History
WM Entertainment was founded in 2008 by former South Korean singer Kim Jung-soo, who formally changed his name to Lee Won-min before establishing WM Entertainment.
The company was originally operated in a one-story building located in Bangbae-dong, Seocho District. In August 2014, Lee Won-min purchased a six-story building located in Mangwon-dong, Mapo District named Daemyung Tower Building for KR₩4.33 billion (approximately US$3.85 million), which functions as the current headquarters for WM Entertainment.
Almost a year after its foundation, WM Entertainment signed up Battle Shinhwa alumnus Taegoon. H-Eugene and Baby Vox Re.V member Ahn Jin-kyung joined the company in 2010.
WM Entertainment debuted their first boy group B1A4 on April 23, 2011.
WM Entertainment's first girl group Oh My Girl debuted on April 21, 2015.
WM Entertainment debuted soloist I (sister of B1A4 member Baro) on January 12, 2017.
WM's second boy group ONF debuted on August 2, 2017.
On April 7, 2021, it was announced that WM Entertainment had 70% of its shares bought by RBW, which houses idol groups such as Mamamoo, Oneus, and Onewe. WM became a subsidiary of RBW.
On March 24, 2025, it was confirmed that WM Entertainment would launch the girl group Uspeer by the first half of 2025. The group was the company's second girl group in ten years, after Oh My Girl. WM would later acquire 257 Entertainment, the entertainment company of XLOV, in March 2026. 257 Entertainment would later integrate with WM Entertainment and change their name to StrangeLab Inc. and Oh My Girl would switch to DSP Media in August 2026.
