We’ve trained a multimodal AI model to turn routine pathology slides into spatial proteomics, with the potential to reduce time and cost while expanding access to cancer care.







Today, we announce a strategic research collaboration between Ataraxis AI and MEDSIR (@wearemedsir), a global leader in oncology research. The partnership will evaluate the Ataraxis Breast platform in several international randomized controlled trials. Together, we aim to generate robust clinical evidence on the role of artificial intelligence in predicting outcomes and treatment effects in early-stage and metastatic breast cancer. The analyses will especially focus on novel therapies investigated in MEDSIR's groundbreaking trials, including CDK4/6 inhibitors and antibody-drug conjugates (ADCs). This is one of many ongoing partnerships at Ataraxis working on developing a robust evidence base supporting the accuracy and utility of Ataraxis AI-native tools, and moving AI precision oncology closer to becoming the standard of care.

🏆 Ataraxis won 1st place at the Nebius AI Discovery Awards! Out of 250+ global contenders innovating at the intersection of AI and life sciences, our team was honored to receive the top prize in the biotech category — and a $100,000 award — at the @nebiusai AI Discovery 2025 ceremony today! This recognition as a frontrunner in AI-driven precision medicine is a meaningful milestone, especially as we shared the stage with so many trailblazing startups redefining the future of healthcare. Thank you for this recognition of our work, our Ataraxis Breast AI tests, and Ataraxis research that helps personalize treatment for cancer patients worldwide.



We’re proud to welcome Dr. Corey Speers as the new chair of the @UABHeersink Department of Radiation Oncology. His expertise will be a tremendous asset as we continue advancing cancer research, treatment, and education. Welcome, @cwspeers! Read more: bit.ly/438BEts



We are hiring for multiple engineering & research roles at Ataraxis AI! We recently raised a $20.4m Series A from top investors (AIX Ventures, Peter Thiel) and are quickly growing to help millions of cancer patients worldwide. Apply now at: jobs.ashbyhq.com/ataraxis-ai






Big day: Ataraxis raised a $20.4 million Series A from @aixventureshq, @peterthiel, and other top tier VC funds and angel investors, including OpenAI & DeepMind researchers. This funding round comes just a few months after we revealed Ataraxis Breast, the world's first AI-native platform to personalize treatment in breast cancer patients. We also launched Kestrel, our state-of-the-art foundation model for digital pathology. Our frontier AI lab is dedicated to developing and clinically deploying tools that personalize treatment for cancer patients. In October, an 8,000-patient clinical validation study confirmed that Ataraxis Breast accurately identifies high- and low-risk patients, significantly outperforming legacy diagnostic tests. Ataraxis Breast is just the first of many Ataraxis products, and with our Series A financing, we will accelerate their development and deployment to help cancer patients worldwide. Ataraxis is already back to building, and we’re looking for exceptional people to join us. If you're passionate about AI and medicine and want to be a part of the fastest-growing AI precision medicine company, consider joining our team: jobs.ashbyhq.com/ataraxis-ai We are sharing this milestone alongside an exclusive TechCrunch feature. A huge thank you to our employees, investors, patients, and physicians—this journey wouldn’t be possible without you. This is just the beginning.
