Key takeaways

  • Understanding comparing the 9 best reverse etl tools for 2025 is key for modern data teams.
  • A structured approach helps organizations scale their data governance efforts.

Quick Answer: What are reverse ETL tools used for?

Reverse ETL tools move transformed data from data warehouses (Snowflake, BigQuery, Redshift) back to operational systems like CRMs, marketing platforms, and support tools. They enable data activation by syncing customer insights, ML predictions, and analytics results to business applications. Top tools include Census, Hightouch, Polytomic, Grouparoo, and Rudderstack, each offering unique connectors, transformation capabilities, and sync frequencies.

Key tool capabilities:

  • Data warehouse sources — connect to Snowflake, BigQuery, Redshift, Databricks
  • Destination connectors — sync to Salesforce, HubSpot, Marketo, and 100+ apps
  • Transformation logic — apply business rules and mappings before syncing
  • Sync scheduling — real-time, hourly, or batch synchronization options
  • Data activation — operationalize warehouse data for business teams

This capability is particularly beneficial for marketing teams, enabling them to personalize campaigns effectively.

With a staggering 68% of enterprise data left untapped, leveraging reverse ETL tools is critical for driving data-driven decisions.

Reverse ETL tools act as a bridge between your data warehouse and any business intelligence tools of your choice. They help you automatically retrieve real-time data from data repositories and feed them into BI tools. In this blog, we will explore the top nine Reverse ETL tools for you to consider in 2025.

These tools are crucial because 68% of enterprise data remains unleveraged, and only 32% is used, according to a SeaGate report (with research and analysis by IDC). A key reason is that warehouse data doesn’t reach business applications timely.

That’s where reverse ETL tools can help.

Census

Overview


Census enables operational analytics for sales, marketing, data, product, and customer success teams.

Boris Jabes, Brad Buda, Sean Lynch, and Anton Vaynshtok founded Sutro Labs Inc. — the company behind Census — in 2018. The company’s backed by Silicon Valley investors such as Sequoia Capital, Andreessen Horowitz, SV Angel, Box Group, and Insight Partners. Tiger Global led the latest funding round to raise $60 million.

Census’ customers include Canva, Crossbeam, Figma, dbt Labs, Loom, MasterClass, Mixpanel, and Notion. Here’s a case study to help you understand what Census does.

Case study: How did Docker use Census to drive product-led growth for over 10M users?


When Docker sold a portion of its business to focus on products for app developers, they faced two problems:

  1. The data set didn’t represent their current audience
  2. The custom data pipelines didn’t support new use cases

Docker had to build new data integrations but didn’t wish to divert engineering resources from the core business, as the company was a small startup.

Moreover, they still had a large customer base of 10 million, and numerous activities to engage with this base, but tapping into that data was a challenge.

So, Docker used Snowflake to centralize all data and then chose Census to feed that data back to business teams such as ”marketing and developer relations”. As a result, these teams now have access to the data they want, when they want it, which improved personalization in their campaigns and uncovered new sales opportunities.

Case study: How did DocOn eliminate manual data integration and reporting with Hevo?


DocOn is an EMR (Electronic Medical Records) platform in India. Initially, when the data volume was low, Docon’s data team used Google Sheets for data aggregation and reporting.

As the volume grew, the company needed a central data repository and an integration tool to automate data pipeline setup and maintenance.

So, DocOn used Redshift as their data warehouse and used Hevo to simplify their engineering requirements and feed warehouse data to the relevant systems, eliminating manual data integration, aggregation, and reporting.

How organizations making the most out of their data using Atlan

The recently published Forrester Wave report compared all the major enterprise data catalogs and positioned Atlan as the market leader ahead of all others. The comparison was based on 24 different aspects of cataloging, broadly across the following three criteria:

  1. Automatic cataloging of the entire technology, data, and AI ecosystem
  2. Enabling the data ecosystem AI and automation first
  3. Prioritizing data democratization and self-service

These criteria made Atlan the ideal choice for a major audio content platform, where the data ecosystem was centered around Snowflake. The platform sought a “one-stop shop for governance and discovery,” and Atlan played a crucial role in ensuring their data was “understandable, reliable, high-quality, and discoverable.”

For another organization, Aliaxis, which also uses Snowflake as their core data platform, Atlan served as “a bridge” between various tools and technologies across the data ecosystem. With its organization-wide business glossary, Atlan became the go-to platform for finding, accessing, and using data. It also significantly reduced the time spent by data engineers and analysts on pipeline debugging and troubleshooting.

A key goal of Atlan is to help organizations maximize the use of their data for AI use cases. As generative AI capabilities have advanced in recent years, organizations can now do more with both structured and unstructured data—provided it is discoverable and trustworthy, or in other words, AI-ready.
