The top Chinese female technology entrepreneur was Hong Kong-based Zhou Qunfei, 45, chairwoman of Lens Technology Co, who rose to 30th with a net worth of $7.5 billion.
"Zhou Qunfei already had a lot to be proud of going into 2015," wrote Russell Flannery, Shanghai bureau chief for Forbes China. "Zhou quickly notched up an accolade after the stock's trade debut on March 18 by becoming the richest woman in the global tech industry. With the passing of a month and a more than 300 percent rise in the company's share price, the one-time factory worker has achieved another milestone: Zhou is also the world's wealthiest self-made woman."
The world's richest man, Bill Gates, 60, topped the tech list with a net worth of $79.6 billion. He left Microsoft last year to focus on philanthropy and continued to sell shares of the company. It is estimated that less than 13 percent of his wealth at present comes from Microsoft's stock.
Second on the global tech rich list was 71-year-old Larry Ellison, founder of database software company Oracle, with an estimated net worth of $50 billion. He stepped down as CEO last year but still serves as the company's chairman and chief technology officer. Oracle's total sales revenue dropped slightly to $38.2 billion in fiscal year 2014, which ended in May.
Online retailer Amazon.com not only surprised analysts with $92 million in profit reported in the second quarter, but also helped its 51-year-old CEO, Jeff Bezos, come in third with an estimated net worth of $47.8 billion, up $13 billion since the beginning of the year. More than 90 percent of Bezos' wealth comes from his 18 percent stake in Amazon.
