Why teams connect Clearbit and HubSpot

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

Clearbit 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 Clearbit — 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 and score inbound demo requests using Clearbit company size and industry data synced into the CRM.
  • Refresh firmographic fields on existing accounts on a schedule so segmentation stays current.
  • 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.

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.
