Why teams connect Attio and Clearbit
Run Attio and Clearbit side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
Clearbit is a read-only source: Stacksync reads its data in real time and delivers it into Attio, so Attio always reflects the current state of Clearbit — without exports, scripts, or schedulers.
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.
Common use cases
- 01 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- 02 Run a two-way dual-run when migrating to Attio from another CRM.
- 03 Route and score inbound demo requests using Clearbit company size and industry data synced into the CRM.
- 04 Refresh firmographic fields on existing accounts on a schedule so segmentation stays current.
Common sync patterns
Where both track pipeline: deal visibility across systems
Deal stage and value on shared accounts stay visible from either CRM.
Post-acquisition consolidation
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
Migration with a parallel run
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
What you can sync between Attio and Clearbit
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 | Clearbit objects | How this pairing syncs | |
|---|---|---|---|
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Companies Firmographic profiles looked up by domain and merged into account records. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Reveal matches IP-to-company resolutions used to identify anonymous website traffic. | Users is specific to Attio and Reveal matches to Clearbit — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Name-to-domain lookups Company name resolution used to normalize account records before enrichment. | Deals is specific to Attio and Name-to-domain lookups to Clearbit — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Enrichment attributes The firmographic and technographic fields appended to destination records. | Workspaces is specific to Attio and Enrichment attributes to Clearbit — each maps to any object or custom field on the other side. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Persons Individual profiles looked up by email and used to enrich contacts and leads. | Custom objects is specific to Attio and Persons to Clearbit — each maps to any object or custom field on the other side. |
How changes propagate between Attio and Clearbit
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Attio Clearbit Sub-second propagation
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryClearbit does not accept inbound record writes, so this direction carries requests rather than records: Clearbit's output flows back as field updates on the originating Attio records.
Clearbit Attio Sub-second propagation
DetectionClearbit notifies Stacksync of record changes through webhook events. On-demand lookups.
DeliveryEach detected change is written to Attio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Attio: Subject to the platform's published API rate limits.
- Clearbit: Subject to plan-based API rate limits and lookup volumes.

FAQ
Attio and Clearbit integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Attio and Clearbit — Clearbit is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. On Clearbit: On-demand lookups; asynchronous enrichment results can be delivered via webhook callbacks. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Attio side: Custom objects, People, Companies, Users, plus custom fields where Attio exposes them. On the Clearbit side: Reveal matches, Name-to-domain lookups, Enrichment attributes, Companies. Stacksync auto-detects both schemas and converts types between the two systems.
-
Clearbit is a read-only source, so this integration runs one-way: Stacksync reads from Clearbit in real time and delivers into Attio. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for Attio and Clearbit: Where both track pipeline: deal visibility across systems; Post-acquisition consolidation; Migration with a parallel run. Deal stage and value on shared accounts stay visible from either CRM.
