SpAItial

SpAItial is a company building what it calls spatial foundation models, AI systems that generate and reconstruct photorealistic, physically grounded 3D environments. The company launched in May 2025 with a $13 million seed round, with Jon Barron, one of the creators of NeRF, among its angel investors.

Echo, its first public model, arrived in December 2025 and turns a single image or text prompt into a navigable, metric-scale scene that SpAItial's web demos render as Gaussian splats in the browser. Echo-2 followed in April 2026, adding semantic segmentation for object-level editing, virtual staging, full-scene style transfer and walkthroughs generated from 2D floor plans. SpAItial reports that Echo-2 outperforms World Labs' Marble 1.1 on the WorldScore benchmark.

Echo-3, released on October 27, 2026, takes the company from generation into capture. A companion iPhone app records a few minutes of footage, and Echo-3 turns it into a photorealistic Gaussian splat scene at real-world scale, filling in regions the capture missed. Scenes can be explored, measured and shared through a browser link, and an Android version is listed as coming soon. According to SpAItial, Echo-3 exports SPZ and SOG splats along with meshes, normals and depth.

Developers reach the models through the SpAItial Developer API. In June 2026 the company shipped a Claude plugin and a hosted MCP server that generate, edit and export worlds from inside a chat, and the same remote endpoint works across Claude Code, Cursor, VS Code and other MCP clients. Enterprise API access to Echo-3 is arranged through the company's partnerships team.

The capture app is priced in credits, at 300 credits per scan minute. The Standard plan includes 7,500 credits a month, or 25 scan minutes, for non-commercial use, and the Pro plan includes 15,000 credits, or 50 scan minutes, with commercial rights. A one-month free trial is available. Reconstruction runs in SpAItial's cloud and generation runs through its hosted service, so no local GPU is required.
