From quantitative private equity to AI large models, Liang Wenfeng's cross-industry business insights

【BlockBeats】An interesting data point worth noting: the so-called domestic quant private equity giant, Fantasia Quantitative, has achieved a return of 56.55% so far in 2025, ranking second among private equity firms with billions in assets, only behind Lingjun Investment with a return of 73.51%. The mastermind behind this is Liang Wenfeng, who is also the founder of the recently trending AI company DeepSeek.

Fantasia Quantitative now manages over 70 billion yuan. Even more impressive are its past performance records: an average return of 85.15% over the past three years and 114.35% over the past five years. This stable high return has made Liang Wenfeng a major supporter of AI development. Industry analysts believe that it is Fantasia Quantitative’s sustained hefty profits that provide sufficient funding for DeepSeek’s R&D.

Looking at his background, Liang Wenfeng founded Fantasia Quantitative in 2008 while studying Information and Communication Engineering at Zhejiang University. The company combines mathematics, computing, research, and AI genes. It surpassed 10 billion yuan in assets under management in 2019 and once broke through 100 billion yuan in 2021. Now, this hedge fund has become an invisible driver in the AI field.

The latest news is that DeepSeek plans to release its new flagship AI model V4 in February, which claims to have powerful programming capabilities and may impact the current AI competitive landscape. It seems that the high returns from quantitative trading and the technological breakthroughs of AI models have created an interesting closed loop for Liang Wenfeng.
