I'm fortunate to have worked across verticals in varying capacities throughout my career, and that experience has proven invaluable," says Appleby. "I'm eager to dig into my new role and lead our talented teams in delivering innovative and impactful media solutions for our clients."

As the newly appointed UK Managing Director, James Appleby will play a pivotal role in shaping the agency's strategic vision, fostering innovation, and enhancing client relationships. Appleby's deep understanding of media trends, and his proven ability to navigate the evolving competitive landscape, positions him as the ideal partner to Europe CEO Matt Adams.

"James is an exceptional leader for our people and clients – everyone wants to work for and with him," said Matt Adams, Assembly Europe CEO. "I'm excited to see how he can push us deeper into the UK market, driving transformation for brands and talent."
