On a spring afternoon, Xavier Niel enters the boardroom of Iliad SA, the Paris-based telecommunications firm he founded two decades ago. He’s wearing a white dress shirt and jeans, the same outfit he’s sported with Steve Jobs–like regularity for years. With his longish hair and rumpled attire, he looks more like a hacker who’s blundered into the wrong office than a man who’s worth $10.5 billion.

Niel takes a seat at the head of a white conference table. The glass-enclosed suite feels like an aerie suspended above the city, with a panoramic view of the Eiffel Tower on one side and the rooftops of Montmartre on the other. The only objet d’art in the room is a black brick-shaped box mounted like a conversation piece on top of a coffee table.
