 However, the new revelation about her estimated 6.9% stake in Portuguese oil company GALP combined with some dividends and a rising stock price at ZON, has pushed Isabel dos Santos’ estimated net worth up by another $1 billion to $3 billion after 2013 Forbes Billionaires list came out and she now qualifies as the authentic richest woman in Africa as well as the continent’s youngest.

Dos Santos is something of an enigma who has quickly and systematically garnered significant stakes in Angola’s strategic industries–banking, cement, diamonds and telecom–making her most influential businessperson in her homeland. More than half of her assets are held in publicly traded Portuguese companies, adding international credibility. Isabel has an asset -- worth a conservative $1 billion -- is a 25% stake in Unitel, one of Angola's two mobile phone networks, where Isabel dos Santos is a board member. She also sits on the board of Angola's Banco BIC, where she also has a 25% stake. In Portugal, she owns nearly 15% of ZON Multimedia, a listed cable TV company, and 20% of Banco BPI, one of Portugal's largest publicly traded banks.

At the age of 24 Isabel had her formative business experience when in 1997 she entered into partnership with Rui Barata, the owner of Miami Beach, a rustic chic beach-side bar and restaurant in Luanda, whose business was taking a nosedive. Isabel`s management and cash turned the business around. She then worked as a project manager engineer for Urbana 2000,a subsidiary company of Jembas Group, that won the contract for cleaning and disinfection of the city. Over a period of nearly 20 years she expanded her business interests continuously and this led her to create several holdings, in Angola and mostly abroad, and to make substantial investments in a series of prestigious enterprises, especially in Portugal.
