Butterfly Network vs VUNO
A Seoul company listed on KOSDAQ, VUNO builds mostly image-reading tools. Its FDA decisions cover chest X-ray triage for pleural effusion and pneumothorax (K241439, November 2024) and brain MR volumetry (K231398, October 2023). The chest page says the product is integrated with PACS and names no PACS vendor. The site lists sales and general email addresses and no price.
On the Butterfly side, Advanced Technology software costs $1,500 one-time with five years of guaranteed access (currency not stated). The Gestational Age Tool, cleared in March 2026, needs an iQ+ or iQ3 plus an Advanced membership.
One sells ultrasound hardware and the other sells software for radiographs, MR and fundus photographs. An OB or primary care clinician scanning at the bedside is Butterfly's buyer. A radiology department with a chest X-ray worklist or a brain MR protocol is VUNO's.
