Four Echelon is building Rowe 1.0, the spatial model API, and Four Cad, the product workspace for understanding point clouds, CAD geometry, images, maps, and sensor context.
Rowe 1.0
A multimodal large spatial model for point clouds, images, maps, sensor context, and real-world scene structure.
Four Cad
A browser workspace that ingests OBJ, STL, and point-cloud data, then returns fit checks, issues, measurements, and visual reasoning overlays.
Responses API
A developer API for structured spatial outputs: fit, stability, placement, prediction, action planning, reconstruction, and optimization.

Spatial data is becoming a first-class input for software, but most tools still treat geometry, imagery, and sensor streams as files to view instead of context to reason over.
3D data is everywhere
Phones, drones, factories, warehouses, robotics teams, and CAD workflows now produce spatial data by default.
Spatial workflows are still manual
Fit checks, clearance reviews, placement decisions, and scene comparisons still depend on slow inspection loops.
AI needs physical context
Models that understand structure, constraints, and object relationships can power software that acts in the real world.
Four Echelon turns spatial inputs into structured decisions: whether an object fits, where something should go, what changed between scenes, what may happen next, and what action a system should take.
Spatial Model Runtime
Rowe accepts spatial scenes, images, goals, and sensor readings, then returns typed outputs that applications can render or automate against.
CAD Reasoning Workbench
Four Cad turns uploaded geometry into spatial input, runs Rowe, and displays reasoning scenes, measurements, comparisons, and suggested changes.
Generated Operations Dashboards
The platform can connect to live data sources and generate monitoring, control, and analytics surfaces from real project structure.
