Achiever Big Data provides location analytics solutions for smart city development ranging from retail, food and beverage, Industry 4.0, healthcare, transport to smart community. Inspired by experiments of particle movement in Daya Bay Nuclear plant, 2 of our PhD co-founders invented an indoor positioning algorithm for human and assets with improved accuracy of 1.5 meters. We also aim to develop our “world map” - a city-scale big analytics solution to analyse behaviour of every citizen. By placing our sensors to different spots and knowing their presence in different time, we can understand what the society needs and develop a smarter city.
