Izzy Rosenzweig is the founder and CEO of Portless, a direct fulfillment company that ships millions of ecommerce orders a year directly from manufacturers in China and Vietnam to consumers in 75+ countries in 5–8 days — with no domestic warehouse in the loop. Hundreds of fast-growing DTC and Shopify brands run on the model. Izzy comes from three generations in apparel manufacturing. His grandfather, a Holocaust survivor, built a Canadian dress manufacturing business that outlived hundreds of competitors through the 1980s container revolution. Izzy ran his own DTC brand before founding Portless and today runs teams across North America and Asia daily, a perspective most Western operators don't have. He brings a contrarian, operator-level point of view to ecommerce supply chain. Most founders in this space hedge on tariffs, China, the future of fulfillment, and the reshoring narrative. Izzy doesn't. He's good in long-form, hosts his own supply chain podcast, and engages with sharp questions instead of dodging them. Topics he can speak to: • Direct fulfillment and the model replacing the legacy 3PL • The cash conversion cycle as a hidden growth lever for DTC and Shopify brands • What most Western operators get wrong about manufacturing and managing teams in Asia • The onshoring trap — why "Made in America" is mostly marketing for most product categories • Cross-border ecommerce, tariffs, IEEPA refunds, and the shifting de minimis landscape • Lessons from three generations of manufacturing on which businesses survive industry disruption Izzy is based in Toronto, Canada available for remote interviews, and comfortable in long-form conversation.
