XtalPi Holdings LimitedXtalPi co-led Apex Intelligence's angel round, investing in the self-evolving AI startup.

Beijing-based Apex Intelligence has completed its angel and angel-plus funding rounds, raising nearly US$50 Million in total. The angel round was co-led by IDG Capital, LinkX Capital and XtalPi, with participation from Decent Capital, SEE Fund, Monad Ventures, and Winsoul Capital, while the angel-plus round was co-led by Zhongguancun Science City Fund, SCGC, and Shanghai Engine Fund. Founded in June 2026, the company is building self-evolving foundation models based on Recursive Self-Improvement, or RSI, aiming to move AI from an assistive tool to a co-researcher focused on scientific research and discovery. Apex Intelligence said its self-evolving AI system has autonomously produced research of a standard suitable for acceptance at leading AI conferences, comparable to an AI PhD student, and has set new records or approached the best publicly reported results across SimpleTES, NanoChat Autoresearch, GPUMode TriMul, and MLS-Bench, outperforming solutions developed by or with contributions from Recursive Superintelligence, Tencent Hunyuan, Stanford, NVIDIA, and other organizations. The system also produced a complete proof of the majorization conjecture, which had remained open for more than three decades, and achieved multiple breakthroughs in optimization theory and geometric topology. The company was founded by Yongchao Chen, an assistant professor at Tsinghua University's School of Artificial Intelligence, and will visit leading North American universities including Harvard University, MIT, Yale University, and Boston University from September 17 to September 23 for talent recruitment and research collaboration.
