Video Rebirth closes $80M round to build physics-bound AI video worlds
What's the deal? Singapore-based Video Rebirth has announced the final close of an $80 million funding round to build AI that generates hyper-realistic, physics-bound 3D worlds. The total combines an initial $50 million raised in late 2025 with a newly secured $30 million extension. The startup was founded by Dr. Wei Liu, a former Tencent distinguished scientist, and runs on a team of around 30 across Singapore and Hong Kong — tiny by AI-video standards.

Why it matters. The capital lands as Video Rebirth's flagship Bach model debuted at No. 6 on an Artificial Analysis text-to-video leaderboard — ahead of every other startup and behind only Alibaba, ByteDance, Kuaishou, and xAI. Bach is also the cheapest per minute of video among the top 10, and supports multi-shot videos up to 45 seconds, triple the 15-second cap of ByteDance's Seedance 2.0.
The signal. Video Rebirth's investor list reads like a roadmap for where world models could land — chipmaker AMD Ventures, carmaker Hyundai's ZER01NE, and Korean game developer Actoz Soft each map to one of the industries the company wants to disrupt, from autonomous driving to gaming. For a breakout-stage startup of just 30 people, securing that mix of strategic corporate backers signals these players see Video Rebirth's physics-bound approach as a credible bet against the likes of Google, Meta, and OpenAI. Training and running cutting-edge video models still costs tens of millions of dollars, and the company has said it plans to raise again.
