Viz.ai develops automated analyses of brain scans that can be quickly transmitted to doctors and help the treatment of strokes. Viz.ai’s software connects to CT scanners and alerts stroke specialists that a suspected large vessel occlusion (LVO) stroke has been identified, sending the radiological images directly to their smartphone.

In a statement, the company said it will use the funding to extend product portfolio beyond strokes.

Based in San Francisco and Tel Aviv, Viz.ai was founded in 2016 by Israeli machine learning specialist David Golan, together with Chris Mansi, a neurosurgeon, and Manoj Ramachandran, an orthopedic surgeon. In April, the U.S. Food and Drug Administration (FDA) cleared Viz.ai’s Viz CTP technology that uses image processing software to view and analyze CT scans. This is the second FDA approval for Viz.ai, after its computer-aided triage and notification platform to identify LVO strokes was cleared in February. In January, the company received the European CE Mark for the technology.

Viz.ai has previously raised $7.5 million from former Google CEO Eric Schmidt's venture capital firm, Innovation Endeavors and Danhua Capital.
