Blumen Systems

Blumen Systems is a San Francisco software company building an AI-powered operating system for infrastructure permitting and environmental diligence. It fuses 2,000+ geospatial datasets, a nationwide database of local zoning and permitting rules across 3,200+ jurisdictions, and a decade of historic permit outcomes to flag fatal flaws and regulatory risk on energy and infrastructure sites in days instead of months. In 2025 its tools were used to evaluate roughly 60 GW of solar, battery, gas, and data-center projects.
