We’ve come a long way

Since Keesing was founded in 1911 by Amsterdam-based journalist Isaäc Keesing, we have grown into the European 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 books in different languages. Keesing France, established in 1955, has been especially successful with its brand Sport Cérébral.

Since our early days, Keesing has flourished thanks to its family-owned dedication to business. In 2004, NPM Capital acquired a 100% share in Keesing. With its ongoing success and visibility, Keesing was purchased in 2006 by TMG (Telegraaf Media Groep), one of the largest Dutch media groups. This ensured our continued future growth, that was built on a strong foundation. And in 2017, Ergon Capital acquired Keesing.

With our unmatched enthusiasm and expertise, KMG has become Europe’s largest publisher of puzzles and braintainment games. And we keep expanding. We continue to develop a growing range of puzzle magazines all over Europe and beyond. And just as importantly, we keep expanding into more markets in print and digital format.
