# Introduction

> Welcome to Nous documentation

<Note>
  Nous is open source under AGPL v3. Self-host with [Docker Compose](/installation/docker-compose), or [try Nous](https://app.opennous.cloud) if you'd rather skip the setup. ⭐ the repo on [GitHub](https://github.com/NousC/nous) to follow along.
</Note>

## What is Nous?

Nous is **the context graph for GTM agents**. It resolves every person, conversation, and touchpoint across your GTM tool stack (Apollo, HubSpot, Smartlead, Gmail, LinkedIn) into one account record, returned to an agent in a single MCP call.

* **One account record.** Every contact, channel, and touch at an account, merged into a single source of truth.
* **Agent-ready.** The full account returned in one MCP call as structured context, never a raw data dump.
* **Live sync.** Outbound tools, communications, and CRM stay in lockstep, bi-directionally.
* **Open by default.** AGPL v3, self-host free forever, or skip the setup with Nous Cloud.
