RBW

RBW Inc. (Rainbowbridge World; 알비더블유) is a Seoul-based entertainment company and one of South Korea's most strategically ambitious mid-tier labels. Founded on March 5, 2010, by CEO Kim Jin-woo and Chief Executive Producer Kim Do-hoon, RBW grew from a music production outfit into a publicly listed entertainment conglomerate spanning artist management, content production, and label distribution. The company is listed on KOSDAQ under ticker 361570.

RBW's foundational story runs through MAMAMOO, the girl group it launched in June 2014 and shepherded through a decade of releases defined by vocal sophistication and genre range. While individual members have since spread across different agencies for solo careers, the group's output under RBW established the label's reputation as a home for artists who prioritize musicianship above trends. The label also developed Onewe, a rock group that carried RBW credibility with alternative audiences.

RBW's growth in the 2020s was defined by acquisition. The company absorbed WM Entertainment (home of Oh My Girl) and in January 2022 took over DSP Media, one of K-pop's historic agencies and current home of KARD and Young Posse. These moves transformed RBW into a holding group with subsidiaries also including RBW Japan (based in Meguro, Tokyo), content IP management company Contents X, and Urban Works Media. The group employs over 100 people as of 2024. Purple Kiss, signed to RBW, officially concluded activities in November 2025. The company's vertically integrated model -- spanning training, production, marketing, and global distribution -- positions it as a durable player in the evolving K-pop industry.
