Lexius transforms existing corporate security cameras into AI-powered security systems that detect and document incidents such as shoplifting and slip-and-falls, then alert users. Rather than requiring expensive hardware replacement, which the company estimates at $50K-$100K per site, Lexius upgrades current camera systems instantly with no new equipment. The company aims to become the operating system for physical spaces, beginning with security and liability solutions. Lexius is part of Y Combinator's Winter 2026 batch.
