Two-way sync
Changes in Attio or Intercom instantly reflect in both systems. No stale data, no manual imports.
Keep Attio and Intercom in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.
Stacksync syncs People, Companies, Users, Deals in Attio with Conversations, Tickets, Data Events, Custom Data Attributes in Intercom in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Deal stage and value on shared accounts stay visible from either CRM.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Attio objects | Intercom objects | |
|---|---|---|
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Conversations Support and sales threads sync outward for analytics and CRM context. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Tickets Structured ticket records track issues alongside conversational threads. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Data Events Behavioral events pushed in from product databases trigger messages and flows. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Custom Data Attributes Typed custom fields on contacts and companies hold synced billing and usage data. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Tags Labels applied to contacts, companies, and conversations sync for routing and reporting. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Segments Saved audience definitions are readable for targeting parity across tools. |

Yes. Stacksync provides a managed, real-time two-way integration between Attio and Intercom: authenticate both systems, choose the objects to sync (such as Attio's Custom objects and People), map fields visually, and changes propagate both ways in milliseconds — no code required.
Yes — Stacksync ships production-grade connectors for both Attio and Intercom. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. On Intercom: Webhook topic subscriptions for contact, company, and conversation events, plus polling for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Attio side: People, Companies, Users, Deals, plus custom fields where Attio exposes them. On the Intercom side: Conversations, Tickets, Data Events, Custom Data Attributes. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
