Why teams connect ClickHouse and Streak CRM

Sync Streak 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. Tasks, Email threads, Custom fields, Pipelines from Streak CRM land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Streak CRM. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Hand off closed-won boxes to billing or fulfillment systems and sync status back into the pipeline
  • Keep contacts aligned between Streak and email marketing or enrichment tools
  • 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 Streak CRM 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 Streak CRM, where the people working accounts actually see them.

What you can sync between ClickHouse and Streak CRM

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.

Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Organizations Company records associated with contacts and boxes.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Tasks To-dos attached to boxes for follow-up tracking.
Databases Namespaces that group tables and scope permissions for sync users. Email threads Gmail threads linked to boxes, since the CRM lives inside the inbox.
Views Saved queries used as curated, read-only sync sources. Custom fields Per-pipeline field definitions that determine what data a box can hold.
