AT Nakanishi
AT Nakanishi (Atsushi Nakanishi) is the founder and CEO of Triple W, the company behind DFree, the world's first personal wearable ultrasound sensor that predicts toilet timing. He launched the company in 2015 with high school and college friends, took it from Tokyo to Berkeley, and steered it to a Best of CES award and Series D funding. A self-described non-engineer who built a hardware company from zero, Nakanishi blends business pragmatism with a stubborn focus on solving an unglamorous, very human problem.
Triple W USA (DFree)
Triple W USA makes DFree, the first wearable ultrasound sensor that predicts when you need to use the bathroom. The matchbox-sized device sits on the lower abdomen, tracks bladder fullness in real time, and sends an alert to a phone or tablet before it is too late. Founded by Atsushi Nakanishi in 2015 and headquartered in San Diego, the company sells to individuals, caregivers, and senior care facilities under the banner of dignity and independent living - 'diaper-free.'
