Liang Wenfeng

Liang Wenfeng (Chinese: 梁文锋; pinyin: Liáng Wénfēng; born 1985) is a Chinese entrepreneur and businessman who is the founder and CEO of DeepSeek, an artificial intelligence company that shocked global markets in January 2025 when its AI model surpassed ChatGPT to become the number one free app on the US App Store.

DeepSeek's breakthrough demonstrated that competitive large language models could be built at a fraction of the cost of Western competitors, triggering a $1 trillion market capitalization wipeout in US technology stocks. Liang is also co-founder of High-Flyer Quantitative Investment, one of China's largest hedge funds, which he used to fund DeepSeek's development when venture capital firms were reluctant to invest.

Early life and education

Liang Wenfeng was born in 1985 in the village of Mililing, Tanba town, Wuchuan city, in Guangdong province, southern China. His parents were both primary school teachers.

Residents of his hometown told the Financial Times that as a child he was a "top student" who read comic books and excelled in mathematics.

Liang attended Zhejiang University in Hangzhou, one of China's elite universities. He received a Bachelor of Engineering in electronic information engineering in 2007 and a Master of Engineering in information and communication engineering in 2010. His master's dissertation was titled "Study on object tracking algorithm based on low-cost PTZ camera."

Career

Quantitative finance: High-Flyer

During the 2008 global financial crisis, Liang formed a team with his university classmates to accumulate data related to financial markets, recognizing the opportunity to apply quantitative methods to investing.

In 2016, Liang co-founded Ningbo High-Flyer Quantitative Investment, a hedge fund that utilized AI and mathematical models for investment decisions. The firm grew rapidly:

• 2019: Over 10 billion yuan ($1.4 billion) in assets under management
• 2021: Exceeded 100 billion yuan (approximately $14 billion) in assets under management, making it one of China's largest quant hedge funds

The success of High-Flyer provided Liang with the resources and AI expertise that would later enable DeepSeek's development.

Founding DeepSeek

In May 2023, Liang announced that High-Flyer would pursue the development of artificial general intelligence (AGI) and launched DeepSeek.

In an interview with 36Kr that month, Liang revealed that High-Flyer had acquired 10,000 Nvidia A100 GPUs before the US government imposed AI chip restrictions on China. This hardware stockpile laid the foundation for DeepSeek to operate as a large language model (LLM) developer despite US export controls.

DeepSeek receives funding from High-Flyer. Liang chose this unconventional funding route because venture capital firms were reluctant to invest, viewing the project as unlikely to generate returns in a short period of time. Given the long-term nature of the goal, Liang sought employees who had ability and passion rather than extensive experience.

As of May 2024, Liang personally held an 84% stake in DeepSeek through two shell corporations.

DeepSeek's breakthrough

On January 20, 2025, DeepSeek released DeepSeek-R1, a 671-billion-parameter open-source reasoning AI model. The model was remarkable for its efficiency: it was built using just 2,048 Nvidia H800 GPUs at a reported cost of only $5.6 million—a fraction of the billion-dollar budgets of Western competitors like OpenAI.

By January 27, 2025, DeepSeek surpassed ChatGPT to become the number one free app on the United States iOS App Store. The news triggered panic in US markets, with more than $1 trillion erased from technology stock market capitalizations in a single day as investors reassessed assumptions about AI development costs and competitive advantages.

Recognition and government relationships

Meeting with Chinese leadership

On January 20, 2025—the same day DeepSeek-R1 was released—Liang was invited to a symposium hosted by Chinese Premier Li Qiang in Beijing. As an industry expert, he was asked to provide opinions and suggestions on a draft of the annual 2024 government work report.

On February 17, 2025, Liang was invited to a symposium with private-sector enterprises hosted by General Secretary Xi Jinping at the Great Hall of the People in Beijing. The invitation signaled the Chinese government's recognition of DeepSeek's strategic importance.

Philosophy on innovation

Liang has articulated a vision for China's role in global innovation. He stated that as China's economy develops, it should "gradually become a contributor instead of freeriding." He has argued that what is lacking in China's innovation is "not capital but a lack of confidence and knowledge on organizing talent into it."

Personal life

Liang maintains a private personal life. Details about his marital status and family are not publicly disclosed.

According to Forbes, he is now worth at least $1 billion following DeepSeek's breakthrough.

Controversies

US-China AI competition

DeepSeek's success has intensified debates about US-China technological competition and the effectiveness of American export controls on advanced semiconductors to China. Critics have questioned whether the restrictions are achieving their intended goals, given that DeepSeek demonstrated competitive AI capabilities using older, legally available chips.

National security concerns

Some US policymakers and security analysts have raised concerns about the implications of a Chinese AI company achieving parity with American models, particularly regarding potential applications in surveillance, military, and information warfare.

Open source approach

DeepSeek's decision to release its models as open-source has generated debate. Proponents argue it advances global AI development and transparency, while critics worry about enabling misuse of powerful AI capabilities.
