Why teams connect BetterContact and ClickHouse

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

BetterContact 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 BetterContact — without exports, scripts, or schedulers.

Whatever BetterContact 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

  • 01 Backfill a warehouse of contacts with waterfall enrichment across 20+ data providers.
  • 02 Feed outbound sequencing tools with verified contact data before campaigns launch.
  • 03 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 04 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

Common sync patterns

Cross-tool reporting

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

Where BetterContact accepts updates: operational write-back

Segments, scores, or reference values computed in ClickHouse sync back onto records in BetterContact, 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 BetterContact or gets changed inside it.

What you can sync between BetterContact and ClickHouse

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.

BetterContact objects ClickHouse objects How this pairing syncs
Company Company data returned with each contact: name, domain, HQ location, industry, employee count. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Company is specific to BetterContact and Materialized views to ClickHouse — each maps to any object or custom field on the other side.
Lead Finder Search Prospect discovery by people and company filters, returning enriched lead profiles. Distributed tables Query-routing tables over cluster shards in self-managed deployments. Lead Finder Search is specific to BetterContact and Distributed tables to ClickHouse — each maps to any object or custom field on the other side.
Enrichment Request Batch or single submissions of up to 100 contacts per request for waterfall enrichment. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Enrichment Request is specific to BetterContact and Dictionaries to ClickHouse — each maps to any object or custom field on the other side.
Enriched Contact Verified work emails and mobile numbers with job title, LinkedIn profile, location, and skills. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Enriched Contact is specific to BetterContact and Tables (MergeTree family) to ClickHouse — each maps to any object or custom field on the other side.

How changes propagate between BetterContact and ClickHouse

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

BetterContact ClickHouse Sub-second propagation

DetectionBetterContact notifies Stacksync of record changes through webhook events. Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint.

DeliveryEach detected change is applied to ClickHouse as a row-level write, with types converted between the two schemas.

ClickHouse BetterContact Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

DeliveryBetterContact does not accept inbound record writes, so this direction carries requests rather than records: BetterContact's output flows back as field updates on the originating ClickHouse records.

Rate-limit considerations

  • BetterContact: Batches capped at 100 contacts per enrichment request.
