Since Keesing was founded in 1911 by Amsterdam-based journalist Isaäc Keesing, we have grown into the global market leader in print, online, and app puzzle formats. After he became successful with his financial archives, Keesing launched his own publishing house in 1916.
When Isaäc Keesing introduced Denksport, the first puzzle magazine in the Dutch market, it set off a new puzzle-playing craze and the brand quickly became a household name.
After 1945 Keesing expanded by publishing puzzle magazines in different languages. Keesing France, established in 1955, has been especially successful with its brand Sport Cérébral.
Our unmatched enthusiasm and expertise have helped Keesing become the world’s largest publisher of puzzles and braintainment games. And the story continues. Our ambition is to bring Braintainment to everyone, so we keep expanding and developing puzzle magazines all over the globe. And just as importantly, we keep moving into more markets in print and digital format.
