# What is firm os?

> A workspace for VC and PE firms that runs in the firm's own Cloudflare account. It is in closed beta with Railblocks' clients, and installs are by invite.

firm os is a workspace for venture capital and private equity firms: one place for the firm's deals, people and knowledge, with apps and agents on top. It runs in the firm's own Cloudflare account, not in an account the maintainers run.

## Who it is for

Partners, investment teams, and the operations people who run a firm's systems. An agent can prepare an install for a firm, but a person at the firm approves it on a Cloudflare page ([for agents](https://firmos.railblocks.com/docs/for-agents)).

## Where it runs

- **In the firm's own Cloudflare account.** The installer puts nine Workers, three key-value stores, one R2 bucket and a sign-in app into the one account the firm picks ([install](https://firmos.railblocks.com/docs/install)).
- **Behind Cloudflare Access.** People sign in with their email and a code Cloudflare sends them. Only people at the firm's email domains, and people the firm names, get in.
- **With no standing access for the installer.** The installer revokes its key to the account when the install ends, so it can no longer reach the account ([security](https://firmos.railblocks.com/docs/security)).

## What it is made of

- Cloudflare OS, unmodified: workspaces, apps, chats with an agent, and gatekeepers, the doors to outside systems.
- A web app at `/firm/` on the firm's address.
- Blocks: apps for the investment lifecycle that a workspace can add.
- Jev, which labels records, and each person's private desk.

A Mac app signs in to the same address. It is not part of the install.

## Status

- **Closed beta:** firm os runs with Railblocks' existing clients. Cloudflare bills the firm for what runs in its account ([cost](https://firmos.railblocks.com/docs/cost)).
- **Installs:** by invite. The front page takes an email from anyone who wants to start.
