Hightouch (reverse ETL)
Hightouch is a reverse-ETL and data-activation platform that syncs modeled data from a warehouse into operational and marketing tools, and supports audience building on top of warehouse data (a 'composable CDP' pattern). Like other reverse-ETL tools it moves data out of the warehouse, keeping the warehouse as the source of truth for definitions.
What this means
Hightouch reads modeled warehouse tables and syncs selected fields into destinations — CRMs, ad and marketing platforms, support tools — on a schedule. It also offers audience-building on warehouse data, letting teams define segments without copying data into a separate CDP store.
This 'composable CDP' framing keeps customer data and definitions in the warehouse, with activation layered on top.
What to weigh
Like Census, Hightouch is reverse ETL — the opposite direction from ingestion. It assumes the warehouse holds your modeled source of truth. Its audience features overlap with traditional CDPs but keep storage in the warehouse rather than a vendor store.
- Syncs modeled warehouse data into business tools
- Audience building on warehouse data (composable CDP)
- Warehouse remains the source of truth
Where it fits
It sits after modeling, at the activation end of the stack. Compare it with packaged CDPs by where customer data lives — in your warehouse versus a vendor's store — and by sync coverage for your destinations.
How it appears in analytics and logs
A wrong downstream audience usually reflects the warehouse model or the audience/sync definition, not the destination tool — Hightouch syncs what the warehouse produces.
Diagnostic use case
Use Hightouch to activate warehouse-modeled data and audiences in business tools, often as part of a composable, warehouse-centered CDP approach.

Common mistakes
- Confusing reverse ETL with warehouse ingestion.
- Treating warehouse audiences as identical to a packaged CDP's store.
- Activating personal data without reviewing consent and routing.
Privacy and accuracy notes
Hightouch moves warehouse data, possibly personal, into third-party tools; routing, consent, and region are your responsibility. This is factual, not legal advice.

- Census (reverse ETL)
Census is a reverse-ETL (data activation) tool: it takes modeled data from your warehouse and syncs it into operational tools — CRMs, ad platforms, support and marketing apps — so teams can act on warehouse-defined audiences and metrics. It runs in the opposite direction to ingestion tools, which load data into the warehouse rather than out of it.
- Reverse ETL
Reverse ETL is the practice of taking modeled data from your data warehouse and syncing it back into operational tools — CRMs, ad platforms, marketing tools, support systems. Where ETL loads data into the warehouse, reverse ETL pushes warehouse-computed audiences and attributes out for activation, making the warehouse the source of truth even for operational use.
- Customer data platform (CDP)
A customer data platform (CDP) is software that collects customer data from many sources, unifies it into persistent profiles, and makes that unified data available to other systems for analysis and activation. The defining traits are unification (one profile per customer) and accessibility to downstream tools — not reporting, which is what analytics products do.
