One source of truth for who you sell to
Accounts, contacts, deals and signals live in one typed model. Your ICP, scoring and voice are defined once, and every engine obeys.
Self-hosted. Agent-first. Approved by people.
Your go-to-market, run by agents you can trust.
GTM OS is a self-hosted operating system for go-to-market that keeps one typed record of who you sell to, runs the engines that find, score, route and reach them, and lets your agents act only after a second person approves.
$ npm i -g @gtmos/cli $ gtm init
Needs a human Example, simplified
Send first email to the buying committee
Proposed by an agent for Acme. Claims checked against your proof library.
Waiting for approvalDry Mode on
Move budget to the better channel
The allocator proposes. It cannot execute.
Approved by a second person
Merge two duplicate accounts
Undo stays available after the merge.
Reviewed
Four gains, from the first day
Built for GTM engineers who wire the system and strategists who run it.
Agents that never act alone
Anything that leaves the building waits for a second person. The proposer can never approve their own action.
Safe by default with Dry Mode
Start in Dry Mode, see exactly what would have happened, then go live one engine at a time with caps and quiet hours.
Updates that never touch your data
Every upgrade takes a verified backup first and adds only. If a step fails, you roll back to where you were.
Install and upgrade
You need Docker Desktop, Node 22 or later, and Claude Code, which runs the setup with you.
Install
$ npm i -g @gtmos/cli $ mkdir my-gtm && cd my-gtm $ gtm init
Release 0.2.5 (rolling out). Until it is published, this installs the previous release.
Open Claude Code in that folder and run /setup-gtmos. Claude asks only for what a person has to provide.
Upgrade
$ npm i -g @gtmos/cli@latest $ gtm upgrade --check $ gtm upgrade --channel stable --yes
Release 0.2.5 (rolling out). Until it is published, this upgrades to the previous release.
Upgrade the CLI first. Upgrades snapshot your data first, and --dry-run rehearses one. A pinned install only moves when you choose --channel or --to.
