Why teams connect Outreach and Twenty CRM

Run Outreach 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 Sequence states, Mailings, Calls, Tasks in Outreach with People, Companies, Opportunities, Tasks 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

  • Suppress prospects across systems when a contact unsubscribes or a customer churns.
  • Enroll leads in sequences automatically by writing sequence-state records when a lead crosses a scoring threshold in the warehouse.
  • Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.
  • Push product usage or billing data from a warehouse into Twenty custom fields to give reps account context.

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.
