About Maarten Keyen’s Current Company
Mindshare Belgium

We’re at the very heart of the most exciting business on the planet – media. Every aspect of human life has been transformed by changes in the media and we are living in the most exciting period the world has ever seen. More technology. More speed. More channels. We’re having fun with more words, pictures and stories than we could ever have dreamed of.This is why we say out loud: EVERYTHING BEGINS AND ENDS IN MEDIA. We believe brands aren’t simply driven by an idea or ideals. A brand’s value is driven through a series of exchanges with people. We use insights and analytics to map this value exchange and to design a growth strategy and infuse this strategy with creativity to invent communications ideas. Hereto ORIGINAL THINKING is fundamental in everything we do: how and where we work; how we trade; what tools we design; how we generate insights; how we develop ideas. If it’s been done before, it is not good enough. If you’ve seen it before, think again. That's our spirit!
