The Observed-World Layer, for Physical AI
Continuous, structured, privacy-disciplined annotation of public space, delivered as an ingredient to the companies building physical AI.
AI models have barely seen the world.They've glimpsed it in scattered photographs, video clips and text. They're missing a continuous record of how physical spaces actually behave hour to hour. 375ai built the infrastructure that produces that record.
Outfront Media Partnership
A nationwide partnership with OUTFRONT Media (NYSE: OUT) puts 375ai nodes across 40,000 premium public-space locations.
Millions of Data Points
Structured data comes off every node continuously — counts, classifications, movement. The annotations that make raw footage useful, produced in real time, around the clock.
On-device Inference
Every node runs AI inference at the edge, turning live video, audio, and environmental signals into structured output before anything leaves the device.
An ingredient, not an application. 375ai is the observed-world data layer. Our customers build the models, the robots, the vehicles. We build what they learn from.
All roads lead to the same place. AI models are starved for high fidelity annotated real world data.
The mission: to give physical AI its ground truth, turning how cities move into continuous, structured, privacy disciplined data.
