Hugo Mulliez | Grandson of Gérard Mulliez – Auchan

Net worth: $37.5 billion

Hugo Mulliez comes from a wealthy French family. His grandfather, Gérard Mulliez, allocated investments and founded the supermarket Auchan in 1961. For those of you who are not familiar with the name, Auchan is the counterpart of America’s Walmart in France. It has franchises all over the world, including countries like Hungary, Italy, and Spain, among others. It is one of Europe’s biggest supermarket chains. Hugo is the son of Anne-Sophie Watine and Arnaud Mulliez, the former Chief Executive of Auchan France.

Hugo was born in northern France in the city of Lille together with his siblings Alexandre and Margaux. The Auchan heir met his now-wife Jessica in middle school. They grew up together and ended up studying business together as well. They have been together since 2010 and tied the knot in 2016. Hugo founded Artsper, an online platform for contemporary art sales.
