Seed round from Kakao Ventures and Schmidt

Yeji X announced a seed investment from Kakao Ventures and Schmidt. Terms were not disclosed.

The company was founded by CEO Seonghyeon Jeong, previously CEO of Promedius, which commercialized Korea's first osteoporosis AI solution. Yeji X's core technology is a multimodal foundation model that reads a patient's EHR data and medical imaging together to predict 30-day hospital readmission risk for heart failure — a condition with persistently high readmission rates.
