Zhihu

Zhihu began development starting from August 2010. It went through a closed beta test at the end of December 2010. The final product went online on January 26, 2011. It has reportedly received funding from Kai-Fu Lee's Innovation Works, Qiming Ventures, SAIF Partners, Tencent , and Sogou.On August 12, 2019, Zhihu completed a $450 million F-round funding led by Chinese short video platform Kuaishou and internet giant Baidu.In December 2021, ten of Zhihu's shareholders, including Sogou and Tencent's investment arm, sold their entire stakes in Beijing Zhizhe Tianxia Technology, the parent company of Zhihu. All shares were transferred to the founder and CEO, Zhou Yuan, who owned more than 99% of the company thereafter. It was reported that the move was driven by regulatory pressures from the Beijing branch of the Cyberspace Administration of China after the institution had summoned Zhihu to rectify practices that had led to unlawful release of information.Zhihu's initial public offering on the New York Stock Exchange came on March 26, 2021. Zhihu started trading on the Hong Kong Stock Exchange on April 11, 2022.
