Why teams connect 6sense and Close

Run 6sense and Close 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 Close, so Close 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

  • 01 Pull segment membership into a marketing automation platform to trigger campaigns when accounts enter a segment.
  • 02 Land account-level intent data in a warehouse to join with pipeline data for ABM reporting.
  • 03 Push call, SMS, and email activity data into a warehouse for rep performance and outreach-cadence analysis.
  • 04 Write product usage or firmographic data from an internal database onto Close lead custom fields to prioritize follow-up.

Common sync patterns

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.

How changes propagate between 6sense and Close

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.

6sense Close Interval-based propagation

DetectionStacksync polls 6sense for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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

Close 6sense Sub-second propagation

DetectionClose notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling on date_updated fields for backfills.

Delivery6sense does not accept inbound record writes, so this direction carries requests rather than records: 6sense's output flows back as field updates on the originating Close records.

Rate-limit considerations

  • 6sense: Subject to the platform's API rate limits, which vary by contracted API package.
  • Close: Subject to per-endpoint rate limits communicated in response headers.
