About

Viz.ai is a healthcare AI company founded in 2016 that applies computer vision and AI to medical imaging to detect critical conditions and automate care coordination workflows. The platform analyzes CT scans and other medical images in real time, identifying conditions including large vessel occlusion stroke, pulmonary embolism, aortic dissection, and incidental findings, then automatically notifying and coordinating the relevant specialists through a HIPAA-compliant communication platform. Viz.ai has received FDA clearance for over 20 AI algorithms and is deployed at over 1,400 hospital sites across the United States. The company raised over $250M at a $1.2B valuation and has demonstrated that AI-powered care coordination reduces door-to-treatment time for stroke by tens of minutes, which translates directly into better patient outcomes. The platform creates a connected care team workflow where radiologists, neurologists, ER physicians, and interventionalists are automatically looped in when a critical finding is detected. Viz.ai serves as essential care coordination infrastructure for time-sensitive conditions where rapid multi-specialty response is critical to preventing death or disability.
