Company profile
researched Aug 2026Mildang, operating under the brand 밀당PT, provides one-to-one online "personal teaching" for South Korean middle and high school students. Its positioning centres on the argument that stagnant grades stem from students' study methods rather than the volume of study, and the service is presented as an alternative to conventional private tutoring (사교육).
The company's site organises intake by school year, offering free consultation requests for parents of students from the fifth and sixth years of elementary school through the three years of middle school, the three years of high school, and repeat exam-takers (N수생). Consultations are requested through a form that collects the student's grade level and the applicant's mobile phone number, with mobile identity verification and consent to personal-information collection; the data is retained for one year and optional consent covers marketing communications.
Business model
Mildang sells 1:1 online teaching directly to families of school-age students, with prospective customers entering through a free consultation request that captures the student's year group and a contact phone number for follow-up.
Traction
The company's site presents named student outcome cases, including two sisters admitted to medical school in consecutive 2025 and 2026 admissions cycles, a student who moved from a 4th-grade to a 1st-grade school record and gained SKY-level university admission with offers from Yonsei, Sungkyunkwan and Ewha Womans universities, a student who became top of their school and entered Korea University, and a student who reached all top grades within a year and entered KAIST on a full scholarship. The site states these cases are based on 2024 internal data and that learning outcomes vary by user.
