Two-way sync
Changes in Affinity or Streak CRM instantly reflect in both systems. No stale data, no manual imports.
Keep Affinity and Streak CRM in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 List Entries, Persons, Organizations, Opportunities in Affinity with Organizations, Tasks, Email threads, Custom fields in Streak 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.
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Deal stage and value on shared accounts stay visible from either CRM.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
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 | Streak CRM objects | |
|---|---|---|
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | Stages Pipeline steps whose transitions are the usual trigger for downstream syncs. | |
| Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. | Contacts People linked to boxes, synced with marketing and support tools. | |
| Organizations Company records matched to accounts in other systems by domain. | Organizations Company records associated with contacts and boxes. | |
| Opportunities Deal records tracked on lists and synced with pipeline reporting. | Tasks To-dos attached to boxes for follow-up tracking. | |
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. | Email threads Gmail threads linked to boxes, since the CRM lives inside the inbox. | |
| Notes Meeting and call notes synced for record-keeping in other systems. | Custom fields Per-pipeline field definitions that determine what data a box can hold. |

Change detection on Affinity: Webhook subscriptions for record events, supplemented by polling. On Streak CRM: Polling against pipeline, box, and contact endpoints; Streak's automations can send outbound webhooks on higher plans. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Affinity side: List Entries, Persons, Organizations, Opportunities, plus custom fields where Affinity exposes them. On the Streak CRM side: Organizations, Tasks, Email threads, Custom fields. Stacksync auto-detects both schemas and converts types between the two systems.
