Why teams connect 6sense and Greenhouse
Flow 6sense data into Greenhouse in real time — no exports, no schedulers, no custom scripts.
6sense is a read-only source: Stacksync reads its data in real time and delivers it into Greenhouse, so Greenhouse always reflects the current state of 6sense — without exports, scripts, or schedulers.
6sense runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Greenhouse. Greenhouse is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.
Common use cases
- 01 Sync 6sense buying stage and intent scores onto CRM accounts so sellers prioritize in-market targets.
- 02 Pull segment membership into a marketing automation platform to trigger campaigns when accounts enter a segment.
- 03 Stream Jobs, Departments, and Offices into a reporting database for recruiting funnel and time-to-fill dashboards.
- 04 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.
Common sync patterns
One directory of people
A person's name, title, email, phone, or manager corrected in either system updates the other, so both stop maintaining separate copies of the same individual.
Where Greenhouse tracks people the business also engages: contacts stay in sync
A person recorded in Greenhouse, such as a candidate or applicant, can create or update the matching contact in 6sense, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.
New team members provisioned when they are hired
When Greenhouse records a new hire, a matching user or owner is created in 6sense, so a new rep can start working accounts without waiting on a manual setup ticket.
What you can sync between 6sense and Greenhouse
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 | Greenhouse objects | How this pairing syncs | |
|---|---|---|---|
| Accounts Company records enriched with firmographics and intent data, matched to CRM accounts. | Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. | Accounts is specific to 6sense and Departments and Offices to Greenhouse — 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. | Candidates Person records with contact details, tags, and custom fields; read and written via Harvest, often created from sourcing or enrichment pipelines. | Segments is specific to 6sense and Candidates to Greenhouse — 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. | Applications Links a Candidate to a Job; carries current stage, status, and source. Movable, rejectable, and hireable through Harvest write calls. | Buying Stage Scores is specific to 6sense and Applications to Greenhouse — each maps to any object or custom field on the other side. | |
| Intent Signals Keyword-level research activity used to flag in-market accounts. | Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. | Intent Signals is specific to 6sense and Jobs to Greenhouse — 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. | Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. | People / Contacts is specific to 6sense and Offers to Greenhouse — 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. | Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. | Reach Scores is specific to 6sense and Scorecards to Greenhouse — each maps to any object or custom field on the other side. |
How changes propagate between 6sense and Greenhouse
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 Greenhouse 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 Greenhouse through its API, with automatic retries and rate-limit backoff.
Greenhouse 6sense Sub-second propagation
DetectionGreenhouse notifies Stacksync of record changes through webhook events. HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after /.
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 Greenhouse records.
Rate-limit considerations
- 6sense: Subject to the platform's API rate limits, which vary by contracted API package.
- Greenhouse: Harvest enforces a per-integration limit over a rolling 10-second window (X-RateLimit-Limit, commonly 50 requests / 10s for approved integrations); responses carry X-RateLimit-Remaining and, on a 429, X-RateLimit-Reset and Retry-After.
