Mark Dixon, the billionaire founder of Regus Plc, the world’s largest operator of serviced offices, has more than doubled his fortune in the past year as increased demand for flexible office space propelled the company’s share price to an all-time high. Regus shares have surged 106 percent since last October, compared to a 30.3 percent gain in the FTSE 250 index. Dixon, 53, owns a 34.2 percent stake in the company valued at $1.1 billion, according to data compiled by Bloomberg. Dixon founded Regus in Brussels, in 1989. A high-school dropout, he moved to Belgium after selling a U.K. bakery, The Bread Roll Co. While looking for an office in the capital, he was struck by the number of professionals working out of cafes and hotel lobbies. Brussels became the site of the company’s first business center.Source: Bloomberg.com
