Honest ECommerce | Bonus Episode: Tweaking Tariffs to Maximize Margins Legally with Izzy Rosenzweig

Izzy Rosenzweig is the founder and CEO of Portless, a supply chain platform helping ecommerce and DTC brands fulfill customer orders directly from China, cutting delivery times and unlocking cash flow through tax deferment and tariff optimization.
A 10-year DTC veteran, Izzy first launched Browze in 2012, shipping over 2.5 million home and kitchen products globally. After building a China-based fulfillment center to improve customer experience, he saw an opportunity to help other brands bypass traditional U.S. warehouses, leading to the creation of Portless.
Portless enables brands to ship faster, avoid upfront taxes, and reclaim working capital, transforming how modern operators manage logistics. Izzy’s deep experience in cross-border fulfillment, HS code strategy, and tariff engineering gives him a unique lens into how ecommerce brands can survive regulatory shifts and thrive under pressure.
With a margin-first, speed-to-cash mindset, Izzy helps brands reimagine global operations to win in today’s volatile landscape, efficiently, legally, and profitably.
