A New Challenger Emerges in the AI Arena

The AI startup landscape has a notable new entrant. According to industry sources, Dai Jifeng, a renowned associate professor from Tsinghua University's Department of Electronic Engineering, has founded a new company named Naive.ai. Rather than competing in the crowded field of foundational model development, the startup is strategically focusing on the post-training of open-source models and the development of sophisticated AI agent systems, positioning itself as a potential enabler for next-generation applications.

Massive Funding Round Signals Strong Conviction

What has captured significant attention is the scale of its recent funding. Reports indicate that Naive.ai has secured approximately $300 million in its latest investment round, valuing the company at around $800 million. While the specific list of investors remains undisclosed, it is understood that the round included participation from premier venture capital firms and major technology conglomerates, reflecting strong market confidence in the team's technical vision and expertise.

Founder's Stellar Profile Bridges Research and Industry

The founder, Professor Dai Jifeng, boasts an illustrious career that spans academia and industry. A leading figure in computer vision, his influential research includes seminal work on deformable convolutional networks and the multimodal foundation model InternVL, with his publications garnering over 50,000 citations. His professional journey is marked by key roles at elite institutions:

  • Former Principal Researcher at Microsoft Research Asia;
  • Former Executive Research Director at SenseTime;
  • Returned to Tsinghua University as an associate professor in 2022;
  • Previously served as a co-initiator at MiroMind, an AI company incubated by Shanda Interactive in 2025.

All-Star Team Combines Deep Expertise

Insiders describe Naive.ai's core team as a gathering of top-tier talent. It includes several key technical members from MiroMind, alongside co-founder Zhu Xizhou. Zhu holds a Ph.D. from a joint program between the University of Science and Technology of China and Microsoft Research Asia, and has previously held research positions at SenseTime and the Shanghai Artificial Intelligence Laboratory, bringing substantial experience in both algorithmic research and practical implementation. This blend of academic excellence and product-building capability is considered the company's greatest strength.

MiroMind ceased its operations in China earlier this year, leading to Dai's departure. His swift re-entry into entrepreneurship with a seasoned team and substantial capital backing introduces a new variable into the intensely competitive AI field. Analysts suggest that by avoiding the direct foundational model race and instead specializing in post-training and agent ecosystems, Naive.ai may be carving out a distinct and potentially more pragmatic niche. Its progress will be closely watched by the industry.
