Ataraxis

Ataraxis AI is a precision-medicine company building clinical AI foundation models that make disease predictable, beginning with oncology. Founded in 2022 by Jan Witowski, MD, PhD, and Krzysztof Geras, PhD (both formerly of NYU), Ataraxis trains multi-modal AI on hundreds of millions of pathology images to assess disease aggressiveness and predict cancer recurrence, treatment response, and survival. Its first product, Ataraxis Breast, is an AI-native, clinically validated prognostic and predictive test suite for breast cancer (Recurrence Risk, Chemotherapy Benefit, and Neoadjuvant Response) delivering same-day results without exhausting physical tissue. The company is backed by Obvious Ventures, AIX Ventures, and Giant Ventures, and advised by Turing Award winner Yann LeCun. Ataraxis operates a clinician portal rather than a public developer API; this profile captures its public identity, legal, and security surface for the API Evangelist network.

Ataraxis is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Artificial Intelligence, Precision Medicine, and Oncology.

Ataraxis’ developer surface includes engineering blog, support, and 7 more developer resources.
