Why teams connect Affinity and Crustdata
Run Affinity 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 Affinity, so Affinity 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 Sync notes and reminders into project or task systems used outside the deal team.
- 02 Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.
- 03 Fill missing contact fields on CRM people records from Crustdata profiles instead of manual research.
- 04 Stream screener results into a warehouse to maintain a living TAM and target-account universe.
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 Affinity 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.
| Affinity objects | Crustdata objects | How this pairing syncs | |
|---|---|---|---|
| Organizations Company records matched to accounts in other systems by domain. | 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. | Organizations is specific to Affinity and Screener Results to Crustdata — each maps to any object or custom field on the other side. | |
| Opportunities Deal records tracked on lists and synced with pipeline reporting. | 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. | Opportunities is specific to Affinity and Enrichment Responses to Crustdata — each maps to any object or custom field on the other side. | |
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. | Companies Firmographic records — industry, size, funding, growth signals; read out to enrich CRM accounts and warehouse company tables. | Field Values is specific to Affinity and Companies to Crustdata — each maps to any object or custom field on the other side. | |
| Notes Meeting and call notes synced for record-keeping in other systems. | People Contact and profile data for decision-makers; read into a CRM or outreach tool to fill missing titles, emails, and LinkedIn profiles. | Notes is specific to Affinity and People to Crustdata — each maps to any object or custom field on the other side. | |
| Interactions Automatically captured emails and meetings, read for activity reporting. | Headcount and Growth Metrics Time-series employee counts by department and region; read to score accounts on hiring momentum and expansion signals. | Interactions is specific to Affinity and Headcount and Growth Metrics to Crustdata — each maps to any object or custom field on the other side. | |
| Reminders Follow-up tasks associated with people and organizations. | Tech Stack Detected technologies per company; read to build segments and route accounts by the tools they already use. | Reminders is specific to Affinity and Tech Stack to Crustdata — each maps to any object or custom field on the other side. |
How changes propagate between Affinity 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.
Affinity Crustdata Sub-second propagation
DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.
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 Affinity records.
Crustdata Affinity 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 Affinity through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Affinity: Subject to the platform's published API rate limits.
- 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.
