Zhihu, the largest question and answer platform in China, has raised a $434 million Series F. This is not only the company’s biggest round since it launched in 2011, but also one of the largest secured over the past two years by a Chinese internet culture and entertainment company, said China Renaissance, which served as the funding’s financial advisor.

The Series F was led by Beijing Kuaishou, the video and live-streaming app, with participation from Baidu . Existing investors Tencent and CapitalToday also returned for the round, which Zhihu will use for technology and product development. Baidu told Bloomberg that it will add 100 million Zhihu posts to its main app.

While Zhihu has downplayed reports that it is planning an IPO, it embarked on plans to hire a CFO and restructure last year.

Zhihu users tend to be educated with relatively high incomes and the platform has developed a reputation for hosting experts and organizations that are knowledgeable in tech, marketing and professional services like education. Like Quora and other Q&A platforms, Zhihu lets users post and answer text-based questions. But it also has other features, including discussion forums, a publishing platform and live videos for brands and companies to answer questions in real time. Instead of making its streaming video feature, called Zhihu Live, open to all users, it is available only to experts and organizations, differentiating it from other streaming apps like Douyin, the domestic version of TikTok (ByteDance is an investor in Zhihu but did not participate in this round).

In a post about the round on his Zhihu page, founder and CEO Victor Zhou wrote the company plans to keep up with rapid changes in China’s media and internet landscape. “Over the past 8 years, users have gone from expecting simple entertainment to using the Internet to deal with real-life and work problems. The focus of competition has also shifted from traffic to traffic + quality.”
