Census vs Fivetran

Census is a reverse ETL and data activation platform founded in San Francisco in 2018 and acquired by Fivetran in 2025. It syncs modeled data from cloud warehouses such as Snowflake, BigQuery, Databricks and Redshift into the business tools teams use every day, including Salesforce, HubSpot, Braze, Marketo and ad platforms, so that sales, marketing and support act on the same numbers as the data team.

Beyond plain syncs, Census offers Audience Hub, a visual segment builder for marketers, entity resolution to unify customer identities in the warehouse, observability with alerts and sync history, and tight dbt integration so models can be synced directly. More than 200 destinations are supported. Pricing now follows the Fivetran model: a free plan includes 3,500 monthly active rows for activations, while Standard, Enterprise and Business Critical plans are usage-based and billed on monthly active rows, so cost grows with the volume of data synced.

Census suits companies that already have a warehouse and a data team and want to activate that data without building custom pipelines. It is of little use without a warehouse, and since joining Fivetran its roadmap is increasingly tied to Fivetran's platform. Hightouch is the closest competitor and has expanded further into a composable CDP, while Segment and RudderStack combine event collection with activation.

Fivetran is a managed ELT service founded in 2012 in the United States and the most widely used tool for moving data into cloud warehouses without building pipelines. It provides hundreds of pre-built, vendor-maintained connectors that replicate data from SaaS applications, databases, files and event streams into Snowflake, BigQuery, Databricks, Redshift and data lakes.

Connectors handle authentication, incremental syncs, API changes and schema drift automatically, so new columns and tables appear in the destination without manual work. Database replication uses change data capture, including the HVR technology Fivetran acquired in 2021. Transformations run with dbt. In 2025 Fivetran added reverse ETL by acquiring Census, and its all-stock merger with dbt Labs, announced in October 2025, closed in June 2026. Pricing is usage-based on monthly active rows (MAR), with a free plan for low volumes and higher tiers adding faster syncs, private networking, HIPAA and other compliance options.

Fivetran fits lean data teams that value reliability and want to spend time on modeling rather than pipeline maintenance. The trade-off is cost: MAR pricing can rise sharply with high-churn tables and is hard to forecast, and you have less control than with code-based tools. Airbyte is the main open-source alternative with self-hosting, Stitch and Hevo are cheaper managed options for smaller volumes, and dlt suits engineers who want pipelines in Python.
