Craig Kohler is the founder and CEO of ONVI, a Chicago-area oral health technology company building what he calls the operating system for oral health. A dentist for four decades on Chicago's North Shore, he spent 20-plus years recording procedures through surgical microscopes and noticed a pattern: patients who could actually see inside their own mouths started taking better care of their teeth. He turned that observation into a product line - the video-enabled Prophix brush, the LED-lit MOTSY Light manual brush, and the HIPAA-compliant ONView platform - backed by 39 patents and a $25 million Series A raised in August 2025.
ONVI is a Chicago-based oral health technology company building what it calls an operating system for dental care. Founded by dentist Dr. Craig S. Kohler, the company pairs camera-equipped brushes - led by the Prophix video toothbrush - with a HIPAA-compliant software platform, ONView, that links what people see in their own mouths to their dentists. In August 2025 ONVI launched a $25 million Series A to commercialize a six-product hardware-and-software system aimed at closing the visibility gap between dental visits.
