What Stone Bridge Ventures does
Stone Bridge Ventures Corporation (스톤브릿지벤처스 주식회사) is a publicly listed South Korean venture capital firm (KOSDAQ: 330730) founded in 2010 and headquartered in the Gangnam district of Seoul at Teheran-ro 211, KFAS Building 14F. The firm invests in technology and life science companies across all stages from seed through late-stage, with a stated focus on entrepreneurs whose innovations can expand individual lives, industries, and markets. Since inception, Stone Bridge has accumulated investments in 231 portfolio companies spanning sports technology, space infrastructure, software security, biotech drug delivery, autonomous driving, physical AI, and medical devices (e.g., Plco/QMIT, Intergravity, Labrador Labs, Inventage Lab, Mobiltech, Livsmed). The firm operates under the Korean Stewardship Code with documented governance and engagement principles, and its core technology is the venture investment platform itself rather than a licensed software product.
Stone Bridge generates revenue through two primary streams: (1) recurring management fees on assets under management (107 billion KRW in 2021), and (2) carried interest from successful fund exits (141 billion KRW in 2021, a 3x year-over-year increase). The firm reported 422 billion KRW in revenue and 272 billion KRW in operating profit in 2021, up 72.1% and 84.9% YoY respectively. Cumulative AUM reached 13,146 billion KRW across 14 venture funds and 5 PEFs, with ten funds fully liquidated delivering a 2.8x Multiple and 27.0% IRR over a recent three-year window and 5,416 billion KRW distributed back to investors. Key limited partners include IBK Industrial Bank (co-GP on multiple PEFs), National Pension Service, Korea Venture Capital, POSCO, and Shinhan Capital, with the Stonebridge DX Business Restructuring Fund and IBK-Stonebridge New Deal ESG Unicorn PEF each exceeding 1.6 trillion KRW.
The firm is led by CEO Yoo Seung-woon (유승운), formerly of Kakao Ventures and SoftBank Ventures Asia, with Vice Chairman Kim Ji-hoon (김지훈) holding an MIT Sloan MBA. Other senior leaders include CIO Choi Dong-yeol (최동열), CFO Bae Young-soo (배영수), and compliance/legal head Kim Jong-hyun (김종현). The firm has entered a full-fledged exit cycle with multiple IPO candidates in its portfolio (Nearthlab, Madup, Allganize, Ingenia Therapeutics, NexEye) and launched its first dedicated AI fund in 2026, securing over 200 billion KRW in commitments within six months. A leadership signal to monitor is the announced June 2026 departure of senior investment manager Son Ho-jun, attributed to portfolio underperformance.
