RBW Entertainment (Rainbow Bridge World) was founded in 2010 and built its reputation on MAMAMOO - one of K-pop's most critically acclaimed groups, celebrated for powerful vocals and retro-influenced artistry. The company has since expanded its roster with ONEWE, ONEUS, Purple Kiss, and others. RBW is known for giving its artists notable creative freedom, particularly evident in MAMAMOO's theatrical performances, jazz-influenced production, and members' self-written material.
