Background

About Sergio Venzor

With more than 25 years in the payments industry, I’m driven by a single purpose — turning data into smarter investment decisions that fuel sustainable growth. As Director of U.S. Return on Investment Optimization & Global Strategy at American Express, I lead the optimization of a $3.2B annual investment portfolio across Proprietary Card issuers. My work focuses on maximizing return on investment, advancing data-driven strategy, and ensuring every dollar deployed delivers measurable value to our cardmembers and shareholders. Over the years, I’ve built and led high-performing teams that bridge finance, analytics, and technology, delivering major enterprise wins — from negotiating strategic partnerships that cut acquisition costs by 30%, to migrating core investment ecosystems from SAS to Cornerstone ahead of schedule, accelerating the LUMI integration. I’m passionate about data transformation, cross-market optimization, and global strategy, always seeking ways to connect insights with action. Whether it’s designing new frameworks like the Card Member Value (CMV) model or guiding market-level investment planning, my goal is simple: to create clarity, efficiency, and measurable growth in every decision.
