Butterfly Network vs Viz.ai
A bedside ultrasound program and a stroke network are different buyers. Butterfly Network lists a probe and individual memberships, and Viz.ai is sold to health systems after a demo request.
An emergency physician or a small ultrasound program buying a handheld whole-body probe pays $3,899 for the iQ3 (currency not stated), which carries a 3-year warranty. The Advanced Technology membership at $420 per year (currency not stated) adds the Auto Bladder Volume and Auto B-Line Counter tools.
Viz.ai pushes suspected large-vessel occlusions, hemorrhages, aneurysms and pulmonary emboli to care-team phones. The vendor's July 2026 release claims 2,000 hospitals and 13 FDA clearances, while openFDA shows 10 510(k)s and 2 De Novos. A 2025 meta-analysis of 12 studies and 15,595 patients found shorter door-to-groin times and no significant difference in clinical outcomes.
