China's SenseTime, the world's highest-valued AI startup, closes $620M follow-on round

SenseTime, the world's highest-valued AI company with a valuation of over $4.5 billion, is back in the money again. The company raised $600 million in an Alibaba-led financing round announced last month, and now it has added a further $620 million to that with a "Series C " round announced today. Alibaba led the previous deal, and this time around the investors include more traditional names such as Fidelity International, Hopu Capital, Silver Lake and Tiger Global. Qualcomm, which previously backed the firm, was also in this round, SenseTime confirmed. The new money takes SenseTime to $1.6 billion from investors to date.
