Werner Eriksen is the CTO and Co-Founder of Working Group Two. Working Group Two built a mobile core network from the ground up to support product development and offers this mobile core network as a service to mobile operators. Their story began in 2013 with product development challenges in mobile cores, which led them to apply open source principles to build a mobile core network in the cloud by 2015. They are now working with customers to develop products using their network while still innovating.
