NextFin News - Vast, a Beijing-based startup specializing in generative 3D modeling, has officially reached unicorn status following a fresh capital injection that values the company at over $1 billion. The funding round, which closed in late May 2026, was led by Alibaba Group and Hengxu Capital, marking a significant milestone for its 26-year-old founder, Simon Song, a Gen-Z entrepreneur who previously co-founded the AI unicorn MiniMax.
The capital raise comes as the global race for "world models"—AI systems capable of understanding and simulating the physical world in three dimensions—intensifies. Vast’s flagship platform, Tripo AI, allows users to generate high-fidelity 3D objects from simple text or image prompts in seconds. According to data from the Beijing AI Industry Investment Fund, which also participated in the round, Vast’s revenue growth has exceeded internal projections, driven by a dual-track commercial strategy that charges corporate clients on a project basis while offering individual subscriptions ranging from $20 to $140 per month.
Song, a lifelong gamer who dropped out of a doctoral program to pursue AI, represents a new wave of Chinese founders moving beyond the "wrapper" applications of the early LLM era. His ambition is to build a "TikTok for 3D content," a social platform where users can share and interact with AI-generated virtual environments. This vision places Vast in direct competition with established giants like Tencent Holdings, which recently open-sourced its own Hunyuan 3D world model, and Google’s DeepMind division.
The valuation surge reflects a broader shift in venture capital sentiment within China. While the initial frenzy around large language models (LLMs) has cooled, investors are now gravitating toward specialized "vertical" AI that offers clear utility in gaming, industrial design, and spatial computing. Primavera Capital Group, an early backer of Vast, significantly increased its stake in this round, signaling confidence in the startup’s ability to maintain a technical lead over open-source alternatives.
However, the path to dominance is fraught with technical and regulatory hurdles. Analysts at Orient Jiafu, a participant in the Series A, noted that while Vast currently holds a "state-of-the-art" (SOTA) position in 3D foundation models, the computational costs of generating complex 3D environments remain prohibitively high for mass-market social media applications. Furthermore, the startup must navigate increasingly stringent data security and content moderation rules governing generative AI in China, which could complicate the rollout of its planned user-generated content platform.
The success of Vast also highlights the growing influence of the "MiniMax mafia"—a group of former employees and founders from the early AI unicorn who are now seeding a second generation of startups. Song’s pedigree as a co-founder of MiniMax provided the necessary credibility to secure massive compute resources and top-tier engineering talent in a market where both are in short supply. As U.S. President Trump’s administration continues to tighten export controls on high-end semiconductors, Vast’s ability to optimize its models for domestic hardware will be a critical factor in its long-term survival.
Despite the optimism, some industry observers remain cautious. The 3D modeling sector has seen previous hype cycles, most notably during the "metaverse" craze of 2021, which failed to deliver sustainable consumer products. Whether Vast can translate its technical prowess into a daily-use consumer platform remains the central question for its new investors. For now, the company is focused on the launch of its first "world model" later this year, a move intended to bridge the gap between static 3D objects and dynamic, interactive virtual spaces.
