Viz.ai, Inc.

The San Francisco AI company that taught the industry to sell clinical AI as a care-coordination workflow rather than a detection score. Its stroke software received the FDA De Novo authorization that created the computer-aided triage category (2018) and the first Medicare New Technology Add-on Payment for AI (FY2021). It then spread across ~2,000 US hospitals and into cardiology, pulmonology and oncology, and built a second business selling patient-identification services to drug and device companies.
