Born in 1997 in Hangzhou, he studied philosophy and Middle East politics at Johns Hopkins, worked in the CEO's office at SenseTime, and co-founded the Chinese AI unicorn MiniMax before starting VAST in 2023 shortly after Google's DreamFusion showed text-to-3D was possible. A self-described gamer and anime fan, Song wants to let anyone create 3D content with zero barriers and zero cost, and has grown Tripo Studio past 6.5 million users with clients including Tencent, Sony, Microsoft and Pop Mart.
Tripo AI
Tripo AI, built by the startup VAST, is a generative-AI platform that turns text prompts and images into production-ready 3D models in seconds. Its Tripo Studio app and REST API cover the full 3D pipeline - generation, texturing, rigging, retopology, segmentation and stylization - and are used by more than 6.5 million creators and roughly 90,000 developers. Founded in 2023 by former MiniMax co-founder Simon Song, the company is pushing from single 3D assets toward interactive, persistent 'world models' and has raised close to $400 million from backers including Alibaba and Baidu Ventures.
