Stelios Haji-Ioannou (Net Worth: $1.63 Billion)
The son of a Greek Cypriot shipping magnate, Stelios Haji-Ioannou gets the bulk of his fortune from his stake in budget airline easyJet. Stelios founded easyJet in 1995 and now maintains ownership of the easy brand through his private company, easyGroup, based in London.
He licenses the brand to such customers as easyHotel, easyCar and easyBus, all of which offer discounted value to customers. In 2017, Stelios joined the Giving Pledge, in which he committed to donate a portion of his annual income each year to various charitable causes.
