Why teams connect Apollo.io and Insightly

Run Apollo.io and Insightly 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 Deals (Opportunities), Tasks and calls, Custom fields, Contacts in Apollo.io with Notes, Products, Custom Fields, Contacts in Insightly 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

  • 01 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • 02 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 03 Deduplicate and align customer records between Insightly and an ERP or invoicing system
  • 04 Two-way sync of Insightly contacts and organizations with a marketing automation platform

Common sync patterns

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

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.

What you can sync between Apollo.io and Insightly

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 Insightly objects How this pairing syncs
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Contacts Person records sync with marketing and support tools to keep one contact list. 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-object custom fields carry enrichment and billing data written from external systems. 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.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved.

Projects Delivery records created from won opportunities sync with PSA and task tools. Sequences is specific to Apollo.io and Projects to Insightly — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Tasks Activity records keep follow-ups consistent across systems.

Apollo.io Insightly Interval-based propagation

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 Insightly through its API, with automatic retries and rate-limit backoff.

Insightly Apollo.io Interval-based propagation

DetectionStacksync polls Insightly for changes on an incremental schedule, reading only records changed since the previous pass. Polling on record updated-date fields.

DeliveryEach detected change is written to Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations
