Why teams connect DuckDB and HubSpot

Treat HubSpot like part of your database: its records live in DuckDB as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in DuckDB, where it can be queried and joined like everything else.

Stacksync mirrors Contact, Company, Deal, Line Item from HubSpot into External files (Parquet/CSV/JSON), Attached databases, Database files, Schemas in DuckDB with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in HubSpot with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.

Query the CRM like a database

Accounts, contacts, and custom objects from HubSpot become tables in DuckDB you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to DuckDB sync onto the matching records in HubSpot, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the HubSpot API, limits, and retries.
