About Jiamian Tech

Jiamian Tech, officially known as Shanghai Jiamian Information Technology Co., Ltd., was established in Shanghai, China, in 2014. The company was founded by Xu Weifan and Yang Liu, who are recognized as part of the first generation of mobile internet product managers in China. Jiamian Tech operates as a subsidiary of the Sina Group and specializes in developing social networking and entertainment products, with a focus on interactive entertainment scenarios.

The firm has developed over 40 products, reaching a user base of more than 200 million. Its portfolio includes the first mobile version of the popular social deduction game "Werewolf" (狼人杀), which gained significant traction after its launch in 2016, surpassing 80 million users by 2018. This application facilitates social interaction by placing users in a game-based scenario, encouraging communication and deduction to foster connections among strangers. Other notable products include "Who is the Undercover" (谁是卧底), "Fotorge" (足记), and the hyper-casual game "Super Egg Laying Duck" (超能下蛋鸭). The business model centers on creating engaging social and entertainment platforms that monetize through user interaction and in-app features. The company targets the younger generation, particularly post-95s and post-00s, who have a strong demand for online social entertainment and anonymous social networking.

Financially, Jiamian Tech has attracted investments from prominent institutions such as GSR Ventures, Giant Network, Kunlun Wanwei, and Hongtai Fund. In 2020, the company was acquired by Weibo (WB.US), becoming a controlling subsidiary of the social media giant. In addition to its own product development, Jiamian Tech has an active investment arm, supporting upstream and downstream enterprises. Its investment portfolio includes the gaming industry media outlet GameGrape (游戏葡萄) and Yunrui Network, which holds the intellectual property for "Werewolf®".
