Why teams connect Clearbit and Greenhouse
Flow Clearbit data into Greenhouse in real time — no exports, no schedulers, no custom scripts.
Clearbit 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 Clearbit — without exports, scripts, or schedulers.
Clearbit 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 Route and score inbound demo requests using Clearbit company size and industry data synced into the CRM.
- 02 Refresh firmographic fields on existing accounts on a schedule so segmentation stays current.
- 03 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.
- 04 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update stage, status, and custom fields in SQL while recruiters stay in Greenhouse.
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 Clearbit, 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 Clearbit, so a new rep can start working accounts without waiting on a manual setup ticket.
What you can sync between Clearbit 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.
| Clearbit objects | Greenhouse objects | How this pairing syncs | |
|---|---|---|---|
| Companies Firmographic profiles looked up by domain and merged into account records. | Applications Links a Candidate to a Job; carries current stage, status, and source. Movable, rejectable, and hireable through Harvest write calls. | Companies is specific to Clearbit and Applications to Greenhouse — each maps to any object or custom field on the other side. | |
| Persons Individual profiles looked up by email and used to enrich contacts and leads. | Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. | Persons is specific to Clearbit and Jobs to Greenhouse — each maps to any object or custom field on the other side. | |
| Reveal matches IP-to-company resolutions used to identify anonymous website traffic. | Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. | Reveal matches is specific to Clearbit and Offers to Greenhouse — each maps to any object or custom field on the other side. | |
| Name-to-domain lookups Company name resolution used to normalize account records before enrichment. | Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. | Name-to-domain lookups is specific to Clearbit and Scorecards to Greenhouse — each maps to any object or custom field on the other side. | |
| Enrichment attributes The firmographic and technographic fields appended to destination records. | Scheduled Interviews Interview events with interviewers, times, and rooms; full create/update/delete support for calendar and reporting syncs. | Enrichment attributes is specific to Clearbit and Scheduled Interviews to Greenhouse — each maps to any object or custom field on the other side. |
How changes propagate between Clearbit 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.
Clearbit Greenhouse Sub-second propagation
DetectionClearbit notifies Stacksync of record changes through webhook events. On-demand lookups.
DeliveryEach detected change is written to Greenhouse through its API, with automatic retries and rate-limit backoff.
Greenhouse Clearbit 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 /.
DeliveryClearbit does not accept inbound record writes, so this direction carries requests rather than records: Clearbit's output flows back as field updates on the originating Greenhouse records.
Rate-limit considerations
- Clearbit: Subject to plan-based API rate limits and lookup volumes.
- 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.

FAQ
Clearbit and Greenhouse integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Clearbit and Greenhouse — Clearbit 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.
-
Clearbit: Lookups can resolve asynchronously: the API may accept a request and deliver the completed record later via webhook, which sync logic must accommodate. Greenhouse: Pagination is Link-header (RFC-5988) based with per_page between 1 and 500 (default 100). Stacksync's field mapping accounts for these differences between Clearbit and Greenhouse without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Clearbit and Greenhouse records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Clearbit and Greenhouse connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Clearbit–Greenhouse integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Clearbit and Greenhouse. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Clearbit: On-demand lookups; asynchronous enrichment results can be delivered via webhook callbacks. On Greenhouse: HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after / last_activity_after filters. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
