Ataraxis is an AI precision medicine company working at the intersection of multi-modal artificial intelligence and oncology. We develop and deploy AI-native tools to assist physicians in selecting the most optimal treatments for their patients.
Our mission is to change how cancer is treated and impact at least 50% of new cancer cases by 2030. We have already launched our first products, including the Ataraxis™ Breast platform for breast cancer, and help cancer patients get the most appropriate treatment every day. We work with the best academic institutions in the United States as well as small community clinics to deliver better care with frontier technology.
At Ataraxis, you will have a unique opportunity to shape not only the future of our company, but also the future of healthcare. You will join an exceptional team at the forefront of healthcare-focused AI research and deployment. As a frontier AI lab, we bring together leading AI researchers, medical doctors, and industry veterans. Our advisors include AI pioneers such as Yann LeCun and distinguished oncologists from top cancer research institutions, all united by the mission to redefine precision medicine.
Ataraxis has raised $24 million in funding, including a $20.4 million Series A in early 2025 led by top venture capital funds such as AIX Ventures (Hugging Face, Perplexity), Thiel Capital, Founders Fund (OpenAI, SpaceX, Palantir, Oscar Health), and Obvious Ventures (Recursion).
We are an company with a flat organizational structure, where every team member is empowered to actively contribute. Leadership roles are earned by those who demonstrate initiative and consistently deliver exceptional results. Strong work ethic and the ability to prioritize ruthlessly are essential.

What We Do
Ataraxis is an AI precision medicine company transforming cancer diagnostics and patient outcomes through the power of AI. We are addressing previously unsolvable problems in cancer prognosis and treatment selection through cutting-edge foundation models and multi-modal data. Our first clinically validated offering, Ataraxis Breast, is the world’s first AI-native prognostic/predictive test for breast cancer and provides greater accuracy than standard of care genomic assays.
