Core Viewpoint - The company "Zhuanzhuan" is officially shutting down its C2C business model, which has been operational since 2015, and is shifting its focus entirely to a C2B2C model, indicating a significant strategic pivot in its business operations [1][9]. Group 1: Business Model Transition - Zhuanzhuan will gradually close its C2C business in three steps: stopping the posting feature on September 24, halting transactions on September 29, and providing after-sales support until October 31 [1]. - The C2C model, which operates on a "person-to-person" basis, has been deemed unsustainable, requiring nearly 200 million yuan in annual subsidies while only contributing 30% to the company's revenue [6][9]. - The new C2B2C model, which involves a "person-platform-person" structure, will allow Zhuanzhuan to offer services such as recycling, quality inspection, and after-sales support [4]. Group 2: Market Position and Competition - Zhuanzhuan's monthly active users (MAU) are significantly lower than its competitor, Xianyu, which boasts over 200 million MAU and a strong user community [8]. - The company has struggled to retain users due to its transactional nature, lacking the community engagement that Xianyu has built through interest-based groups [8]. - Previous attempts to pivot towards a C2B2C model, including the launch of verification services and the merger with another platform, have not yielded positive results, leading to a decline in user engagement [9]. Group 3: User Sentiment and Challenges - User reactions to the closure of the C2C model have been mixed, with some expressing strong attachment to the platform and concerns over increased fees on competing platforms [6]. - The company faces significant challenges in building trust within the C2C space, as issues such as fraud and disputes have been prevalent, leading to a loss of confidence among users [6].
