Two-way sync
Changes in Apollo.io or Streak CRM instantly reflect in both systems. No stale data, no manual imports.
Keep Apollo.io 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 Contacts, Accounts, People (database records), Sequences in Apollo.io with Stages, Contacts, Organizations, Tasks 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.
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
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.
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.
| Apollo.io objects | Streak CRM objects | How this pairing syncs | |
|---|---|---|---|
| Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. | Contacts People linked to boxes, synced with marketing and support tools. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. | Custom fields Per-pipeline field definitions that determine what data a box can hold. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Tasks and calls Rep activity records synced for activity reporting and coaching workflows. | Organizations Company records associated with contacts and boxes. | Tasks and calls is specific to Apollo.io and Organizations to Streak CRM — each maps to any object or custom field on the other side. | |
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Tasks To-dos attached to boxes for follow-up tracking. | Accounts is specific to Apollo.io and Tasks to Streak CRM — each maps to any object or custom field on the other side. | |
| People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. | Email threads Gmail threads linked to boxes, since the CRM lives inside the inbox. | People (database records) is specific to Apollo.io and Email threads to Streak CRM — each maps to any object or custom field on the other side. | |
| Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. | Pipelines Define the process and the custom field schema that boxes in them carry. | Sequences is specific to Apollo.io and Pipelines to Streak CRM — each maps to any object or custom field on the other side. |
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.
DeliveryEach detected change is written to Streak CRM through its API, with automatic retries and rate-limit backoff.

Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and Streak CRM: authenticate both systems, choose the objects to sync (such as Apollo.io's Contacts and Custom fields), map fields visually, and changes propagate both ways in milliseconds — no code required.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Apollo.io and Streak CRM records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apollo.io and Streak CRM connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apollo.io–Streak CRM integration in-house.
Yes — Stacksync ships production-grade connectors for both Apollo.io and Streak CRM. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Apollo.io: Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream. 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 Apollo.io side: Contacts, Accounts, People (database records), Sequences, plus custom fields where Apollo.io exposes them. On the Streak CRM side: Stages, Contacts, Organizations, Tasks. Stacksync auto-detects both schemas and converts types between the two systems.
