Why teams connect 6sense and Freshsales
Run 6sense and Freshsales 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 Freshsales, so Freshsales 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 Enrich inbound leads with 6sense firmographic and account-match data before routing.
- 02 Feed in-market account lists to sales engagement tools to start sequences automatically.
- 03 Sync deals into a data warehouse for pipeline reporting alongside product usage data.
- 04 Push product-qualified leads from the warehouse into Freshsales as contacts with lifecycle stages set.
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 6sense and Freshsales
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 | Freshsales objects | How this pairing syncs | |
|---|---|---|---|
| Accounts Company records enriched with firmographics and intent data, matched to CRM accounts. | Accounts Company records kept aligned with billing, ERP, and warehouse tables. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. | |
| Intent Signals Keyword-level research activity used to flag in-market accounts. | Deals Pipeline records synced to a warehouse for revenue reporting. | Intent Signals is specific to 6sense and Deals to Freshsales — each maps to any object or custom field on the other side. | |
| People / Contacts Persona and contact data surfaced for accounts, used to build outreach lists. | Tasks Rep to-dos created from external triggers or synced for productivity reporting. | People / Contacts is specific to 6sense and Tasks to Freshsales — each maps to any object or custom field on the other side. | |
| Reach Scores Model scores reflecting the level and recency of outreach to an account or contact, used to prioritize follow-up. | Appointments Scheduled meetings readable for activity analytics. | Reach Scores is specific to 6sense and Appointments to Freshsales — each maps to any object or custom field on the other side. | |
| Segments Dynamic account lists built from intent and fit criteria, read out to drive targeting. | Notes Free-text records attached to contacts, accounts, and deals. | Segments is specific to 6sense and Notes to Freshsales — each maps to any object or custom field on the other side. | |
| Buying Stage Scores Model-predicted stage per account, synced onto CRM records for prioritization. | Sales activities Configurable activity types logged against records, useful for engagement scoring. | Buying Stage Scores is specific to 6sense and Sales activities to Freshsales — each maps to any object or custom field on the other side. |
How changes propagate between 6sense and Freshsales
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 Freshsales 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 Freshsales through its API, with automatic retries and rate-limit backoff.
Freshsales 6sense Sub-second propagation
DetectionFreshsales notifies Stacksync of record changes through webhook events. Polling with updated-at filters through views.
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 Freshsales records.
Rate-limit considerations
- 6sense: Subject to the platform's API rate limits, which vary by contracted API package.
- Freshsales: Subject to per-account API rate limits that vary by Freshworks plan.

FAQ
6sense and Freshsales integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between 6sense and Freshsales — 6sense is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
On the 6sense side: Accounts, Segments, Buying Stage Scores, Intent Signals, plus custom fields where 6sense exposes them. On the Freshsales side: Sales activities, Products, Contacts, Accounts. Stacksync auto-detects both schemas and converts types between the two systems.
-
6sense is a read-only source, so this integration runs one-way: Stacksync reads from 6sense in real time and delivers into Freshsales. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for 6sense and Freshsales: Where both track pipeline: deal visibility across systems; Post-acquisition consolidation; Migration with a parallel run. Deal stage and value on shared accounts stay visible from either CRM.
-
6sense: REST API. Authentication: API key (token passed in request headers). Freshsales: REST API. Authentication: API key sent as a Token authorization header. Stacksync manages authentication, retries, and rate limits on both sides.
-
6sense: 6sense models classify accounts into predicted buying stages, and these stage values are the fields most teams sync into CRM and routing logic. Freshsales: Current Freshsales versions use lifecycle stages on contacts instead of a separate lead object, so lead routing maps to a stage field. Stacksync's field mapping accounts for these differences between 6sense and Freshsales without custom code.
