    • Co-build programs for high-volume, multi-team deployment

INVESTORS

Infrastructure for a $50B+ permitting market.

Environmental permitting is a mandatory step in every major infrastructure project in the United States. OPEF is building the system of record that makes that process traceable, defensible, and fast.

  1. 01
    Durable regulatory demand

    Federal environmental review is statutory — NEPA, ESA, Clean Water Act, and dozens of related programs are not optional, and project counts are growing as infrastructure spending increases.

  2. 02
    System-of-record positioning

    Permitting teams produce administrative records that must hold up to legal challenge; the platform that structures and stores those records becomes deeply embedded in agency and consulting workflows.

  3. 03
    AI that compounds over time

    Every completed review adds structured precedent — rulepacks, citations, and reviewer decisions — that raises accuracy and reduces review time for every subsequent project on the platform.
