KT Millie Seojae operates 'Millie's Library', a subscription platform that gives readers unlimited access to a large catalogue of e-books, audiobooks, and other digital reading formats for a recurring fee.

It serves individual consumers directly, corporate and public-sector clients through business-to-business channels, and broader audiences through partnerships with telecoms carriers. Listed on KOSDAQ, Korea's tech and small-cap board, the company's core business is built around subscription revenue rather than per-title purchases, and it has expanded into user-generated fiction, webtoons, and AI-powered reading features.
