Nucleus4D Raises $1.5M to Scale Spatial Capture Platform for Real-World Digitization

• Antler, South Loop Ventures, and sector-focused angels backed the pre-seed round.
• Founded by former Meta and Verizon engineers, Nucleus4D creates interactive digital twins from real-world spaces using AI and 3D Gaussian splatting.

Nucleus4D has raised $1.5 million in pre-seed funding to expand its spatial computing platform for digitizing real-world environments. The round was led by Antler and South Loop Ventures, with additional backing from angel investors in real estate, immersive media, and related sectors.

Co-founded by Navjeet Chhina, Paulin Byusa (ex-Meta), and Miran Brajsa (ex-Verizon), the company says it built Nucleus4D to replace complex, manual capture workflows with a single pipeline that produces everything from immersive tours to structured spatial data. The system uses one on-site scan to generate high-fidelity digital twins through a combination of 3D Gaussian splatting and AI reconstruction.

Since launching in Q3 2025, the company says it has processed over 25 million square feet of space and became the first 3DGS company approved to list immersive experiences on a major real estate platform. The new funding is expected to be used to support team expansion, infrastructure scale-up, and continued development of the company’s web viewer, collaboration tools, and spatial data engine.

🌀 Tom’s Take:

Nucleus4D isn’t just offering tours. It positions itself as spatial infrastructure, turning one capture into reusable data for both humans and machines.
