“Employees must wash their hands before returning to work”

But how does one know if they do? Truth is nobody knows except the employees themselves. This, for decades, has been one of the biggest challenges for companies in the food and beverage industry. In the US alone, food incidents, of which bad hand hygiene is a main cause, cost food companies over $55 billion every year. solves that challenge.

We are a smart hygiene start-up that helps companies track workplace hand hygiene in real-time using artificial intelligence. Our state-of-the-art device enables them to achieve 100% hand hygiene compliance and reduce hand hygiene-related incidents by 97% at less than 10% the cost of alternative solutions.

What’s the technology? is the first company in the world that uses advanced computer vision technology and artificial intelligence to guide employees through their hand wash with gamification. The device collects and analyzes data in real time to provide managers with intelligent management dashboards with insights into the hand hygiene standards of their companies and the industry at large.

We are in the process of filing a suite of patents for this technology.

What’s next for your team?

We’re finishing our prototype for a pilot with some food companies in California. We keep the pilot small but companies which are interested in trying out our device can join a waitlist by emailing us at

After the demo day in May, we will kick off fundraising for a seed round right away. The money raised will be used primarily for recruiting new employees and manufacturing. We’re actively looking with talent in product management, UX/UI design, sales, and operations.
