Zhou Qunfei is the leader of Lens Technology, a touch-screen manufacturer with a customer list that includes Samsung and Apple. Starting out as a low-wage factory worker, Qunfei now oversees a workforce of 60,000. After going public on China’s Shenzhen Stock Exchange on March 18, the company’s share price quickly rose by more than 300%, earning Qunfei the titles of richest woman in the global tech field and richest self-made woman. She is currently worth an estimated $10.2 billion. With her technology featured on the Apple Watch introduced back in April, that number is only expected to grow.
