Empirium is a vetted marketplace connecting buyers and sellers across the U.S. defense industrial base (DIB). The platform is designed to help organizations source compliant products and reach verified customers without middlemen or transaction fees. Its listings include parts for unmanned systems, power systems, sensing equipment, electronics, peripherals, materials, complete platforms and kits, machinery, spares, services, and manufacturing from DFARS-compliant job shops.

U.S. buyers can search by part number, description, capability, or geography; contact sellers directly; send requests for quotes and purchase orders; compare offers; and track shipping in one conversation thread. They can also organize components into projects and purchase supply chain audit reports, including reports for individual items or bills of materials. Buyer access is free, with unlimited users.

Sellers can create a storefront and publish unlimited listings at no charge after verification. A monthly subscription lets U.S. sellers respond to buyer messages and quote and invoice orders. Empirium verifies businesses and screens them against sanctions lists. The company also works with allied sellers on membership terms.
