How Horison works
Put the work in one place. Ask questions of it. Let an agent write against it.
The idea
A private-markets team already has a CRM, a shared drive, and a pile of PDFs. Horison is the place those things meet so you can work a deal without hopping tools for every question.
A file you add to a deal is processed: split up, read, and written onto a knowledge graph with the page it came from. A connector (Attio, Drive, Gmail) brings in records or lets Chat and agents use that system as a tool. Chat, an in-product agent, and Claude connected over MCP all read the same graph. Nobody is keeping a second copy of the truth.
What you can see is what your Horison login can see, at your firm. Another firm cannot see your graph. A personal Gmail connection cannot see a colleague’s inbox.
Inside the app
The left rail is the map. Documentation lives here, on a public URL, so someone without a session (an App Store reviewer, a new joiner, or an agent fetching the setup file) still has a page to read.
Workspace
Home, Search, Chat, Deals, Projects, Documents, Relationships, Agents, Knowledge graph.
Agents
Jobs that run in Horison: IC memos, screens, comparisons, and soon your own briefs.
Knowledge graph
Companies, people, metrics, and the excerpt that supports each fact.
Outside the app
Two kinds of system sit next to Horison and still talk to this record:
- Integrations in Settings: Gmail, Outlook, Drive, SharePoint, OneDrive, and Attio.
- Connect an agent: Claude, ChatGPT, or Cursor signing into Horison as you. That is not the Agents item on the rail, and it is not Attio’s CRM tools.
