WM Entertainment
WM Entertainment is a South Korean entertainment agency and record label specializing in artist management, music production, and K-pop group development, founded in 2008 by former singer Kim Jung-soo (who later changed his name to Lee Won-min) in Seoul.[1][2] The company rose to prominence with the debut of boy group B1A4 in 2011, followed by girl group OH MY GIRL in 2015 and boy group ONF in 2017, establishing itself as a key player in the mid-tier K-pop industry through a focus on vocal-driven acts and creative content.[3] In April 2021, WM Entertainment became a subsidiary of RBW (formerly RBW Entertainment), with RBW acquiring 70 percent of its shares to expand its portfolio in music and entertainment production.[4] This merger integrated WM's roster into RBW's broader ecosystem, which includes artists like MAMAMOO, while allowing WM to maintain operational independence in artist promotion and releases. As of November 2025, WM Entertainment manages a roster featuring active members from its flagship groups, including B1A4's Sandeul, CNU, and Gongchan; OH MY GIRL's Hyojung, Mimi, Seunghee, and Yubin (with YooA and Arin having ended their exclusive contracts with the agency earlier in the year, though the group of 6 continues promotions together); ONF; and the newly debuted girl group USPEER, which released its first single album SPEED ZONE in June 2025, marking WM's first girl group launch in a decade.[5][6] The agency has also handled soloists and subunits, such as former IZ*ONE member Lee Chae Yeon until her departure in September 2025.[7] In early August 2025, significant internal changes occurred when founder and CEO Lee Won-min was dismissed by parent company RBW amid reported internal conflicts, with RBW co-CEO Kim Jin-woo assuming leadership of WM and several key executives also exiting.[7] Despite these transitions, WM continues to emphasize innovative music releases and global outreach, contributing to RBW's overall growth in the competitive K-pop market.Overview
Founding and background
WM Entertainment was established on July 21, 2008, in Seoul, South Korea, by Lee Won-min, a former singer under the stage name Kim Jung-soo and later a manager for the girl group Papaya.[7][8] Prior to founding the company, Lee had experience in the music industry as a performer in the 1990s before transitioning to management roles.[7] The company's name, WM, is derived from the initials of its founder, Lee Won-min.[9] From its inception, WM Entertainment focused on artist management, music production, and broader entertainment planning within the K-pop sector, aiming to nurture and promote talents in a competitive industry.[10] The early operations were based in a modest one-story building in Bangbae-dong, Seocho District, reflecting the company's humble beginnings.[11] In 2021, WM Entertainment became a subsidiary of RBW, marking a significant shift in its corporate affiliation while retaining its core focus on K-pop artist development.[9]Corporate structure and ownership
WM Entertainment functions as an independent subsidiary of RBW Inc., which became its majority owner on March 31, 2021, after completing a sales and purchase agreement to acquire 70 percent of the company's shares from its largest shareholder.[3] This structure allows WM to maintain its distinct branding and operational focus on artist management while benefiting from RBW's broader resources for production and promotion.[4] Post-acquisition, the two entities have integrated select operations, such as shared content production capabilities, to support WM's roster without fully merging administrative functions.[12] The company's leadership has undergone significant changes since the acquisition. Founder Lee Won-min, who established WM in 2008 and served as its primary CEO, was dismissed in August 2025 by RBW amid concerns over declining profitability, internal management difficulties, and disagreements on artist direction.[7] RBW co-CEO Kim Jin-woo subsequently assumed leadership of WM, overseeing its strategic direction as part of a broader restructuring effort.[7] This transition reflects RBW's increased oversight of its subsidiaries to align with group-wide profitability goals. WM's organizational framework is divided into key departments handling artist management, music production and album planning, marketing and promotion, and actor divisions, enabling comprehensive support for its idols, soloists, and performers.[13] These units facilitate end-to-end operations, from talent nurturing to concert planning and media engagements. Following the 2021 acquisition, WM's employee base has contributed to RBW's overall expansion, with the parent company's revenue reaching approximately $36 million in trailing twelve months as of 2025, bolstered by synergies across subsidiaries like WM.[14]History
Early years (2008–2014)
WM Entertainment was established on July 21, 2008, by Lee Won-min, a former singer who had previously performed under the stage name Kim Jung-soo.[9] As a nascent player in the South Korean entertainment industry, the company initially focused on building its roster through strategic signings, marking the beginning of its efforts to carve out a niche in the competitive K-pop landscape.[7] In its pre-debut phase, WM Entertainment began expanding its artist lineup in 2009 by signing soloists such as Taegoon, a contestant from the 2005 talent show Battle Shinhwa, who debuted under the label in January 2009 and pursued music and acting opportunities.[9] Similarly, singer Ahn Jin-kyung, formerly of Baby V.O.X Re.V, signed with the agency in 2009 and released her solo single "Bad Guy" (featuring MBLAQ's Mir) in February 2010, produced independently by WM.[15] These early contracts highlighted the company's initial emphasis on managing individual talents amid resource constraints typical of a small-to-medium-sized agency.[16] The debut of B1A4 in 2011 represented WM Entertainment's first major group venture, with the five-member boy band—comprising CNU, Jinyoung, Sandeul, Baro, and Gongchan—formed through internal training and auditions.[17] To generate buzz, the members were uniquely introduced to the public via webtoon comics on the agency's website starting April 11, 2011, before their official showcase.[18] The group officially debuted on April 23, 2011, performing their lead single "O.K" from the EP Let's Fly on MBC's Show! Music Core, with promotions emphasizing their self-composed elements and youthful, energetic image through music shows and small fan events.[17] Despite these efforts, WM Entertainment encountered operational hurdles as a fledgling entity, including limited financial resources that necessitated independent album productions and reliance on modest-scale promotions rather than large-scale marketing campaigns common among bigger labels.[19] B1A4's "O.K" achieved initial chart success, entering at No. 38 on Soompi's weekly chart in early May 2011 and contributing to the group's strong rookie performance, culminating in a 22nd-place ranking on the Hanteo yearly chart by the end of 2011—the highest for any debut act that year.[20][21] This breakthrough enabled WM to broaden into soloist management, with members like Sandeul beginning individual activities alongside group endeavors by 2014.Growth period (2015–2020)
