workspace, Conductor creates a Git worktree and checks out a branch in it. Each agent edits its own files, and each branch becomes the unit that the developer reviews, pushes and turns into a pull request. That is what makes parallel agents on one repository possible.

### The agents and the models belong to someone else

Conductor bundles its own installation of Claude Code and Codex and uses Cursor and OpenCode through their integrations, with the tokens or API keys already on the developer's Mac. The developer pays the model providers directly, so the free local app carried no model cost for Conductor.

### Charge for what runs on Conductor's side

The paid Pro plan sold cloud workspaces that keep running when the laptop is closed, the Conductor API and shared workspaces. Team and Enterprise plans added live collaboration, central billing and administration, the parts that a company buys rather than a single developer.

## How it was built

These details come from the company's own documentation and release notes. They are grade C.

- A Mac desktop app. Each workspace is a Git worktree named after a city, which gives the files a stable folder that agents and other programs can find.
- It ships its own copies of Claude Code and Codex so that the versions stay compatible, and it signs in with the developer's existing Claude Pro or Max login, an API key, a Cursor API key or OpenCode.
- Conductor Cloud, launched on 30 July 2026, creates a Vercel Sandbox for each cloud workspace: 8 virtual CPUs, 16 GB of memory and 32 GB of temporary NVMe storage on Amazon Linux 2023. The FAQ says it was built in close collaboration with Vercel. Cloud workspaces support GitHub repositories only.
- The Conductor API lets users create workspaces, send prompts to the agent and read its replies from their own programs.
- Subscriptions are managed in the Stripe billing portal.
- Agents run with the user's own permissions on the Mac, without a sandbox, as the FAQ states.

## Who tried this before Conductor, and why did they fail?

Three developer-tool companies in our database of failed startups sold a better way to write code and lost to tools that larger companies gave away or bundled. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Kite DevTool (2014 to 2024; funding US$21M; cause: Competition)

- Promise: AI code completion inside the developer's editor, years before GitHub Copilot.
- Why it died: Could not make developers pay for a freemium tool, then GitHub Copilot arrived with GitHub's distribution and stronger OpenAI models.
- Record: 

### Nitrous.io (2012 to 2016; funding US$8M; cause: Competition)

- Promise: Instant cloud development environments, so code runs the same everywhere and new team members start at once.
- Why it died: Amazon bought the competitor Cloud9 and gave it away, while Nitrous tried to sell what the large platforms bundled.
- Record: 

### Light Table/Eve (2012 to 2015; funding US$3M; cause: Competition)

- Promise: A code editor with live feedback on what the code does, then a new way for non-programmers to build apps.
- Why it died: Developers stayed with the mainstream editors, and the company could not turn a new editor into a business.
- Record: 

## What changed

Each of the three sold a better developer workspace and lost when a large company bundled a similar tool or gave it away. Conductor faced a similar risk: it depended on agents made by the model companies, which decide how those agents work.

Two things differed. Conductor did not build its own model or agent; it ran the agents that the providers already sell and let the developer pay for them, so the free app carried no model cost. And it was bought by a large AI company early, 16 months after launch according to the founder's dates, instead of competing with the providers for years.

## Can one person copy Conductor now?

**Verdict: The product, yes. The outcome, not by plan.**

The core idea, one Git worktree per agent around agent programs that developers already pay for, uses standard Git features and the agents' own command-line programs, so one developer can build a first version. The sale to Meta came after a Y Combinator batch, a reported Series A and a team of about eight; Dealroom reported that people familiar with the deal expect Conductor's product work to support Meta's next AI coding products.

1. Build on the agents developers already pay for, and let them bring their own subscriptions and keys, so models are never your cost.
2. Solve one concrete conflict, such as two agents editing the same files, with a standard mechanism like Git worktrees.
3. Keep the local app free and charge for what you must run yourself: cloud machines, an API and collaboration.
4. Ship and publish release notes often; the company's changelog reached version 0.93 in 16 months.

**What is still open.** Tools around coding agents that the model providers do not build themselves: review of agent work, testing, team dashboards and agents on other Git hosts than GitHub.

## What could go wrong for Conductor?

- **What is not verified.** No revenue figure, number of paying users, Pro price or sale price was found. The sale rests on the founder's announcement on the company site and on reports by Dealroom and AI Weekly; no statement written by Meta was read, and the Axios report that AI Weekly cites returned 403. The US$22 million Series A of March 2026 is reported by Dealroom and AI Weekly only. The home page shows 'Trusted by 100k+ builders' next to logos of Linear, Vercel, Notion, Ramp, Y Combinator, Square, PostHog and Spotify, with no source or customer story for most of them, a first-name testimonial and a 'SOC 2 Type II' badge with no link to a report. The general FAQ still answers 'How does Conductor make money?' with 'Right now we don't', while the Cloud FAQ and release notes describe paid Pro, Team and Enterprise plans. Looked for: a payment-processor profile, a founder interview with figures, Meta's own announcement. A reader could look for a Meta filing or press statement on the deal.
- **Team size, funding and the wind-down.** Two founders started it in 2024. Y Combinator's page lists a team of 8, with no date. AI Weekly, citing Axios, reports that both founders join Meta Superintelligence Labs. The product is closing: no new sign-ups since 4 November 2026, Conductor Cloud shuts down on 20 November 2026, and the local app gets updates until early 2027, according to the founder's announcement.
- **Competition.** Other developer-tool stories on this site also sit on top of coding agents, for example Omnara, which started as a web and mobile remote control for Claude Code, and Repo Prompt, a Mac app that selects the files of a repository for a model; Conductor differs in running several agents at once in separate worktrees. Dealroom notes that on the same day OpenAI said it plans to acquire another developer-tools startup.
- **Dependence on model providers.** Conductor ran Anthropic's Claude Code, OpenAI's Codex, Cursor and OpenCode with the user's own subscriptions and keys, according to its home page and FAQ, and its cloud ran on Vercel Sandbox. A change in those providers' terms, prices or features could have removed the reason to use it. AI Weekly asks whether Meta will keep support for the other providers' agents.
