> Feno makes the Smartbrush, a U-shaped electric toothbrush with about 18,000 bristles that cleans every tooth at once in roughly 20 seconds, paired with a built-in scanner and an AI oral-health app. Direct-to-consumer, US-based.

Feno is a Los Angeles area (Culver City) oral-care hardware brand selling a connected "Smartbrush": a U-shaped mouthpiece that brushes all teeth simultaneously in about 20 seconds, replacing the standard two-minute routine. The brush has an embedded scanner that feeds the Feno app, which turns mouth images into personalized oral-health reports, trend tracking, and virtual coaching. The business model is hardware plus a recurring layer: a personalized TrueFit Mouthpiece, Feno Foam xylitol toothpaste, and a Feno Plus subscription for AI monitoring and dentist-connected insights.

The core customer is a time-pressed, health-conscious adult who wants a faster, more effective, lower-effort clean, with strong secondary pull from ADHD and neurodivergent users (the 20-second, low-effort routine is a documented draw) and parents buying for children. The brand positions hard around two ideas: the 20-second whole-mouth innovation and the link between oral health and overall systemic health. Sold direct on feno.co (Shopify) and on Amazon, with a "For Pros" motion aimed at dental professionals. Primary market is the United States, with meaningful demand in the UK, India, Canada, Australia, and Germany.
