Personalized Cancer Treatment | Ataraxis AI Raises $20M

The Emerging Role of AI in Cancer Treatment Decisions

Artificial intelligence is rapidly gaining prominence within the field of cancer care, with the primary focus currently centered on the early detection of the disease. This emphasis is logical, considering the well-established correlation between earlier detection and improved patient outcomes.

However, a less frequently addressed, yet equally crucial question is whether aggressive treatments, such as chemotherapy, are always necessary upon diagnosis. Ataraxis AI is a company dedicated to addressing this very challenge.

Predicting Cancer Outcomes with AI

This New York-based startup is developing AI solutions to not only determine the presence of cancer but also to forecast a patient’s likely prognosis over a five to ten-year period.

If the probability of cancer recurrence is low, chemotherapy could potentially be avoided, resulting in significant cost savings and the elimination of its often debilitating side effects.

Launch of First Commercial Test and Funding

Ataraxis AI is preparing to introduce its initial commercial diagnostic test for breast cancer to oncologists across the United States in the coming months, as reported by co-founder Jan Witowski to TechCrunch.

To support this launch and facilitate expansion into other cancer types, the company has secured $20.4 million in Series A funding, exclusively announced to TechCrunch.

Investment Details

The funding round was spearheaded by AIX Ventures, with participation from Thiel Bio, Founders Fund, Floating Point, Bertelsmann, and existing investors Giant Ventures and Obvious Ventures. Ataraxis initially emerged from stealth mode last year after raising a $4 million seed round.

Founding Team and Technology

The company was co-founded by Witowski and Krzysztof Geras, an assistant professor at NYU’s medical school specializing in AI applications.

Ataraxis’ technology utilizes an AI model that analyzes information extracted from high-resolution images of cancer cells. This model has been trained on a vast dataset comprising hundreds of millions of images from thousands of patients, according to Witowski.

Recent studies indicate that Ataraxis’ technology demonstrates 30% greater accuracy compared to the current standard of care for breast cancer, as claimed by Ataraxis.

Future Goals and Vision

Looking ahead, Ataraxis has ambitious goals. The company aims to influence the treatment of at least half of all new cancer cases by the year 2030.

Furthermore, Ataraxis positions itself as a leading “frontier AI” company, focused on developing its own proprietary models, and benefits from the guidance of Yann LeCun, Meta’s chief AI scientist, as an advisor.

“We are striving to establish an AI frontier lab specifically for healthcare applications,” Witowski stated. “Many of the challenges in this domain necessitate truly innovative technologies.”

The Broader Landscape of AI in Cancer Care

The current surge in AI development has spurred significant investment in cancer care startups. For instance, Valar Labs raised $22 million in May 2024 to assist patients in navigating their treatment options.

Additionally, numerous companies are leveraging AI for drug discovery in the cancer field, such as Manas AI, which secured $24.6 million in January 2025 and was co-founded by Reid Hoffman, the co-founder of LinkedIn.

• Key Focus: Early cancer detection and personalized treatment.
• Technology: AI model analyzing high-resolution cancer cell images.
• Future Impact: Aiming to influence treatment for 50% of new cancer cases by 2030.
