Jellyfish Entertainment

Jellyfish Entertainment is one of the more distinctive second-wave K-pop companies because it built its name on vocalists and concept discipline before most mid-sized labels started chasing scale at any cost. Founded in 2007 by producer Hwang Se-jun, the Seoul company moved from ballad and OST strength into idol management, acting, publishing, and performance production without losing its house taste for polished melodic work.

That identity still runs through the roster. Legacy acts such as VIXX shaped the label's reputation, while VERIVERY carried its performance-focused idol lane into a new generation and Kangmin opened a solo chapter in 2026. Jellyfish does not operate like a Big Four volume machine. It leans on tighter artist development, a smaller public roster, and long-cycle branding that can still cut through when the material is right.

That makes Jellyfish worth tracking even in a crowded market. It remains a useful read on how a mid-sized Korean label survives: protect a recognizable sound, move selectively, and keep enough flexibility to let singers, actors, and idol acts coexist under one banner.
