Exclusive: Not all cancer patients need chemo — Ataraxis AI raised $20M to personalize treatment

Mar 06, 2025 - techcrunch.com
Ataraxis AI, a New York-based startup, is leveraging artificial intelligence to enhance cancer care by predicting not only the presence of cancer but also the long-term outcomes for patients. The company aims to determine whether aggressive treatments like chemotherapy are necessary, potentially avoiding unnecessary side effects and costs. Ataraxis plans to launch its first commercial test for breast cancer in the U.S. soon, backed by a $20.4 million Series A funding round led by AIX Ventures and other investors. The startup's AI model, trained on extensive high-resolution cancer cell images, has demonstrated a 30% higher accuracy rate than current breast cancer care standards.

Co-founded by Jan Witowski and Krzysztof Geras, Ataraxis emerged from stealth with a $4 million seed round and has ambitious goals to impact half of new cancer cases by 2030. The company positions itself as a frontier AI lab for healthcare, with Meta’s chief AI scientist Yann LeCun as an adviser. The AI boom has spurred investment in cancer care startups, with companies like Valar Labs and Manas AI also raising significant funds. Charles Rollet, a senior reporter at TechCrunch, covers these developments and has a background in investigative reporting on the tech industry.
