JK

JK is Liu Jingkang (刘靖康), the 1991-born founder of Insta360影石, which he established in 2015 . He has described DJI founder Frank Wang (汪滔) as a "worthy rival" and competes directly with DJI in the imaging hardware space . As of a September 2025 暗涌Waves profile, Insta360's market capitalization had surpassed 100 billion RMB, making Liu one of China's youngest leaders of a trillion-yuan market cap company . The same profile quoted him acknowledging that the company "earns hard money" and that its organization lacked self-upgrading mechanisms, signaling introspection about operational challenges even at scale . Earlier coverage from 暗涌Waves in 2024 highlighted his unconventional path: as a Nanjing University student he once hacked the academic affairs office email system and cracked Zhou Hongyi's phone number by analyzing keypad tones .
