Why teams connect DuckDB and Folk CRM

Treat Folk CRM 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 People, Companies, Groups, Custom fields from Folk CRM into Attached databases, Database files, Schemas, Tables in DuckDB with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Folk CRM 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 enriched contact data from a data warehouse into folk custom fields.
  • Mirror folk groups into a reporting database to track pipeline and outreach coverage.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • Push aggregates computed in DuckDB out to a CRM or business tools so analysis results reach operational systems.
