"I have great admiration for, and shared in Aktiv Digital’s success, and I look forward to a great working relationship in the future," he said. "Nevertheless, the time is right to explore new ways of embedding world-class interactive skills within an ever broadening cross-section of our industry."
Fawbert, who will continue to run UK-based Clockwork Consultancy, was previously vice-president for CBS Outdoor in China and head of sales for Yahoo! UK.
At Aktiv, he reported to group CEO Alex Khan, who said Fawbert’s amicable departure was a “sad loss” but allows the company to develop its digital strategy with new talent.
Khan has not released details of Fawbert’s replacement.
