Gareth Williams

Founder & CEO

Following an MEng in Information Systems Engineering from the University of Durham, Gareth cut his canines working in software and telecoms at companies including Orange, Experian QAS, FREEDOM4 and Arieso, where he was part of the Management Team that completed the successful sale of the company to JDSU in March 2013 for $85m.

One day he had a brilliant idea for using spare mobile capacity which, following a chat with someone in the animation department at the University of the West of England, gave birth to what is now YellowDog. When not coming up with brilliant ideas, he is a dad, a keen cyclist, an ardent reader, a Samaritans Listening Volunteer. He also likes ale.
