C-JeS Entertainment

C-JeS Entertainment (now operating as C-JeS Studios since April 2023) is a South Korean entertainment company founded by Baek Chang-ju on December 21, 2009. The agency was built from the ground up to manage JYJ -- the trio of Kim Jaejoong, Park Yoochun, and Kim Junsu -- who split from TVXQ after filing a landmark lawsuit against SM Entertainment over contract terms. When the Korean entertainment industry effectively blacklisted the three artists, Baek invested heavily in rebuilding their careers and public credibility outside the traditional system. Over time, C-JeS evolved far beyond its origins as a K-pop management firm. The company expanded into actor management, building a roster that has included Lee Jung-jae, Ryu Jun-yeol, Ra Mi-ran, Sul Kyung-gu, Teo Yoo, and Lee Jae-wook. It also branched into drama production and film distribution through subsidiaries C-JeS Content Tree, C-JeS Culture, and C-JeS Production, developing projects across Korean streaming and broadcasting platforms. In April 2025, C-JeS announced it was exiting actor management to concentrate on music and content production. The active music roster includes girl group WHIB (2023-present), hip-hop artist Crucial Star, singer-songwriter Noel, and vocalist Hong Dae-kwang. The company continues to operate out of its Gangnam headquarters while maintaining a presence in Los Angeles.
