Stop syncing bad data

It’s time for an integration revolution – no more fragile python scripts or manual CSV uploads. Stop losing valuable data using point to point integrations.

Old Way

Point-to-point or event driven solutions like python scripts, iPaaS tools and CDPs are easy to get started with, but quickly become unmanageable.

It’s the perfect recipe to get bad data everywhere.

New way: Reverse ETL

Reverse ETL makes your data warehouse the source of truth for all your operations. Break down silos and combine data across the organization.

A clean way to get good data everywhere.

Sync with confidence with DeltaSync

You no longer have to worry about API rate limits. Our DeltaSync engine only syncs what’s changed. Whether that’s a new field, new record, or a change in an existing field, we’ll intelligently diff it and sync it over.

"Since Census only syncs what needs to be synced - changes, additions, and deletions - the volume of data sent back to Braze is relatively low"
Cuong Duong, Data Analyst

Empower your business teams

With our simple UI, visual field mapper, and segment builder you can sync data to your destination apps with no APIs or code. You can also leverage the power of SQL to build operational models like lead scores.
