PathAI

PathAI develops AI tools for pathology that analyse tissue slide images to help pathologists diagnose disease and measure biomarkers. Pharmaceutical companies use it in clinical trials, and labs use its AISight platform to manage digital pathology workflows.

AISight stores and displays whole-slide images, routes cases to pathologists and runs AI models that quantify features such as tumour cells or tissue patterns. In drug development, PathAI's algorithms provide consistent measurements across trial samples that would be slow to score by hand.

PathAI is based in Boston and works with labs and pharmaceutical partners through custom agreements. Several of its algorithms are used in clinical trials run by large drug makers, and it also operates its own accredited laboratory for research and testing services.
