Architecture

One model for communication data.

Horato gives your product stable resources for messages, meetings, transcripts, contacts, tasks, bookings, webhooks, and agent actions. You keep the sync, audit, and repair details your product needs without owning every integration path.

01

Account connections

Connections, permissions, sync jobs, and capability checks live behind one product API.

02

Product resources

Email, calendar, meeting notes, contacts, tasks, scheduling, and webhooks share tenant-aware models your app can depend on.

03

Reliable delivery

Changes flow through an event log before signed webhooks are delivered, retried, and repaired.

04

Approved actions

REST, SDKs, and MCP tools use the same action model, with approvals for sends, bookings, event changes, and destructive operations.

Use cases

From first message to follow-up, keep the workflow connected.

Start with one communication workflow. Horato keeps email, calendars, meeting notes, tasks, bookings, and approvals tied to the same customer context.

Active customer path

Vertical SaaS

Add email, scheduling, contacts, tasks, and meeting notes without rebuilding the same integration work for every product line.

  4. 04Create follow-ups
Shared account context

REST, SDKs, webhooks, and MCP over the same model.

Backend teams can start with API keys and OAuth helpers, then use the same resource model through JavaScript, Python, webhooks, and MCP.
