OpenAI Sprints. Google Grades Itself. Trump Threatens. Disney Pays.
San Francisco | December 12 Sam Altman's memo about Gemini 3 triggered a ten-day sprint to ship GPT-5.2.
A former AI researcher left his Munich lab to chase what he calls the "holy grail" of artificial intelligence. His startup just raised $13 million with barely more than a demo video. What convinced investors to bet big on something that doesn't exist yet?
đź’ˇ TL;DR - The 30 Seconds Version
đź’° Former Synthesia cofounder raised $13 million for SpAItial, which builds interactive 3D worlds from text prompts.
👥 His team includes ex-Google and Meta researchers who built 3D teleconferencing and text-to-3D systems.
🎮 The goal: let a 10-year-old create a video game in 10 minutes using text commands.
Matthias Niessner took a break from his AI lab at Technical University of Munich to solve what he calls the "holy grail" of AI models. His startup SpAItial raised $13 million to build AI that creates interactive 3D worlds from text prompts.
The seed round, led by Earlybird Venture Capital, is unusually large for a European startup with little more than a teaser video. But Niessner assembled a team that knows 3D AI. His cofounders include Ricardo Martin-Brualla from Google's 3D teleconferencing team and David Novotny, who led Meta's text-to-3D project for six years.
SpAItial faces competition from Odyssey, which raised $27 million, and World Labs, already valued over $1 billion. But Niessner thinks the real challenge isn't just creating 3D worlds—it's making them behave like reality. He wants virtual glasses to shatter properly and objects to react with physics accuracy.
The plan is to license the foundation model to developers who build specific applications. Video games seem obvious, but the technology could work for construction visualization and robot training.
