Mark Dixon founded IWG, then called Regus, in 1989.
The father-of-five had the idea after noticing the lack of office space for travelling business executives meeting at tables next to him in a Brussels café.
Essex-born Dixon, who lives in Monaco, started Dial-a-Snack, which delivered sandwiches, after he left school.
But the business failed and he went travelling before returning to Essex to buy a burger van.
He set up The Bread Roll Company to solve supply issues and sold it for £800,000 in 1988. He relocated to Brussels, where he started Regus.
