# 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/opennous) to follow along.

## 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.

The account is computed and kept current ahead of time, so your agent never searches and reassembles it. It reads the resolved account and acts.

## What a context graph models

A context graph models your market the way a good rep reasons about it.

* **Entities.** The accounts and the people.
* **Relationships.** Who owns the account, who is the champion, who is the blocker.
* **Claims.** What is true, and how sure we are.
* **Signals.** What is happening right now.

Nous ships this graph pre-built for GTM, so you never start from an empty model. Every outcome you record feeds back, so the account gets truer and the ICP model sharpens from your own won and lost deals.

## What you get

* **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.
