Why teams connect Affinity and Twenty CRM

Run Affinity and Twenty CRM 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 Lists, List Entries, Persons, Organizations in Affinity with Notes, Custom Objects, Attachments, Workspace Members in Twenty CRM 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

  • Sync notes and reminders into project or task systems used outside the deal team.
  • Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.
  • Mirror support tickets or tasks between Twenty and an operations tool.
  • Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.

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.
