Why teams connect ClickHouse and Veeva CRM

Sync Veeva CRM into ClickHouse continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

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. Key Messages and CLM Content, Territories and Alignments, Events, Approved Email Activity from Veeva CRM land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Veeva CRM. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Mirror medical inquiries into a medical information system for fulfillment and audit.
  • Sync HCP and HCO accounts between Veeva CRM and a customer master or MDM system to keep the customer master aligned.
  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

A single customer view

Join Veeva CRM's relationship data with billing, product, and support data in ClickHouse to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in ClickHouse can be written back, so warehouse-side cleanup actually fixes the CRM.

CRM analytics on live data

Accounts, contacts, and activity from Veeva CRM are queryable in ClickHouse moments after they change, so dashboards stop lagging the reality they describe.
