Census takes what the analytics team does out of static dashboards and into tools that the rest of the company uses, allowing us to actually deliver on the promise of being “data driven”.

Matt Nicosia
Director of Growth

I used to develop reverse ETL systems with Python and Airflow for destinations like Eloqua, Mixpanel, Braze, Intercom, and Salesforce. Every destination requires different data types, formats, rate limits, and API requests. Census saves me from maintaining my custom code, so I can spend more time to optimize the system itself.

“My favorite tool in our martech stack!!”

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.

Example of syncing data point to point

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.

A reverse ETL tool is the solution that combines data across the organization

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.

I’m actually nervous to walk the sales team through how well Census and Salesforce play together, because I know that’s going to be like turning on the fire hose.

Why leading companies trust Census for Reverse ETL

Sync with confidence with incremental diffing

You no longer have to worry about API rate limits because we only sync what’s changed. Whether it'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.
