OPEF is an AI-native platform for environmental permitting and compliance, purpose-built for the environmental professionals who carry liability for the reports they sign.

Our system of record starts with the Phase I Environmental Site Assessment, structured around ASTM E1527-21. The platform pairs an anti-hallucination rulepack with a complete evidence graph, ensuring every finding is traceable to its underlying records and every conclusion is defensible.

The same foundation extends across NEPA review, MS4 and NPDES stormwater compliance, and FERC hydropower licensing. OPEF reduces turnaround time without compromising the accuracy and auditability these workflows demand.

Permitting is the #1 bottleneck on American infrastructure. We are building the software layer to fix it.
