Cleerly vs Viz.ai
Viz.ai holds two De Novo authorizations, ContaCT for LVO triage on CTA (granted February 2018) and Viz HCM (August 2023), plus ten 510(k)s. Its Trust Center lists SOC 2 Type II and ISO 27001, and a July 2026 release claims 2,000 hospitals. In stroke, a 2025 meta-analysis of 12 studies and 15,595 patients found shorter door-to-groin and door-in-door-out times and no significant difference in clinical outcomes.
Viz.ai sends mobile alerts to the care team and coordinates transfers for health systems running stroke, PE and aortic pathways across hospitals. Cleerly's workflow ends in a PowerScribe report, which suits a program that wants quantified plaque in the coronary CTA read and serial scans for progression or regression. Viz's cardiac tools target HCM, ACS and cardiac amyloidosis, so the two target different clinical questions. Cleerly's press materials say five of seven Medicare Administrative Contractors have finalized coverage policies.
