About BY4M

BY4M (by4m.kr) is a comprehensive entertainment company based in South Korea that has rapidly evolved since its establishment in 2017. The company was founded by CEO Yoo Kwi-sun. Initially an advertising agency, BY4M leveraged its expertise in digital marketing and its own social media channels to expand into a multifaceted content powerhouse. The firm now operates across a wide range of business areas including entertainment, publishing, video production, music production, and film distribution.

The company's business model focuses on a one-source multi-use (OSMU) strategy, creating and managing intellectual property across various formats like films, dramas, music, webtoons, and publications. BY4M generates revenue through film investment and distribution, music content management, publishing, and digital advertising services. The firm has gained significant attention in the film industry by successfully distributing several box office hits, challenging the dominance of major Korean distributors. A notable strategy includes acquiring films that larger distributors might shy away from and using aggressive, data-driven online promotion to target audiences.

Significant milestones include successful film distributions for "The Firefighters," "Hitman 2," and "The Match". In 2019, BY4M entered the publishing business and achieved major success with the Korean versions of KADOKAWA's novels. This led to the establishment of a joint venture with Japan's KADOKAWA CORPORATION in March 2024 to translate and publish Japanese content in Korea, with KADOKAWA acquiring a 55% stake in BY4M's spun-off publishing division. The company has also expanded into talent management, establishing 'ABM COMPANY' in 2025 to discover and develop new actors, moving towards becoming an IP incubation platform.
