Klaus runs Duval Union as a Founding Partner. Klaus started his career in the advertising industry and worked for Quattro (which later became Saatchi), TBWA, and Duval Guillaume, where he served first as Managing Partner and later as Duval Guillaume’s CEO (as of 2009). He oversaw a period of rapid growth for the agency – a time during which the business grew from five to 250 employees while generating a gross profit at peak of c. €30 million and over €50m in sales. Under Klaus’ brinkmanship, Duval Guillaume won many awards, including 17 Effies, during a 10-year time span in total. A unique feature in the Belgium advertising scene. Between his role as CEO of Duval Guillaume and co-founding Duval Union, Klaus founded his own business – Dreams & Fears, offering research-based marketing strategy to blue chip clients.
