Why teams connect HubSpot and ZoomInfo

Run HubSpot 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 HubSpot, so HubSpot 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

  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • Enrich CRM accounts and contacts on a schedule so firmographics, titles, and phone numbers stay current.
  • Sync intent signals into the CRM or warehouse to trigger outbound plays on in-market accounts.

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.

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.
