About Pax

Pax is the AI-native broker that automates and maximizes tariff refunds through duty drawback. We've helped enterprises recover millions in duties and manage their entire trade compliance operation from one platform. Each year, 80% of eligible refunds, equivalent to $15B, go unclaimed. Pax is the first AI-first broker that makes this process transparent and streamline while maximizing all duty saving opportunities. We are two technical founders: Penny got her PhD from MIT and, and was a former research scientist at Amazon & Flexport, where I encountered the problem firsthand. Chris is a second-time founder and former software engineer at Amazon, Brex, and TikTok.
