Chief executive officer

Havas London

Xavier Rees is CEO of creative agency Havas London and customer engagement agency Havas helia.

He joined Havas from adam&eveDDB in 2016, where, as Group Managing Director, he helped lead the agency through its most successful period, including winning Cannes’ coveted global agency of the year accolade.

Rees has also worked for BBH, Wunderman, Archibald Ingall Stretton and RMG/JWT, running some of London’s largest accounts including Sony, Volkswagen, Audi, and O2.

In 2018, he oversaw Havas London’s certification as a B Corporation – a business that balances purpose and profit, and one legally required to consider the impact of its decisions on employees, customers, suppliers, its community and the environment. He also serves as an ambassador for B Corp UK.

He is a devout Crystal Palace fan – one of many afflictions – and obsessively collects music, books and deeply average marathon times.
