Why teams connect Affinity and Outreach

Run Affinity and Outreach 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 Organizations, Opportunities, Field Values, Notes in Affinity with Users, Mailboxes, Prospects, Accounts in Outreach 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 Sync notes and reminders into project or task systems used outside the deal team.
  • 02 Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.
  • 03 Pull mailing, call, and task activity into a database for engagement analytics beyond native reports.
  • 04 Keep account ownership and stages aligned between Outreach and the CRM as territories change.

Common sync patterns

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.
