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.

01

How Clean maps into Attio

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.

  • Each lead becomes a person record, linked to a company record for its employer
  • Each saved Clean list becomes an Attio list of people with the same entries
  • Each custom Clean column becomes an attribute on people, with values written per person
  • Standard fields such as name, job title, email, and phone fill the matching Attio attributes
  • Leads that are only a company sync as company records, without a list entry
02

What happens after you connect

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.

03

Built so Attio stays yours

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.

  • Removing a lead from a Clean list removes only that list entry in Attio
  • Nothing in Attio is read back into Clean
  • Deals, notes, tasks, and custom objects are outside the sync
04

Where Clean's leads come from

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.

05

How to connect Attio to Clean

One member connects Attio for the whole workspace. Clean shows what it pushes and what it never does before you pick the Attio workspace.

  • Find Attio under CRM in Integrations. Open Integrations in your Clean workspace settings and choose Connect on the Attio row. The connection is shared by the whole workspace.
  • Choose the Attio workspace and approve access. Choose Connect with Attio, pick the Attio workspace on the next screen, and approve the access Clean asks for.
  • Watch the first sync fill Attio. Clean creates people, companies, lists, and attributes for what you already saved, then pushes new leads as you save them. The connection page shows the counts and the last sync time.

Common questions.

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.

How does Clean avoid duplicate records in Attio?

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.

What happens to my Clean columns in Attio?

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.

Whose leads sync to Attio?

Everyone's. Each Clean workspace has one Attio connection, shared by all of its members, and every lead saved in the workspace syncs.

What happens when I disconnect Attio?

Syncing stops and Clean drops its Attio access for everyone in the workspace. Everything already in Attio stays there.
