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.
