Two-way sync
Changes in ClickHouse or Twenty CRM instantly reflect in both systems. No stale data, no manual imports.
Keep ClickHouse and Twenty CRM in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.
Stacksync does both with one connection. Attachments, Workspace Members, People, Companies from Twenty CRM land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Twenty CRM. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.
Deduplication and normalization done in ClickHouse can be written back, so warehouse-side cleanup actually fixes the CRM.
Accounts, contacts, and activity from Twenty CRM are queryable in ClickHouse moments after they change, so dashboards stop lagging the reality they describe.
Lead scores, churn risk, or usage segments computed in ClickHouse appear as fields in Twenty CRM, where the people working accounts actually see them.
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.
| ClickHouse objects | Twenty CRM objects | |
|---|---|---|
| Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. | Notes Free-form notes attached to records, useful for mirroring activity from other tools. | |
| Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. | Custom Objects User-defined objects created in Twenty's data model settings, addressable through the same APIs as standard objects. | |
| Databases Namespaces that group tables and scope permissions for sync users. | Attachments Files linked to records. | |
| Views Saved queries used as curated, read-only sync sources. | Workspace Members User accounts used for record ownership and assignment mapping. | |
| Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. | People Individual contact records with emails, phones, and company links; a core target for contact syncs. | |
| Distributed tables Query-routing tables over cluster shards in self-managed deployments. | Companies Account-level records that group people and opportunities. |

On Twenty CRM: Webhooks on record create, update, and delete events, or polling on record update timestamps. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
