About Us

Under the PRIZM group there have always been a group of technology people who develops and supports the technical operations. However, there are a few of us who are more tech savvy that think we could do a lot more and focus on offering data, digital and AI technology solutions to our customers. As a result, DataTech Global is born as a new business unit under the PRIZM group. We specialise in utilizing data to create Artificial Intelligence augmented digital products and services. We offer our clients the one-stop solutions to leverage Data, Digital and AI technology into their business to magnify their potential.

Today we have two offices. One located in HK where we all started and another at the beautiful New Zealand down at the Southern Hemisphere.
