• Co-founders include experts from Palantir and Google DeepMind.
• Funding will expand engineering and research teams significantly.

Valthos, a New York-based biosecurity startup, has launched with $30 million in funding. Publicly announced on October 24, 2025, Valthos aims to utilize artificial intelligence for real-time biological threat detection and the development of adaptive countermeasures. The funding round was co-led by the OpenAI Startup Fund, Lux Capital, and Founders Fund. The startup seeks to address risks associated with synthetic biology and emerging pathogens through advanced AI technologies.

Among its initiatives, Valthos is focused on building a technology stack that enables rapid identification of pathogens and prompt medical responses. This venture highlights the potential of AI in transforming biodefense strategies. Valthos is co-founded by Kathleen McMahon, Tess van Stekelenburg, and Victor Mao—each bringing significant expertise from their previous roles in life sciences and artificial intelligence.

Key Players and Their Contributions

Kathleen McMahon, formerly Head of Life Science at Palantir Technologies, plays a pivotal role as a co-founder of Valthos. Tess van Stekelenburg, with a background in computational neuroscience from the University of Oxford, and Victor Mao, a former research engineer at Google DeepMind, join her as co-founders. These individuals bring a wealth of knowledge and experience to the startup.

According to a statement by Jason Kwon, Chief Strategy Officer at OpenAI, the integration of AI into biodefense is crucial for maintaining technological leadership and supporting resilience. Each co-founder has made public statements emphasizing the importance of speed and innovation in facing biological threats: “In this new world, the only way forward is to be faster,” the Valthos team stated on X (formerly Twitter).

“Of all AI applications, biotechnology has the highest upside and most catastrophic downside.”
