Why teams connect DealCloud and HubSpot
Run DealCloud and HubSpot side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
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.
Stacksync syncs Company, Contact, Fund, Investment in DealCloud with Contact, Company, Deal, Line Item in HubSpot in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Common use cases
- 01 Mirror DealCloud activities and tasks into an operational database to power internal dashboards without hitting the API on every read.
- 02 Push portfolio and fund performance data from a warehouse into DealCloud so dealmakers see up-to-date metrics on each investment.
- 03 Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
- 04 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
Common sync patterns
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.
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.

How changes propagate between DealCloud and HubSpot
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.
DealCloud HubSpot Interval-based propagation
DetectionStacksync polls DealCloud for changes on an incremental schedule, reading only records changed since the previous pass. Incremental via each entry's last-modified timestamp.
DeliveryEach detected change is written to HubSpot through its API, with automatic retries and rate-limit backoff.
HubSpot DealCloud Sub-second propagation
DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.
DeliveryEach detected change is written to DealCloud through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- DealCloud: API request limits apply per firm tenant; Stacksync manages throttling and retries automatically.
- HubSpot: Request limits vary by subscription tier and API type.

DealCloud: DealCloud's data model is fully configurable: each firm defines its own entry types (objects) and fields, so syncs map to a firm-specific schema rather than a fixed one. HubSpot: All CRM objects share a single property-based schema model, and relationships are expressed as typed associations rather than foreign keys, so syncs replicate associations explicitly. Stacksync's field mapping accounts for these differences between DealCloud and HubSpot without custom code.
