[1] The company was previously partnered with Shinchosha until 2010 and then with Tokuma Shoten until Coamix began self-publishing in 2020.
The company was founded on June 4, 2000, by former Weekly Shōnen Jump editor-in-chief Nobuhiko Horie (who currently serves as the company's CEO), along with manga artists Tsukasa Hojo, Tetsuo Hara, and Ryuji Tsugihara, and voice actor Akira Kamiya, among others.
Since 2012, Coamix had been organizing "SILENT MANGA AUDITION", an open competition for Japanese style comics, without spoken dialogues.
The organizer claims that utilizing graphics only for story telling, is a great test and training for manga creative skills.
The winners of the event have made commercial debuts on Japanese comic magazines, with some gaining future prospects for series production.
