Just weeks after the U.S. placed a unit of SenseTime Group Inc. on a blacklist for alleged human rights violations, the firm is about to make founder Tang Xiao'ou one of the world's richest people. China's largest artificial intelligence company priced its initial public offering at HK$3.85 (49 cents) per share, raising $5.55 billion. That was the bottom of the expected range, but a signal that despite increased tensions with the U.S. and Beijing's crackdown on tech giants, the country, including its vast surveillance machinery, continues to churn out huge fortunes and massive gains for venture capitalists. Tang, 53, a Massachusetts Institute of Technology graduate and information engineering professor at the Chinese University of Hong Kong, holds a 21% stake in the company and is worth $3.4 billion, according to the Bloomberg Billionaires Index. A representative for SenseTime declined to comment on Tang's net worth.
