Why teams connect Intercom and ZoomInfo

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

ZoomInfo is a read-only source: Stacksync reads its data in real time and delivers it into Intercom, so Intercom always reflects the current state of ZoomInfo — without exports, scripts, or schedulers.

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.

Common use cases

  • Route qualified leads from Intercom conversations into the CRM as leads or opportunities in near real time
  • Sync contacts and companies bi-directionally with the CRM so support sees deal context and sales sees conversation history
  • Fill gaps in new lead records (email, phone, company size) as they enter the CRM.
  • Feed technographic data into territory plans or scoring models in a warehouse.

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.
