Why teams connect Affinity and Apollo.io

Run Affinity and Apollo.io 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 Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io 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

  • Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.
  • Push enrichment data computed elsewhere into Affinity field values on list entries.
  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.

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.

What you can sync between Affinity and Apollo.io

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Affinity objects Apollo.io objects
Organizations Company records matched to accounts in other systems by domain. People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved.
Opportunities Deal records tracked on lists and synced with pipeline reporting. Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked.
Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record.
Notes Meeting and call notes synced for record-keeping in other systems. Tasks and calls Rep activity records synced for activity reporting and coaching workflows.
Interactions Automatically captured emails and meetings, read for activity reporting. Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync.
Reminders Follow-up tasks associated with people and organizations. Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields.
