## About

Based in Seoul, South Korea, Yeji X offers an AI-powered medical software that assesses cardiovascular patients' readmission risks using their health records. In October 2025, Yeji X raised an undisclosed amount in seed funding from new investors Kakao Ventures and Schmidt. Founder Jung Sung-hyun is leading the firm as CEO as of 2025.

Yeji X has developed a multimodal foundation model that integrates electronic health records and medical imaging to predict the likelihood of heart failure patients being readmitted within 30 days. This predictive algorithm enables hospitals to identify high-risk patients before discharge, allowing for targeted interventions that improve patient outcomes and reduce penalties under programs like Medicare’s Hospital Readmission Reduction Program.
