Does Clean sync data from Attio back into Clean?
No. The sync runs in one direction, from Clean into Attio. Changes your team makes in Attio stay in Attio and are not copied into Clean, and Clean never deletes an Attio record.
Integration
Push the leads, lists, and columns you save in Clean into Attio, automatically. People and companies arrive as Attio records, saved lists become Attio lists, and your custom columns become attributes your team can filter on.

The short answer
Clean's Attio integration mirrors your Clean workspace into Attio in one direction. After you connect an Attio workspace, every lead becomes a person record linked to its company, every saved list becomes an Attio list, and every custom column becomes a people attribute. Clean updates what it created, never deletes Attio records, and never reads Attio back.
Attio is built around records, lists, and attributes, and Clean's leads map onto each. The mapping is fixed, so nobody has to design fields or objects before the first sync.
Connecting starts a backfill of everything already saved in Clean. From then on, saving a lead in Clean pushes that person, their company, and their list entries. Edits in Clean are patched onto the record, and a regular reconcile catches values that changed without a direct edit.
Attio remains the system your team works in. Clean matches people by email address and companies by domain, so an existing Attio record is updated instead of duplicated. It never deletes a person, company, or list in Attio, and archiving a column in Clean archives the matching attribute, which you can restore.
The records Clean pushes into Attio start from real-world evidence of what companies actually do: government filings, trade and shipping records, fleet and safety records, company sites, and trade press, together with Clean's own datasets and licensed company data. Clean names the right people at each company, and Attio receives them ready to work.
One member connects Attio for the whole workspace. Clean shows what it pushes and what it never does before you pick the Attio workspace.
The Attio connection at a glance
| Attio | |
|---|---|
| Pushes | Every lead and its company, every saved list as an Attio list, and every custom column as an attribute on people. Edits made in Clean follow. |
| Never | Deletes people, companies, or lists in Attio, or reads Attio back into Clean. |
| Shares with | The whole workspace: one connection, everyone's leads. |
| On disconnect | Stops syncing and drops Attio access. Everything already in Attio stays there. |
No. The sync runs in one direction, from Clean into Attio. Changes your team makes in Attio stay in Attio and are not copied into Clean, and Clean never deletes an Attio record.
Clean matches people by email address and companies by domain before it creates anything, so a person or company that already exists in Attio is updated rather than duplicated.
Each live custom column becomes an attribute on the people object, and its values are written per person. Archiving a column in Clean archives the attribute in Attio, which you can restore.
Everyone's. Each Clean workspace has one Attio connection, shared by all of its members, and every lead saved in the workspace syncs.
Syncing stops and Clean drops its Attio access for everyone in the workspace. Everything already in Attio stays there.
