Donovan was creative planner at pd3 for two years. He previously worked at Havas Sports & Entertainment, working with EDF Energy and its Olympic sponsorship and Orange and its European sponsorship programme. He also helped the agency win the global Yahoo World Cup promotion brief.
In addition, he has held roles at AMV BBDO and Ogilvy & Mather.
Jamie Wynne-Morgan, MD of M&C Saatchi Sport & Entertainment, said: "Stuart has extensive traditional brand account and sponsorship planning experience but his more recent role as a creative planner in the world of sport and entertainment made him a perfect fit for us as we continue to expand our strategy offer."
