Why teams connect Close and HubSpot

Run Close and HubSpot 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 Custom Activities, Custom Fields, Users, Smart Views in Close with Pipeline, Stages, Audit, Contact in HubSpot 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

  • Keep Close contacts aligned with a marketing automation platform so outreach lists stay current.
  • Push call, SMS, and email activity data into a warehouse for rep performance and outreach-cadence analysis.
  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • Sync HubSpot Tickets with an internal support database to unify service reporting across channels.

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.
