Pathos AI
Pathos AI is an AI-driven biotech company building what it describes as one of the largest multimodal foundation models in oncology. By combining millions of clinical, molecular, and imaging records with proprietary AI, Pathos aims to identify the right patients for a given therapy, design smarter adaptive clinical trials, and de-risk cancer drug development. Founded in 2020 by Eric Lefkofsky and Ryan Fukushima and led since 2025 by CEO Iker Huerga, the company raised a $365 million Series D that valued it at roughly $1.6 billion.

Iker Huerga is the CEO of Pathos AI, a New York- and Chicago-based biotech building what it calls the first true AI-enabled drug development platform for oncology. A data scientist by training with more than two decades at the intersection of machine learning and cancer research, he previously served as Chief Data Scientist for Oncology R&D at AstraZeneca and as an EVP at Tempus Labs, and founded three oncology companies with two successful exits. He took the helm at Pathos in May 2025, days before the company closed a $365 million Series D that valued it at roughly $1.6 billion, with a stated mission to get the right therapies to the right patients, sooner.
