Junho Lee worked at a Samsung Care center in Hongdae for 3 years, earning ₩3,000,000 per month. He performed 15–20 Galaxy repairs per day — efficient, accurate, professional. The care center charged ₩150,000–₩350,000 per repair. His take: ₩3,000,000 monthly salary.
"I was earning ₩3 million a month doing ₩100 million worth of work for Samsung," he says. "That is the whole story."
The Decision
In 2024, Junho used ₩22,000,000 in savings to open a shop in Mapo — one of Seoul's growing residential and creative districts, popular with young professionals, media workers, and independent business owners.
He set up RepairCoreX before signing his shopfront lease.
"Korean professionals are meticulous," he says. "They check Naver reviews. They check Kakao Maps. They expect 사업자등록번호 on the invoice. They expect a warranty certificate. RepairCoreX gave me all of this from my first customer."
The First Month
Junho opened quietly — no grand launch. His first customers came from Naver blog searches for repair shops near Mapo-gu.
Month 1: ₩78,000,000 revenue.
"That number shocked me," he says. "I had worked for Samsung for 3 years and earned ₩3 million per month. My first month on my own: 26 times more revenue."
The difference was not skill — it was ownership, system, and location. The same hands. Completely different economics.
KakaoTalk Integration
Junho used RepairCoreX's notification system to send status updates via KakaoTalk — Korea's primary messaging platform. Customers who received a KakaoTalk notification saying their Galaxy S24 Ultra screen was ready told their friends about "the professional shop in Mapo that sends KakaoTalk updates."
Within 90 days, Junho had 180+ five-star Naver reviews.
Today
Junho earns ₩25,000,000–₩28,000,000 monthly net. He employs 2 technicians and a front desk staff. He has two K-entertainment production companies as regular corporate clients.
"한국은 전문 수리 서비스를 필요로 합니다," he says. "The market is waiting for professionals. RepairCoreX is the system. Start today."
