While practicing as a neurosurgeon in the U.K., Chris Mansi saw firsthand how surgery could go well, yet a patient would still die because too much time had passed before getting to the operating room.

In 2016, while working on an M.B.A. at Stanford Business School, Mansi met David Golan, an Israeli machine-learning postdoc who’d recently been discharged from the hospital after a suspected stroke. The two bonded over the lack of data to drive better medical decisions and pitched their idea to improve stroke care in a class run by former Google CEO Eric Schmidt, who offered seed funding through his firm Innovation Endeavors.

The San Francisco-based company’s software cross-references CT images of a patient’s brain with its database of scans to find early signs of large vessel occlusion strokes. This year, Viz.ai made the Forbes Next-Billion Dollar Startups List, being ranked among 25 companies most likely to become future unicorns.
