A Virtual YouTuber agency founded by ZIZAI (then DUO Inc.), the company behind the Mirai Akari Project. It functioned akin to activ8's virtual talent support 'group', project upd8, where ENTUM aided its endorsed VTubers with the creation of content, planned collaborations and events, served as spokespersons for the media and provided a physical address for fans to send correspondence.
ENTUM would shut down at the end of 2019, with its talents either also retiring, going independent, or finding new agencies.
