Tarifflo
Tarifflo is an AI-driven trade automation platform that classifies products under the Harmonized Tariff Schedule, files customs entries directly with CBP, and audits past import entries to recover overpaid duties. Founded in 2024 in Utah by ex-KPMG trade compliance specialist Bryce Judy and engineer Tanner Helms, it uses agentic AI to do work that traditionally required entire compliance teams and customs brokers, cutting hours of documentation to minutes. The company is a Y Combinator S26 startup.
Passage
Passage is an AI co-pilot for customs brokers and freight forwarders that automates the tedious paperwork of clearing imported goods. Founded in 2024 by former Google and Flexport engineers Terrell Marshall and Aditya Nadkarni, and backed by Y Combinator's S24 batch, the software reads commercial invoices, bills of lading, and packing lists, checks them for consistency, classifies products under HTSUS tariff codes, drafts filings, and handles routine email correspondence - work that entry writers otherwise do by hand for hours each day.
Pax
Pax is an AI-native customs broker that automates and maximizes U.S. tariff refunds through duty drawback - the CBP program that lets companies recover up to 99% of import duties on goods that are later re-exported, manufactured for export, or destroyed. Founded by MIT PhD Penny Chen and repeat founder Chris Le, Pax pitches itself as 'TurboTax for duty drawback,' using LLM-powered document extraction plus deterministic optimization algorithms to file audit-ready claims in weeks instead of the industry-standard 9-12 months, while recovering roughly 15% more than legacy providers. The company raised a $4.5M seed round in 2025 and is a Y Combinator Summer 2024 company.
Caspian
Caspian is an AI-native global trade advisory platform that helps importers and exporters recover unclaimed import duties and stay compliant as tariff rules shift. Founded in 2024 by ex-Flexport operators Justin Sherlock and Matt Ebeweber, the San Francisco company is a licensed US customs broker and CBP-approved software vendor. Its platform ingests shipping and inventory data to identify eligible duty drawback and refunds, then files the paperwork with US Customs in days rather than months - replacing the spreadsheet-and-email legacy process that leaves billions of dollars unclaimed every year.
