Why teams connect ClickHouse and Freshworks CRM

Sync Freshworks 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. Accounts, Deals, Tasks, Appointments from Freshworks CRM land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Freshworks CRM. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Push scored leads from a data platform into Freshworks CRM and route them by lifecycle stage.
  • Two-way sync accounts and deals with an ERP so quotes and invoices reference the same customer records.
  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in ClickHouse appear as fields in Freshworks CRM, where the people working accounts actually see them.

A single customer view

Join Freshworks 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.
