睦星科技
Muxing Technology (睦星科技, also known as Kolmostar) is a Beijing-based startup specializing in low-power, high-precision GPS positioning algorithms and solutions for IoT devices, wearables, and vehicles . The company was co-founded by Tong Tao (童瑫), who serves as co-CEO and holds a PhD in electrical and computer engineering from Harvard . Its core technical invention came from Vincent Hua, an early participant in Stanford's LIGO gravitational-wave detector signal-processing project, whose expertise in signal processing and noise cancellation shaped the company's approach to GPS sensor design .
FreeS Fund (峰瑞资本) backed Muxing from angel stage through its $10 million Series A in 2019, with founding partner Li Feng citing the firm as an example of the "algorithm plus chip" investment thesis the fund pursued early .
