Core Viewpoint - The article discusses the challenges and failures associated with the co-CEO model in the Chinese internet industry, highlighting the case of Himalaya and other companies that have adopted this structure, ultimately questioning its effectiveness in a fast-paced and competitive environment [1][2][3]. Group 1: Co-CEO Model Challenges - The co-CEO model can lead to inefficiencies, decision-making delays, and internal conflicts due to shared responsibilities and differing strategic visions [1][2][3]. - Companies like Himalaya, Bitmain, and Kuaishou have experienced significant struggles under co-CEO leadership, often resulting in strategic misalignment and operational chaos [3][5][6]. - The co-CEO structure may initially provide stability during transitions, but it often fails to deliver long-term success in the rapidly evolving tech landscape [1][2][3]. Group 2: Case Studies - Himalaya, despite having a strong market position with approximately 300 million MAU and 60% of mobile audio listening time in China, faced four failed IPO attempts and struggled with monetization [2][3]. - Bitmain's co-CEO model led to internal strife and a decline in market position, with the company failing to adapt to competitive pressures and ultimately stalling its IPO process [5][6][8]. - Kuaishou's dual leadership initially thrived but later faced challenges as the need for decisive action increased, leading to a restructuring of its management [22][25]. Group 3: Conditions for Success - Successful co-CEO arrangements are rare and typically require clear division of responsibilities, mutual respect, and a higher authority to make final decisions [17][29][30]. - In stable industries or during transitional phases, co-CEO structures may provide temporary benefits, but they are less effective in the dynamic and competitive environment of the internet sector [28][30][31]. - The article suggests that co-CEO models may work better in companies with distinct, independent business lines or where one leader has ultimate decision-making authority [29][32].
