Company Performance Metrics
Mentat is an AI book licensing platform that connects book publishers with AI companies in South Korea and globally. Founded in July 2025 and headquartered in Seoul, Mentat addresses one of the most urgent problems of the generative AI era: how publishers can monetize their book content for AI training and citation while maintaining copyright
protection.
The platform operates two complementary business models. The first is training data licensing, where AI companies bulk-purchase book content as JSONL datasets to train their large language models. This follows the pattern set by global precedents — HarperCollins ($5,000/title with Microsoft), Wiley ($40M AI licensing revenue in FY2025), and Taylor & Francis ($75M from two AI partnerships). The second is RAG citation licensing, a usage-based recurring revenue model where AI chatbots cite specific book passages in their answers, and publishers earn fees per citation. This is the music-streaming analogy of AI book licensing: instead of one-time CD sales, publishers receive ongoing revenue every time their books are referenced.
Mentat handles the entire workflow end-to-end: copyright clearance with publishers, secure encrypted file distribution to prevent unauthorized copying, JSONL conversion for training data, a RAG citation API for AI companies, usage tracking, and automated revenue settlement to publishers and authors.
The company currently hosts over 21,000 titles through a partner network of 157 publishers across general books, academic, and periodical content — the largest book-focused licensing inventory in Korea aligned with AI use cases. Beyond publishers, Mentat works directly with authors who want to express AI licensing intent ahead of their publishers, providing meaningful leverage for contract negotiation and fair revenue sharing.
Mentat is an Antler Korea portfolio company (invested July 2025) and a TIPS-selected startup, a competitive Korean government R&D grant program for early-stage technology startups. The team is led by CEO Byungwook Jeon and CTO Geonhui Kim, a serial founder with two successful M&A exits.
Mentat targets three customer groups: (1) Korean and global book publishers seeking new AI-era revenue streams from their existing catalogs; (2) AI companies — including LLM providers, RAG-enabled chatbots, and enterprise AI vendors — that need legally licensed Korean book data to reduce hallucinations and eliminate litigation risk; and (3) authors who want to ensure fair compensation when their books are used by AI systems.
The platform's competitive moats include the largest network of contracted Korean publishers in the AI licensing space, end-to-end infrastructure (encryption, RAG retrieval, settlement) that competitors cannot replicate quickly, regulatory positioning aligned with Korea's emerging AI copyright framework, and dual revenue models that combine one-time training data deals with sustainable per-citation revenue.
Mentat's vision is to become the global infrastructure layer between books and AI — ensuring that as AI consumes more written content, publishers and authors receive sustainable, transparent, and fair compensation.
