Why teams connect Close and Crustdata
Run Close and Crustdata side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
Crustdata 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 Crustdata — 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 Push call, SMS, and email activity data into a warehouse for rep performance and outreach-cadence analysis.
- 02 Write product usage or firmographic data from an internal database onto Close lead custom fields to prioritize follow-up.
- 03 Enrich CRM accounts with firmographics, headcount growth, and tech stack so scoring and routing run on complete data.
- 04 Fill missing contact fields on CRM people records from Crustdata profiles instead of manual research.
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.
What you can sync between Close and Crustdata
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.
| Close objects | Crustdata objects | How this pairing syncs | |
|---|---|---|---|
| Activities Calls, emails, SMS, notes, and meetings logged against a lead; the source for engagement analytics. | Companies Firmographic records — industry, size, funding, growth signals; read out to enrich CRM accounts and warehouse company tables. | Activities is specific to Close and Companies to Crustdata — each maps to any object or custom field on the other side. | |
| Tasks Follow-up items assigned to users; synced for workload and SLA reporting. | People Contact and profile data for decision-makers; read into a CRM or outreach tool to fill missing titles, emails, and LinkedIn profiles. | Tasks is specific to Close and People to Crustdata — each maps to any object or custom field on the other side. | |
| Custom Activities User-defined activity types with their own custom fields, mapped like standard activities. | Headcount and Growth Metrics Time-series employee counts by department and region; read to score accounts on hiring momentum and expansion signals. | Custom Activities is specific to Close and Headcount and Growth Metrics to Crustdata — each maps to any object or custom field on the other side. | |
| Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs. | Tech Stack Detected technologies per company; read to build segments and route accounts by the tools they already use. | Custom Fields is specific to Close and Tech Stack to Crustdata — each maps to any object or custom field on the other side. | |
| Users Sales reps referenced as owners on leads, opportunities, and activities. | Screener Results Saved company searches with filter criteria; read on a schedule so target-account lists in the CRM refresh as companies enter the criteria. | Users is specific to Close and Screener Results to Crustdata — each maps to any object or custom field on the other side. | |
| Smart Views Saved lead searches that can scope which records a segment-based sync pulls. | Enrichment Responses Real-time enrichment lookups keyed by domain or profile URL; read to append fresh firmographic and contact data at form-fill or record-creation time. | Smart Views is specific to Close and Enrichment Responses to Crustdata — each maps to any object or custom field on the other side. |
How changes propagate between Close and Crustdata
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.
Close Crustdata 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.
DeliveryCrustdata does not accept inbound record writes, so this direction carries requests rather than records: Crustdata's output flows back as field updates on the originating Close records.
Crustdata Close Interval-based propagation
DetectionStacksync polls Crustdata for changes on an incremental schedule, reading only records changed since the previous pass. Pull-based: real-time enrichment endpoints for on-demand lookups plus periodic re-pulls of screeners and datasets.
DeliveryEach detected change is written to Close through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Close: Subject to per-endpoint rate limits communicated in response headers.
- Crustdata: Requests are metered by plan credits and per-minute rate limits; bulk dataset pulls are the efficient path for large refreshes rather than per-record enrichment calls.
