Years-long decline before final shutdown · Fatal mistake: South Korea fintech: Kakao Pay (40M+ users, Kakao Bank IPO 2021) dominated. Toss (Viva Republica, $7.4B valuation, 18M+) was second. Naver Pay (20M+ users) was third. KB Kookmin Bank, Shinhan launched digital banking. FSC required full banking or e-money license. The "big three" Korean fintech (Kakao, Toss, Naver) held 78M+ combined users in 52M population.
Evaluating only SouthKoreaFin’s profile at its peak — without knowing the outcome — the model ranked Competition as the #1 likely cause. That’s exactly how it died.

Documented cause
SouthKoreaFin built fintech in Busan. Kakao Pay 40M + Toss 18M + Naver Pay 20M = 78M+ users. 52M population. No viable gap for 4th entrant.
Lesson
“South Korea fintech must target cross-border POSCO/Samsung/Hyundai supply chain payment corridors — Kakao/Toss/Naver serve domestic Korean consumer payments, but the global supply chain payment needs of Korean conglomerates are served by Swift and correspondent banking without fintech optimization.”
