Why teams connect Attio and Salesloft

Run Attio and Salesloft side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

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 Workspaces, Custom objects, People, Companies in Attio with People, Accounts, Cadences, Cadence Memberships in Salesloft 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.

Common use cases

  • Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.
  • Write product usage and enrichment data into Attio attributes so GTM teams work from live account signals.
  • Sync people, cadence memberships, and outcomes into a warehouse so RevOps can report on sequence performance next to pipeline data.
  • Auto-enroll leads into cadences when a row in an enrichment database meets a scoring condition.

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.

Divisional or regional split

Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
