He is leaving the agency without a job to go to. He will not be replaced, with his responsibilities instead being split between TBWA\London’s president, Robert Harwood-Matthews, executive creative director, Dede Laurentino and chief strategy officer, Zaid Al-Zaidy.
De Groose joined TBWA\London is September 2010 from Isobar, where he held a similar position. He effectively replaced Matt Shepherd-Smith, who quit as TBWA\London’s chief executive the previous year.
De Groose began his advertising career as a media strategist at Michaelides & Bednash, before founding the digital agency Deconstruct in 2001, which was sold to Isobar in 2004.
Harwood-Matthews said: "We wish Andy all the best, he's helped us create a more future facing business and we respect his decision."
De Groose commented: "I have enjoyed my stint at TBWA greatly, but after careful consideration I have decided to pursue other ventures. I wish the whole team the best of luck for the future."
