Documented cause
SeoulAI built Korean-language NLP tools for enterprise customers — sentiment analysis, document processing, and chatbot infrastructure. The company had 12 enterprise clients and ₩14B ARR. Then Kakao and Naver jointly announced HyperCLOVA, trained on 1B+ Korean documents. LG, Samsung, and SK all launched internal Korean LLM programs. Korean enterprise procurement shifted to chaebol-backed Korean AI rather than startup alternatives.
Lesson
“Korean NLP startups must build proprietary domain datasets in verticals the chaebols don't prioritize — legal, medical, or financial compliance data that Samsung and Kakao won't collect.”
