Why teams connect Affinity and Citus

Treat Affinity like part of your database: its records live in Citus 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 Citus, where it can be queried and joined like everything else.

Stacksync mirrors Organizations, Opportunities, Field Values, Notes from Affinity into Views, Sequences, Distributed tables, Reference tables in Citus with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Affinity 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

  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • Sync notes and reminders into project or task systems used outside the deal team.
  • Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.

Trigger workflows from CRM changes

Field and stage updates in Affinity arrive as row changes in Citus, ready to drive jobs and notifications.

Query the CRM like a database

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

Product events onto CRM records

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

What you can sync between Affinity and Citus

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 Citus objects
Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. Sequences Key generators that matter when external writes must not collide with application inserts.
Organizations Company records matched to accounts in other systems by domain. Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets.
Opportunities Deal records tracked on lists and synced with pipeline reporting. Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables.
Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables.
Notes Meeting and call notes synced for record-keeping in other systems. Schemas Standard Postgres namespaces used to scope what a sync user can read and write.
Interactions Automatically captured emails and meetings, read for activity reporting. Views Curated projections over distributed data, often used as read-only sync sources.
