YCurb builds digital curb infrastructure for cities — a software platform that digitizes curb assets, rules and activity into a single management layer for parking, loading, permits, enforcement and emerging mobility. Its GPS-based curb usage tracking converts disparate curb data sources into the uniform Curb Data Specification (CDS) standard and builds a digital twin of the curb. The company describes itself as a curb operating system for public agencies rather than a parking service, and is designed to deploy without new hardware or replacing existing systems. It has worked on municipal curb pilots including the City of San José, in partnership with Blue Systems.
