Our four co founders, Bao Xinjin, Gong Guolong, Bao Xinjian, and Liu Xuzhi, all come from STEM backgrounds and have similar work experiences. Among them, Bao Xinjin and Gong Guolong have worked together for many years, and because they share the same work philosophy, they sympathize with each other. So in 2017, they established Tashi IoT Company in Hangzhou and launched the IoT brand - Tashi, followed by the sensor brand - Yishi.
