Hojun Choi left Goldman Sachs to build the AI tool that Goldman Sachs — and 170+ other institutional clients — now uses to research investments. At 29, the co-founder and CEO of LinqAlpha has built an AI platform that outperformed Nvidia, Google, and OpenAI in search precision for financial research, according to the company's benchmarks. LinqAlpha's multi-agent AI system automates the most time-intensive parts of hedge fund research: stock screening, company primers, peer comparisons, catalyst identification, and devil's advocate analysis — pulling from securities filings, financial reports, earnings transcripts, news, and alternative data across 60,000+ companies in 80+ markets in 20 languages. For hedge fund analysts accustomed to spending days compiling a single primer, LinqAlpha compresses the work to minutes. Choi co-founded the company with MIT PhDs, went through Techstars Boston in 2023, and raised $6.6 million in seed funding from Korean venture firms including Atinum, Intervest, and Smilegate Investment. The client roster grew from zero to 170+ global institutions — including Samsung Financial Network, KPMG, and numerous hedge funds — in under two years. Named to Forbes 30 Under 30 Asia in 2023, featured in TechCrunch, and published in ACL (the premier computational linguistics conference), Choi operates at the intersection of AI research and practical financial infrastructure. He's not managing a portfolio — he's building the tools that portfolio managers depend on. For this list, Choi represents a different kind of under-the-radar impact: not the person making the investment calls, but the person whose technology enables better calls at scale. In a world where AI is simultaneously the most hyped and most poorly understood force in finance, Choi is one of the few people actually building the infrastructure that works — and doing it from Seoul, not Sand Hill Road.
