Why teams connect Intercom and Salesloft

Run Intercom 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 Admins & Teams, Articles, Contacts, Companies in Intercom with Tasks, Meetings, Users, Custom Fields 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

  • 01 Route qualified leads from Intercom conversations into the CRM as leads or opportunities in near real time
  • 02 Sync contacts and companies bi-directionally with the CRM so support sees deal context and sales sees conversation history
  • 03 Write email and call activity back to the CRM or a Postgres table for a complete engagement timeline.
  • 04 Keep person and account custom fields populated from an enrichment pipeline for personalization tokens.

Common sync patterns

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.
