Alchemize is an AI-native customs brokerage that automates brokerage workflows to deliver expert-level compliance at software speed. The platform reduces manual data entry, accelerates regulatory responses, and provides shipment visibility, addressing inefficiencies in legacy customs brokers. It was founded by Samuel Fu, a former Netflix software engineer, and Robert Hou, previously the second engineer at YC-backed Confido. Alchemize is based in San Francisco and is part of Y Combinator's Spring 2026 batch.
