Sung Kim (김성훈), known professionally as Hun Kim, is the Co-Founder and CEO of Upstage AI, South Korea's first generative AI unicorn. A former HKUST professor and founding head of Naver Clova AI, he co-founded Upstage in October 2020 to solve the gap between enterprise data and practical AI deployment. Under his leadership, Upstage developed Solar - a compact 10.7B parameter language model - and Solar Pro 2, which outperforms GPT-4.1 at half the compute cost. With $326M in total funding and a Series C close in early 2026, Upstage is positioning itself as a global AI frontier company focused on enterprise document intelligence and AI agents.
