OpenNous is open source. The server is AGPL-3.0 and the MCP server and CLI are Apache-2.0. Self-host with Docker Compose, or use OpenNous Cloud. The code is on GitHub. See Cloud vs self-host.

​
What is OpenNous?

OpenNous is the open-source revenue context graph. It resolves every person, conversation, and touchpoint across your GTM tools (HubSpot, Salesforce, Gmail, Smartlead, LinkedIn, your call recorder) into one account record, returned to an agent in a single MCP or REST 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 revenue context graph models

A revenue 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.
OpenNous 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 source. Self-host it for free, or skip the setup with OpenNous Cloud.
