The Operator
Derek Rosenzweig has spent two decades building and scaling partnership channels at companies like Shopify, BigCommerce, Web.com, and Brightpearl. From designing Shopify's Global Scaled Partner Program (9-figure ARR, 180% YoY growth) to launching BigCommerce across APAC, he's been the operator in the seat.
At Shopify, he built the PE/Investor Partner Channel from zero, created portfolio company value creation playbooks, and managed holding company partnerships with WPP, Publicis, and Dentsu. He's closed $7M ACV franchise deals, launched in 6 countries, and consistently turned partner ecosystems into revenue engines.
Today, he brings that same operator intensity to early-stage companies through DER Ventures — helping founders build what he's built, faster and leaner.
