Choi Dong-yeol brings a rare mix of engineering, corporate, and venture backgrounds—holding degrees in mechanical engineering and working at Samsung Electro-Mechanics and Samsung Electronics before moving into venture capital, where he built one of the earliest investment approaches that split AI into specific areas like NPUs, model compression, industrial AI, and hyper-personalization. He focuses on Series A and B deals to build long-term trust with founders, looks for industrial AI tied to Korea's manufacturing strengths in sectors like shipbuilding, steel, and semiconductors, and was named Stone Bridge Ventures' first-ever CIO in 2024 based on his track record with companies like SuaLab, Gaonchips, and OpenEdge Technology.

Notable Investments
Stone Bridge Ventures was built by solo founder Jake Seid, who ran a small pre-seed fund and put together custom deal-by-deal syndicates for each company instead of using a typical blind-pool VC structure, focusing on B2B SaaS and B2B marketplace founders. As the fund's sole founder, Seid backed 12 companies that went on to become unicorns and stays closely involved with founders through scale and exit rather than stepping back after writing a check.
