Why teams connect Kustomer and Salesloft

Run Kustomer 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 Users, Teams, Tags, Notes in Kustomer with Custom Fields, People, Accounts, Cadences 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

  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Keep person and account custom fields populated from an enrichment pipeline for personalization tokens.
  • Reconcile ownership by syncing user assignments between the CRM and Salesloft.

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.

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.
