About ZeroBrush
ZeroBrush Inc. operates within the oral wellness sector, positioning itself as a provider of advanced dental health products. Founded in 2014 by Dr. Nidhi Pai, a dentist, and Akash Pai, who serves as Chief Product and Operating Officer, the company was born out of Dr. Pai's frustration with patients' improper brushing techniques that lead to gum damage. Her professional background directly informed the core concept of the company. Akash Pai brings extensive product leadership experience from roles at Microsoft, Yahoo!, and Intuit, complementing the clinical expertise of the founding team.
The company's flagship product is a fully automated, hands-free oral cleaning device that utilizes a custom-fit mouthpiece. This mouthpiece is created from a 3D scan of an individual's teeth, enabling it to clean all tooth surfaces simultaneously and more consistently than manual or electric toothbrushes. Clinical results cited by the company indicate their device removes more plaque in 30 seconds than a manual toothbrush does in two minutes and is five times more effective on hard-to-reach inner tooth surfaces. The business targets consumers seeking improved oral hygiene, particularly those with gum health issues from aggressive brushing or individuals with dexterity challenges. The business model involves the initial device purchase and recurring revenue from the sale of replacement mouthpieces, which are recommended to be replaced every three months.
Headquartered in San Diego, California, ZeroBrush has secured $11.8 million in funding and is noted as being in the revenue-generating stage. The team includes experts in dental engineering, 3D printing, and consumer products, with key personnel having prior experience at companies like Sonicare, Oral-B, and Procter & Gamble. The company's strategy has involved targeting specific high-value consumer groups initially, with plans to expand to the broader population. It has also secured a partnership with an undisclosed major CPG company to aid in bringing its products to a wider market.
