About the author
Izzy Rosenzweig is the founder and CEO of Portless, the modern e-commerce supply chain. A 10-year direct-to-consumer veteran, Izzy built his career solving the fulfillment problems that slow brands down — long inventory lead times, trapped cash flow, and the compliance headaches of shipping across borders. That hands-on experience became the foundation for Portless, which helps brands ship direct from origin, cut inventory lead times from months to days, and free up cash flow along the way. Izzy writes about cross-border fulfillment, tariffs, and the regulatory shifts reshaping global commerce, with a focus on how modern operators build supply chains that hold up under pressure. Follow along for his take on tariffs, cross-border fulfillment, and the future of how brands move product.
