Isabelle Leleux

Client Services


Isabelle is the ‘glue’ between the clients and the agency. It’s her job to understand exactly what the clients need and to deliver the real ‘mad about you’ experience. In doing so, she has successfully led projects from strategy to execution for BASE Company, DEME, InBev, PSA, Solvay, Triodos Bank, Janssen Pharmaceutica, Euroclear and many more.

How she got there? After a bit of a wild start as a waitress in a cocktail bar in Mykonos, she decided to make use of her master in communication sciences and started working for agencies such as Beluga, Duval Guillaume & true.agency, to finally become a partner at mad about you. Apart from that, she is also mad about Bruce Springsteen, the one and only Boss on earth…

Evert-Jan De Kort

Brand Strategy


Evert-Jan is always eager to tackle complex projects through open-minded thinking, structure and strategy. The world of brands opened up to him working at advertising agencies Euro RSCG/Havas and then Duval Guillaume, where he worked as digital creative & strategist across departments.

He went for the world beyond the campaign joining research firm InSites Consulting. As a digital marketing consultant he explored opportunities and trends  for local and international clients to help them perform better. At true.agency he introduced a ‘brand culture’ philosophy and collaborated with Innate Motion on more complex branding projects. And now he’s looking forward to reflect your brand’s being and doing, because he wants to be mad about you.
