Trizen Medical raises ￥100M in Series B funding for its medical LLM "Trizen AI"

Recently, Trizen Medical, one of China's earliest innovators in the post-training of medical LLMs, announced the completion of a RMB 100 million Series B funding round. In Q4 2024, the strategic investment was led by A-share listed company Innovative Medical (SZ.002173). In Q2 2025, the Series B round was completed by Good Doctor Group, with Probe Capital acting as the exclusive financial advisor for this round.

Simultaneously, Trizen Medical disclosed that its flagship LLM application, "Trizen AI," has demonstrated outstanding performance in the "Medical LLM + AI Application" sector.

From January to October 2025, Trizen AI achieved a significant lead in contract value with various hospitals and medical groups across China in core medical AI application areas such as "Intelligent Medical Records" and "Patient Services." The contract value grew tenfold compared to the full year of 2024, with an expected annual growth of 12 to 15 times by the end of 5. Alongside rapid business expansion, the number of physician users on Trizen AI has seen exponential growth, establishing it as a benchmark product for commercial implementation in the medical AI field.

Dr. Xue Chong, founder of Trizen Medical, stated: "From its inception, Trizen Medical has been committed to a singular goal: freeing doctors from tedious tasks and leveraging AI to enhance their clinical capabilities, allowing them to focus more on diagnosis and treatment. That's why we developed 'Trizen AI,' an AI physician assistant, aiming to start by addressing the high-frequency pain point of medical record documentation to improve both physician efficiency and healthcare quality. Trizen AI serves not only as a medical record transcription assistant but also as an aid in clinical decision-making and medical risk prevention. It further extends a doctor's non-core professional capabilities, such as AI-assisted medical insurance coding. We believe that only by integrating AI into clinical workflows alongside doctors can AI truly engage with and comprehend real-world medical scenarios, ultimately leading to the post-training of AI physicians with advanced clinical diagnostic thinking."

Following this funding round, Trizen Medical will continue to increase its R&D investment to upgrade the personal physician edition of Trizen AI and enhance the performance of its large language model for medical applications. This will provide more comprehensive and professional AI support for doctors and hospitals, including assistance with clinical research (e.g., data collection, organization, and follow-up), competency training (e.g., AI-assisted learning and virtual patients), and clinical decision support (e.g., literature/guideline retrieval and summarization).
