Why teams connect ClickHouse and Lusha

Get the data locked inside Lusha into ClickHouse as live tables, and send results back where Lusha can use them, without writing a pipeline.

Lusha is a read-only source: Stacksync reads its data in real time and delivers it into ClickHouse, so ClickHouse always reflects the current state of Lusha — without exports, scripts, or schedulers.

Whatever Lusha is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Common use cases

  • Enrich new CRM leads with work emails and direct dials the moment they are created.
  • Backfill missing phone numbers on an existing contact list stored in a database or warehouse.
  • 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.

Cross-tool reporting

Combine Lusha's data with data from every other synced system to answer questions no single tool can.

Where Lusha accepts updates: operational write-back

Segments, scores, or reference values computed in ClickHouse sync back onto records in Lusha, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in ClickHouse preserves a queryable record even as data ages out of Lusha or gets changed inside it.

What you can sync between ClickHouse and Lusha

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 Lusha objects
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Email Addresses Work emails written into CRM contact fields during enrichment.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists.
Databases Namespaces that group tables and scope permissions for sync users. Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls.
Views Saved queries used as curated, read-only sync sources. Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Company Profiles Firmographic records (industry, size, location) appended to account or company rows.
