Momentum Worldwide has promoted Kev Exley to UK executive creative director, replacing Mike Kettles, who moves into a growth consultancy role within the agency.
Exley, who joined Momentum in 2017 as creative director before becoming creative partner, will lead the UK creative team. His most recent work includes a collaboration with photographer Rankin and British rapper Stefflon Don to promote Samsung's latest phone launch.
Trak Ellis-Hill, meanwhile, has joined the IPG network in the newly created position of UK creative managing partner from her role of six years as ECD at You & Mr Jones-owned Mofilm. Ellis-Hill will drive content solutions across the experiential agency and report to Exley.
Kettles joined Momentum as ECD in 2016, having previously worked as director of creative and strategy for A Little Bird.
The agency has also promoted Sarah Poole from head of art to creative director.
Luke D'Arcy, UK president, Momentum Worldwide, said: "This year holds so much potential for physical and digital experiences to combine, and both Kev and Trak are experts in bringing these blended worlds to life. I am excited to see an increase in the diversity and creativity of our offer under the leadership of this formidable duo."
