The pair will join the agency later this year, and will form part of a new executive team alongside Robert Harwood-Matthews, the TBWA\UK president, and Mark Hunter, the executive creative director of TBWA’s London office.
Al-Zaidy replaces Tom Morton, who left in July to join Publicis as its chief strategy officer. De Groose is effectively a replacement for Matt Shepherd-Smith, who quit as TBWA\London’s chief executive in December last year.
Saint will not directly replace Al-Zaidy. De Groose began his advertising career as a media strategist at Michaelides & Bednash. He founded the digital agency Deconstruct in 2001 and it was sold to Isobar in 2004.
