French entrepreneur, bathed since childhood in the world of toys and commerce, Jean-Michel Grunberg is the founding president of the Ludendo – La Grande Récré group and creator of many concept stores. He also chairs the association La Grande Récré for Children.

Jean-Michel Grunberg was introduced to trades and catering with his father, Maurice Grunberg, whom he joined in 1978 in the family toy business “La Récré” and who passed on to him the entrepreneurial culture and strong human values.

n 1985, Jean-Michel Grunberg took over the management of the family business and the following year opened the second store “La Récré”. This is the beginning of the development of a chain of medium-sized assisted self-service toy stores that stands out from the competition by whose strengths are the availability of products associated with quality services. In 1994, Jean-Michel created the brand “La Grande Récré” which in a few years became a national brand (67 stores in 2000). Six years later, he united all of his group’s brands under the corporate brand Ludendo, which today has nearly 200 stores. La Grande Récré has been part of the HPB brand collection since October 2018.
