Created in 2004 in France by Cédric Barbé and Patrice Boulet, today IELLO is a globally recognized board game publisher and distributor.
The business has grown from mail order collectible cards to acting as a wholesaler distributor. In 2008, it diversified again by beginning to co-publish, a work that includes translating and adapting games to the French culture.
This new activity naturally evolved in 2009 into its current state: publishing their own games. In 2011, King of Tokyo™ became the first game developed and distributed by IELLO. The success of this activity became so large that, in 2018, the amount of publishing was 90% internal creations and 10% co-publishing. This growth allowed IELLO to create new best-sellers, such as Kanagawa™, The Big Book of Madness™, Bunny Kingdom™, Welcome to the Dungeon™, and more!
