Zhihu (Chinese: 知乎; pinyin: Zhīhū) is a Quora-type question and answer site and news aggregator.

[8][9] It has reportedly received funding from Kai-Fu Lee's Innovation Works, Qiming Ventures,[10] SAIF Partners, Tencent, and Sogou.

In August 2018, Zhihu completed its E-round of funding, raising US$270 million for a total company valuation at US$2.5 billion.

On August 12, 2019, Zhihu completed a subsequent F-round of funding led by Chinese short video platform Kuaishou and technology company Baidu, garnering US$450 million.

All shares were transferred to the founder and CEO, Zhou Yuan (Chinese: 周源; pinyin: Zhōu Yuán), who owned more than 99% of the company thereafter.

This occurred three days after regulatory pressures from the Beijing branch of the Cyberspace Administration of China (CAC), during which Zhihu was instructed to rectify practices that had led to unlawful release of information.
