Stroke Detection Startup Viz.ai Raises $50 Million

Stroke detection startup Viz.ai Inc. has announced it completed a $50 million series B funding round led by San Francisco-based Greenoaks Capital Partners LLC. Charles River Ventures (CRV), Threshold Ventures, GV (formerly Google Ventures), and Kleiner Perkins also participated in the round.

Viz.ai develops deep learning and artificial intelligence-powered technology that connects to a hospital CT scanner and can interpret brain scans. Viz.ai's software automatically alerts a doctor if a suspected large vessel occlusion (LVO) stroke has been identified, sending the radiological images directly to their smartphone. Founded in 2016, the company, which employs 80 people in San Francisco and Tel Aviv, has raised $28 million prior to this round.
