ByteDance sued him for RMB 8M — two years later, his World Model startup is valued at $200M. Capital markets gave the opposite verdict
TL;DR
Tian Keyu, the intern ByteDance sued for RMB 8M after he sabotaged model training, now runs a World Model startup valued at $200M — funded by Wuyuan Capital.
Tian Keyu, the ByteDance intern facing an 8-million-yuan lawsuit for sabotaging internal model-training tasks, has founded a startup in the World Model space now valued at roughly $200 million. The project is being incubated and backed by Wuyuan Capital partner Meng Xing, with total funding in the tens of millions of dollars.
Between June and July 2024, while interning on ByteDance's commercialization tech team, Tian — dissatisfied with team resource allocation — wrote and modified code to maliciously attack a research project's model-training tasks, causing resource waste. He was fired in August 2024, and after repeatedly denying his actions in public, ByteDance sued him in November 2024 for RMB 8 million.
The case isn't settled, and investors have already given a different answer. Wuyuan's move is unusual for the Chinese VC scene — a founder with active litigation is typically a red line. But World Model is the narrow doorway everyone from Meta to Google DeepMind to Fei-Fei Li's World Labs is trying to squeeze through, and someone who could write attack code against a training pipeline has objectively demonstrated deep infra understanding. Meng Xing has backed contentious projects before (Manus, Deepware). This is another one.
From intern to a $200M valuation in 24 months — the timeline itself is a signal that the Chinese AI talent shortage now outweighs résumé-cleanliness requirements. ByteDance has lost at least 15 senior technical staff to startups over the past two years; this one is the most dramatic.
Tian told media that his startup "has nothing to do with the lawsuit." ByteDance has not commented.
