05 / WHO YOU WORK WITH

SUNGMIN KIM / FOUNDER & EDUCATOR

Before applying, meet the person you would work with.

“I want to build systems that carry great teacher judgment further, not answers that replace teachers.”

Years of teaching mathematics showed me how one strong explanation or one well-built question can reshape a student's thinking. Trinity EduLab builds systems that extend educator judgment rather than replace it.
