Writers signed to the company include Norwegian songwriting team Dsign Music, responsible for songs such as Girls' Generation's "Genie", NCT Dream's "ISTJ" and Taemin's "Want", and Sweden-based duo Sunshine, responsible for Red Velvet's "Psycho" and Aespa's "Spicy".

KMR also acquired the South Korean production teams MonoTree and The Hub, joining the Kangta-led Smash Hit as CICs (company-in-company).

It has plans to establish a North American subsidiary and form additional partnerships with local companies.

SM refuted this, explaining that The Hub showed rapid sales growth and 10x was part of its plan to establish a label.

[11][12] In September 2024, Kangta said that SM had released around 170 songs through KMR since its establishment, and that it was saving them up to 60 billion won per year in copyright and publishing fees.
