New media agency Icon Medialab UK has parted company with its managing director, David King, who has left "to take on new challenges".
King grew Icon Medialab UK from 4 people and no clients to 70 people and an extensive client list.
He is replaced by Erik Wickström, one of the four founders of Swedish based Icon Medialab, who will lead Icon UK into the next stage of expansion.
Wickström said: "We are increasing our range of services to meet the growing demands of the digital age. The changes planned for Icon Medialab will enable even greater creativity, innovation and quality of service."
