Sarus is a French privacy-focused data analytics company founded in 2020 and headquartered in Paris. The company develops technology that enables organizations to analyze and extract value from sensitive data while maintaining privacy and regulatory compliance. Sarus builds tools centered around privacy-preserving data analytics and AI, applying techniques such as differential privacy to allow data teams to run queries and train machine learning models on sensitive datasets without exposing underlying personal information. This approach is designed to help organizations meet data protection requirements while still enabling internal analytics and external data collaboration. The platform is positioned for use in regulated industries where data sensitivity is a primary concern, including finance and healthcare. Sarus targets both public and private sector organizations that need to derive analytical insights from data that would otherwise be restricted due to privacy obligations. The company was founded by Maxime, Nicolas, and Vincent — three co-founders who previously built and sold AlephD, an ad-tech startup acquired by Verizon Media in 2016. Sarus has received investment from Y Combinator and European backers, and has also been funded through the EU's EIC Accelerator program. Sarus maintains an open-source presence on GitHub and publishes technical content through a blog and Medium. Their product suite includes data discovery and access controls layered with privacy-enhancing technologies, enabling data scientists and analysts to work with production data in a governed, compliant manner.
