From Hedge Fund to Frontier AI: The Unconventional Rise of Liang Wenfeng and DeepSeek

Who is Liang Wenfeng? This episode explores the remarkable journey of Liang Wenfeng, a Chinese engineer who disrupted the global tech landscape with his A.I. company, DeepSeek. DeepSeek's emergence was unconventional, lacking state backing, big-name alliances, or the institutional heft of other players in China. The episode delves into Liang's leadership style, which emphasizes intellectual exploration and collaboration, even including literature buffs on the engineering teams. Sources: WSJ and NY Times More Early Life and Education: Liang Wenfeng was born in 1985 in Zhanjiang, a port city in southern China. He demonstrated an aptitude for math early on, and was a math geek. He attended China's prestigious Zhejiang University. His 2010 thesis at Zhejiang University focused on improving intelligent tracking algorithms for surveillance cameras, a topic that would become prominent in Chinese AI. Transition to Finance and AI: • Liang's career path took an interesting turn when he caught the investing bug. He began writing AI algorithms to pick stocks while he was a student. • In 2013, he started an investment firm called Jacobi, named after the German mathematician Carl Jacobi. • In 2015, he co-founded High-Flyer with two college friends. • High-Flyer was a pioneer in China for applying AI techniques to analyze diverse data sets, not just market prices, and identify significant patterns. • Liang drew inspiration from Jim Simons, a mathematician and pioneer in quantitative finance who used machine-learning techniques in the 1980s. Liang even wrote the introduction to the Chinese version of a book about Simons, noting that he recalls Simons’ words, “There must be a way to model prices,” when facing difficulties. • High-Flyer managed about $8 billion, becoming one of China's largest quantitative funds. Over five years, several of High-Flyer's funds produced average excess returns of more than 20% compared to market benchmarks. • High-Flyer experienced setbacks from regulatory crackdowns on quantitative trading in 2023. Shift to AI Research: • Liang pivoted from finance to AI research in 2023. • He was wary of Beijing’s tightening grip on speculative trading, and he poured his own money into AI, specifically A.I. chips, and assembled a team to build China's answer to Silicon Valley front-runner OpenAI. • DeepSeek was initially a side project within his hedge fund, starting in 2019, to give the company's PhDs something to do, but it became the main focus after the hedge fund's primary investment product was shut down in 2024. • Liang's primary ambition is to create artificial general intelligence (AGI), which he sees as China's real chance to catch up with the United States. Liang's Leadership Philosophy: • Liang is described as a deeply technical engineer, not one for the trappings of wealth or fame. He prefers to be thought of as an engineer rather than a trader. • He is a hands-on leader who refines algorithms and works closely with his team, sometimes sleeping in the office to get projects done. • Liang's approach emphasizes intellectual exploration and a bottom-up structure, rather than a focus on grinding hours. • He believes innovation starts with confidence, which he sees more in young people. • His hiring philosophy values passion, curiosity, and diverse backgrounds, including the hiring of literature majors to help refine AI models. • He is willing to try things that other entrepreneurs will not. • His decision to make DeepSeek's code open-source was intended to break the monopoly of big tech companies. • He believes that being followed is rewarding for technologists and that open-source is a cultural act, not just commercial. DeepSeek's Position: • DeepSeek's emergence as a disruptive force was unexpected. • Liang's focus is on research, not on quick commercial applications. • He aims to establish an ecosystem where others build applications on DeepSeek’s foundational models, while his team focuses on research.
