Why teams connect Affinity and HubSpot

Run Affinity 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 Notes, Interactions, Reminders, Lists in Affinity with Stages, Audit, Contact, Company 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

  • 01 Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.
  • 02 Push enrichment data computed elsewhere into Affinity field values on list entries.
  • 03 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • 04 Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.

Common sync patterns

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.

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.
