Why teams connect Apollo.io and Twenty CRM
Run Apollo.io 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 Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with Tasks, Notes, Custom Objects, Attachments 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
- Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
- Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
- Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
- Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.
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.
