Chairman, Huawei Technologies, 60
Sun, Huawei’s chairwoman for seventeen years, worked as a state radio factory technician and engineer before joining Huawei in 1989. Under her leadership, Huawei has become the third-largest smartphone maker in the world, trailing only Samsung and Apple. The Shenzhen-based company posted $62.9 billion in revenues last year, nearly 60% of which came from sales in Europe, Africa, and the Middle East. As carriers around the world are installing faster fourth-generation wireless networks—mostly for watching high-quality videos—Huawei’s networking equipment business is booming.
