Launch HN: Sarus (YC W22) – Work on sensitive data with differential privacy

Hi HN! Maxime, Nicolas, and Vincent here, founders of Sarus ( https://www.sarus.tech ). Sarus is a privacy engineering software that lets data scientists work on data without the need to access it. It works like a proxy between the practitioner and the data. All queries and data processing jobs are executed on the original data with the privacy guarantees of differential privacy. When data is sensitive, getting access can be a huge pain. It means going through a long manual validation process that includes designing, and implementing an appropriate data anonymization. It takes weeks to months and some data utility may be lost to the masking requirements. Sarus makes all of it irrelevant by letting analysts work on data that is never accessed. Analysts only access outputs of their data jobs, and those can be protected with appropriate privacy measures. With past lives in healthtech, finance, and marketing, we’ve experienced first-hand that data governance has taken a huge part