During the growth period from 2015 to 2020, WM Entertainment expanded its roster and production capabilities, debuting new acts that contributed to the company's rising profile in the K-pop industry through innovative concepts and successful promotions. In April 2015, WM Entertainment introduced its first girl group, OH MY GIRL, with the release of their self-titled mini-album featuring the lead single "Cupid." The group adopted a distinctive fairy tale-inspired concept, blending retro aesthetics with whimsical storytelling, which set them apart from mainstream girl groups at the time and helped establish a dedicated fanbase known as Miracles.[22] This debut marked a strategic shift toward diversifying WM's portfolio beyond boy groups like B1A4, emphasizing fresh visual and musical narratives. OH MY GIRL's trajectory gained momentum with breakthrough hits, including the viral B-side "Dolphin" from their 2020 mini-album NONSTOP, which resonated widely for its catchy melody and emotional lyrics, boosting the group's domestic and international visibility.[23] Building on this momentum, WM Entertainment launched its second boy group, ONF, in August 2017 with the mini-album ON/OFF and the title track of the same name. ONF distinguished itself through an experimental music style that fused effervescent pop, hip-hop, and dance elements with a strong vocal focus, often exploring themes of duality and self-discovery.[24] The group incorporated subunits—ON Team for upbeat, performance-oriented tracks and OFF Team for more introspective, vocal-driven songs—allowing for versatile showcases that highlighted individual member strengths and broadened their artistic range. This approach aligned with WM's emphasis on creative innovation, helping ONF build a niche following despite initial challenges in chart performance. Soloist activities also played a key role in WM's expansion, particularly through B1A4 members branching into individual projects. Sandeul, B1A4's main vocalist, extended his group prominence with a solo debut in October 2016 via the mini-album Stay As You Are, where he demonstrated his powerful vocal range on tracks like the title song, leading to sustained solo promotions and OST contributions throughout the period.[25] These efforts, combined with signings like soloist I in 2017, underscored WM's investment in multifaceted artist development. WM Entertainment's achievements during this era included notable awards and global outreach for its artists. OH MY GIRL secured their first music show win in January 2018 for "Secret Garden" on The Show, a milestone 1,009 days after debut, followed by additional victories such as three wins for "NONSTOP" on M Countdown in 2020 and two for "Bungee (Fall In Love)" on Inkigayo in 2019.[26][27][28] The group also embarked on international tours, including their first Asia fan concert tour in 2018, which expanded their reach across multiple countries. These successes, driven by group promotions, contributed to the company's revenue growth and enhanced its reputation for nurturing talent with unique appeal.Acquisition and recent developments (2021–present)
In March 2021, RBW Entertainment completed the acquisition of a 70% stake in WM Entertainment from its largest shareholder on March 31, establishing WM as an independent label under RBW's umbrella to foster operational synergy by integrating WM's artist discovery and training expertise with RBW's production capabilities, while expanding shared resources for broader content development.[3][4] Following the acquisition, WM Entertainment shifted toward greater emphasis on global market expansion, leveraging RBW's strategic initiatives such as content IP development to promote K-content internationally, alongside enhanced digital content distribution through major partnerships like the 2024 agreement with Kakao Entertainment for music and multimedia dissemination.[3][29] The company also bolstered its actor management division, incorporating RBW's resources to support talents in acting projects amid the group's diversified entertainment portfolio.[30] From 2023 to 2024, WM Entertainment navigated key artist transitions, including the discharge of ONF members from military service in June 2023, which enabled the group's resumption of activities through subunit-like project units and full ensemble comebacks, such as their 2024 Seoul concert series, Canada tour "Be Here Now," and North American "SPOTLIGHT" tour, highlighting renewed promotional efforts under RBW's oversight.[31][32][33] In early 2025, OH MY GIRL members YooA and Arin mutually ended their exclusive contracts with WM on May 8, opting to pursue individual paths—particularly YooA in acting—while committing to continue group activities with the remaining members who renewed their contracts.[6][34] A significant milestone in 2025 came with the debut of USPEER, WM Entertainment's first new girl group in a decade since OH MY GIRL's launch in 2015, confirmed for the first half of the year with pre-debut teasers and concept reveals beginning in March, emphasizing a high-speed, dynamic theme ahead of their June 4 single album "SPEED ZONE."[5][35] In early August 2025, significant internal changes occurred when parent company RBW dismissed founder and CEO Lee Won-min amid reported internal conflicts, with RBW co-CEO Kim Jin-woo assuming leadership of WM and several key executives exiting.[7] In September 2025, soloist Lee Chae-yeon, formerly of IZ*ONE, mutually ended her exclusive contract with WM, concluding her tenure with the agency after joining in 2021.[7]Current artists
