Nucleus4D raises $1.5M pre-seed to digitize the built world

Nucleus4D sits at an important junction between computer vision, 3D graphics and AI. By using 3D Gaussian Splatting to turn physical locations into high‑fidelity, interactive digital twins from a single capture, it is effectively building a spatial data layer that can feed both human experiences and machine learning pipelines. As labs like AMI, World Labs and the big hyperscalers chase world models that understand the physical environment, high‑quality, scalable capture of the built world becomes strategic infrastructure, not just a real‑estate marketing tool.

The $1.5 million pre‑seed is small in absolute terms but telling: early‑stage capital is now flowing into companies whose main value proposition is generating structured 3D data for future physical AI systems. If Nucleus4D can maintain quality while scaling to millions of spaces, its dataset and pipelines could become highly attractive to robotics, AR and simulation players that lack their own capture stack. For the race to AGI, the broader story is that we are starting to industrialize the collection of training data for embodied and world‑model systems, moving beyond scraped web text toward dense, photorealistic representations of the real world.
