Pax

AI Broker for Import Tax Refunds

Pax uses AI to automate import tax refunds (aka duty drawback) for retailers and manufacturers. We launched 4 weeks ago and have ~$200K in contracts. Each year, 80% of eligible refunds—equivalent to $15B—go unclaimed. Pax is the first AI-powered broker helping brands under $50M reclaim 3-5% of their revenue. Our algorithms generate 15% more refunds than the industry leader and reduce processing time by 99% with AI. 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.

Problem

U.S. companies spend over $100 billion annually on import taxes. The good news is that Duty Drawback—a tax refund program—lets companies reclaim that cash! Astonishingly, $10 billion (80% of eligible refunds) goes unclaimed each year. Why? The process is a real headache.

Today, dealing with the government and customs brokerages takes months, as they take 10-20% of the refund and refuse to work on claims under $100k. As a result, only large enterprises file drawbacks, leaving smaller businesses out in the cold. With trade wars heating up, duty drawbacks are more important than ever—new rules like Tariff 301 include an additional 25%- 100% duty on $50 billion of Chinese goods. It’s time to make the process simple and accessible!

Solution

Pax creates a TurboTax-like experience, requiring no duty drawback expertise. Our product uses AI to handle the heavy lifting of collecting, extracting, and validating data and maximizes claim amounts with optimization algorithms. Pax democratizes duty drawback, enabling importers of all sizes to recover money that is rightfully theirs.

Using Pax, companies:

  • Save hundreds of hours dealing with manual data entry.
  • Reclaim millions of dollars spent on import duties.
  • Full in-suite dashboard and analytic reporting.

😀 Ask: If you or any companies you know import goods into the U.S. (e.g., retailers like Nike or manufacturers like Zero Motorcycles) or customs brokerages, we’d love to chat! Please reach us at founders@getpaxai.com!
