Why teams connect 6sense and Twenty CRM
Run 6sense and Twenty CRM 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 Twenty CRM, so Twenty CRM 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 Feed in-market account lists to sales engagement tools to start sequences automatically.
- 02 Sync 6sense buying stage and intent scores onto CRM accounts so sellers prioritize in-market targets.
- 03 Sync Opportunities into a finance system to keep revenue forecasts current.
- 04 Mirror support tickets or tasks between Twenty and an operations tool.
Common sync patterns
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.
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.

How changes propagate between 6sense and Twenty CRM
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 Twenty CRM 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 Twenty CRM through its API, with automatic retries and rate-limit backoff.
Twenty CRM 6sense Sub-second propagation
DetectionTwenty CRM notifies Stacksync of record changes through webhook events. Webhooks on record create, update, and delete events, or polling on record update timestamps.
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 Twenty CRM records.
Rate-limit considerations
- 6sense: Subject to the platform's API rate limits, which vary by contracted API package.
- Twenty CRM: Subject to the platform's API rate limits; self-hosted deployments control their own limits.
