Isabel dos Santos net worth: Isabel dos Santos is Angolan businesswoman who has a net worth of $3.5 billion. Isabel dos Santos, also known as the oldest daughter of Angola's President José Eduardo dos Santos, was named Angola's first billionaire and the richest woman in Africa as of March 2013. It was in 1977, when the 24-years-old Isabel started her first business, i.e., a restaurant called Miami Beach in Luanda, the country's capital. Dos Santos has come a long way ever since she made her kick-off through her business establishment serving food and drink. Today, she has a seat
on the boards of several Angolan and Portuguese companies and is one of the key people in making business decisions. Even though her representatives firmly claim that her fortune is self-made and doesn't have any association with her father, a recent research implies that President dos Santos has transferred shares in several of her holding companies. Mrs. Dos Santos is the biggest stakeholder in Zon, a Portuguese media conglomerate; she owns almost 20% of Banco BPI, Portugal's largest publicly traded banks; as for her most valuable asset, it is a 25% stake in Unitel, one of Angola's two mobile phone networks, where Isabel is also a board member. In her off-business side of her life, she is a wife and a mother of three.
