Building the intelligence layer XR has been missing.

I build Spatial AI systems that don’t forget.
XR resets every session. Apps stay siloed. Intelligence never compounds.
OpenSpatialAI is the infrastructure layer that enables systems to perceive, reason, remember, and adapt.

Varun Kumar Siddaraju
XR + AI Researcher & Systems Thinker
I’m Varun Siddaraju — founder of VeeRuby Technologies, researcher, and the person building OpenSpatialAI. My work is about one problem: making XR systems actually understand what’s happening around them.
10 years of research and deployment across education, healthcare, and spatial computing. One published book on Mixed Reality (Apress). Now building the infrastructure to make Spatial AI real.
