James Bailey

dentsu UK Limited

James Bailey exemplifies transformational leadership in the media industry through his remarkable achievement of uniting two distinct agency cultures during a global pandemic. As CEO of iProspect UK, Bailey successfully merged over 600 employees across six locations, consolidating performance specialists iProspect and media agency, Vizeum, into a cohesive, award-winning organisation.

Under Bailey's leadership, iProspect has achieved exceptional commercial success, delivering 17% growth in client income. The agency's momentum accelerated over the past 12 months, with major wins including Sage, Hiscox, and eBay, as well as 2025 appointments by clients including Nothing Tech and PwC, among others.

Bailey's vision extends beyond financial metrics. He has championed regional talent development, proving that world-class agencies can thrive outside London with only 18% of employees based in the capital. This distributed model has become an industry blueprint for sustainable, inclusive growth.

The agency's creative transformation is equally impressive, achieving four UK Effie Awards, including the Grand Prix for IKEA. Bailey's leadership demonstrates that modern agency success comes from recognising talent everywhere and having the vision to connect it effectively.
