Why teams connect ClickHouse and Kommo

Sync Kommo 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. Chats, Leads, Contacts, Companies from Kommo land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Kommo. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Push web form and product signups into Kommo pipelines as they are submitted so messenger-based follow-up starts quickly
  • Keep customer records consistent between Kommo and invoicing or ERP systems
  • Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.

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 Kommo are queryable in ClickHouse moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

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