About Proscia

Pathology is at the center of medicine and is undergoing a profound transformation as the final frontier of digitization in healthcare. We started Proscia to accelerate pathology’s transition from microscope to images, and to use that data to change the way we think about cancer. We can’t change medicine alone. That’s why we’re looking for curious thinkers. Big dreamers. Developers, evangelists, pathologists, and scientists. Exceptional talent to help us use great power for good and advance humankind.

At Proscia, we push the limits of medicine and technology, solving problems the world has never solved before. We build software used by thousands of scientists and pathologists, who work on the front lines of fighting big enemies, like cancer, for patients around the globe. To accelerate our vision, Proscia has raised capital from great investors like Highline Capital Management, Emerald Development Managers, Triangle Peak Partners, Alpha Intelligence Capital, Scale Venture Partners, Hitachi Ventures, Flybridge, and more.
