Gareth Williams is a startup investor in Bristol. Gareth hounds the YellowDog kennel, spearheading the vision to build a world where people do more, create more, discover more; unleashed from limited computing power. 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, ExperianQAS, 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 and talking to anyone (usually together).
