Pax helps retailers, manufacturers, and wholesalers get refunds when they pay tariffs. We’re building the control center for U.S. duty drawback—a $10B/year opportunity hiding in plain sight. We use AI and automation to recover tariffs paid by importers when goods are later exported, returned, or destroyed. Most companies don’t even realize they’re eligible. We make sure no dollar is left behind. Tariffs have been top of mind for everyone. Companies have gone from paying 25% to 145% tariffs.
