Legal tech startup Mentat said on Monday it raised 1.1 billion won in seed funding.

Collaborative Fund Asia led the round, with venture accelerator Crypton and financial technology firm HonestAI participating.

Mentat is an artificial intelligence (AI) service that helps lawyers draft legal documents and is set to officially launch as early as late May. It offers two modes: a Fully Self-Driving Drafting (FSD) mode and a co-pilot mode. FSD generates drafts such as complaints, answers and preparatory briefs with only an upload of materials. The co-pilot mode allows lawyers to collaborate with AI by paragraph to complete documents.

The company said an AI agent based on a large language model (LLM) is best suited to reading vast materials, extracting key points and building a logical structure to produce documents spanning dozens of pages. It said a closed beta test involving 60 legal experts cut drafting time by 60 to 95 percent. Mentat aims to redesign how lawyers draft documents, as AI coding tools such as Claude Code and Gemini CLI have changed how developers work.

It will first launch two pricing plans: a usage-based subscription plan for individual lawyers and small and mid-sized law firms, and an enterprise plan for large law firms and legal teams.

Brian Zhang (브라이언 장), head of Collaborative Fund Asia, said the Mentat team has both deep understanding of the legal domain and the capability to build AI products. Mentat CEO Kim Joo-soo (김주수) said the company will build a tool that shares the heavy burden of reviewing materials and drafting so lawyers can focus on what they do best.
