Lexius

Lexius is a Y Combinator-backed company that aI for Corporate Security Cameras. The company participated in the Winter 2026 batch of Y Combinator.

Lexius turns existing security cameras into an AI security guard that detects, documents, and alerts incidents like shoplifting and slip-and-falls.

Millions of locations already have cameras but no intelligence. Replacing them costs $50K to $100K per site. Lexius upgrades every camera instantly, no rip and replace, no new hardware.

Real-world camera systems are messy, fragmented, and decades old, and AI breaks on low-quality CCTV.

Lexius was part of Y Combinator's Winter 2026 cohort, has a team of approximately 3 employees, and is actively operating.
