PathAI

PathAI is a healthcare AI company focused on computational pathology — using machine learning to analyze tissue samples and medical images for cancer diagnosis, drug development, and clinical trials. Founded in 2016 by Andy Beck and Aditya Khosla (MIT AI lab), the company has raised over $250 million.

PathAI's platform uses deep learning to analyze digitized pathology slides, identifying patterns in tissue architecture, cell morphology, and biomarker expression that inform cancer diagnosis and treatment decisions. The company's AI models assist pathologists in detecting cancers, grading tumors, and quantifying biomarkers with greater consistency and efficiency than manual review alone. PathAI's technology is used by pharmaceutical companies in clinical trials to identify patient populations most likely to respond to new therapies.

PathAI works with major pharmaceutical companies (Bristol-Myers Squibb, Novartis) and diagnostic laboratories to integrate AI into pathology workflows. The company represents one of the most commercially advanced applications of AI in healthcare diagnostics — a field where AI's ability to analyze vast amounts of visual data consistently and rapidly can directly improve patient outcomes.
