Why teams connect 6sense and Apollo.io

Run 6sense 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.

6sense is a read-only source: Stacksync reads its data in real time and delivers it into Apollo.io, so Apollo.io always reflects the current state of 6sense — without exports, scripts, or schedulers.

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.

Common use cases

  • Pull segment membership into a marketing automation platform to trigger campaigns when accounts enter a segment.
  • Land account-level intent data in a warehouse to join with pipeline data for ABM reporting.
  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.

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 6sense 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.

6sense objects Apollo.io objects
Intent Signals Keyword-level research activity used to flag in-market accounts. Accounts Company records with firmographic attributes, matched to CRM accounts during sync.

Reach Scores Model scores reflecting the level and recency of outreach to an account or contact, used to prioritize follow-up. Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked.
Accounts Company records enriched with firmographics and intent data, matched to CRM accounts. Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record.
Segments Dynamic account lists built from intent and fit criteria, read out to drive targeting. Tasks and calls Rep activity records synced for activity reporting and coaching workflows.
