I'm very much interested in doing a regular feature about entrepreneurs around the world. I'm particularly keen to showcase entrepreneurs of colour but happy to post about people from any background as long as they're doing something interesting and innovative. They don't necessarily have to be loaded yet. So if anybody knows someone who they think I should post about, feel free to drop me a line. Let's kick things off with Nigerian billionaire Aliko Dangote. Dangote is the richest man in Africa and worth $13.8 billion dollars. He owns Dangote cement, the continent's largest cement maker which accounts for a quarter of the Nigerian stock exchange total market capital. He has plants in construction all over Africa. He began his career as a commodities trader and built his Dangote group through interests in flour milling, salt processing, sugar, cement manufacturing, real estate, oil, gas and textiles. For his recent birthday, Dangote bought himself a $45 million dollar Bombardier aircraft.
