NetEase launched their first Western Headquarters in August 2014 bringing one of the largest tech companies in China to the US. In 2015, NetEase North America, the San Francisco-based arm of the Chinese technology giant, announced a new funding initiative for independent developers. Known as the NetEase Success Fund, the scheme offers an alternative to traditional publishing by providing up to $500,000 for each accepted developer to fund marketing and advertising. Furthermore, developers awarded funding retain the rights, creative control, and full ownership of their products. In December 2015, NetEase Capital Venture arm has made a $2.5 million investment into Reforged Studios, a privately held game studio based in Helsinki.

NetEase has an on-demand music-streaming service; 网易云音乐 (roughly "NetEase cloud music").

NetEase's URL is 163.com. This is confusing to many non-Chinese because there seems to be no logical connection between the firm and its URL. While the URL might seem to be a case of Chinese numerology, it is not. Rather, the URL exists because of recent Chinese history: before the availability of broadband internet, users had to dial 163 to get online. Therefore, early internet users recognized the numbers as implying a way to access the internet.
