About Dagny Prieto

For two decades, I\'ve worked at the leading edge of consumer technology, using emerging methods to answer a fundamental question:\"How can we use technology to drive discovery?\" From pioneering content platforms to AI-powered personalization systems, I\'ve built products that connect millions of people with the content and experiences they\'re seeking.Over the past eight years at Amazon, I\'ve led the development of machine learning and generative AI systems that personalize experiences for 315MM+ Prime Video customers worldwide. I founded and scaled a native advertising business, pioneered my team\'s adoption of AI tools, and translated cutting-edge AI research into production systems that drive engagement and discovery at scaleBefore Amazon, I built the unified content platform that served 300MM monthly users across Time Inc.\'s 24 brands—moving from legacy systems to a modern architecture that enabled automated content sharing and distribution at scale. Whether through recommendation algorithms, advertising platforms, or content infrastructure, I\'ve consistently focused on using technology to surface what matters most to users.What I\'m looking for: Executive roles where AI/ML strategy intersects with consumer experience—particularly in entertainment, media, education, and the arts. I\'m drawn to companies using technology to expand access to culture, learning, and storytelling.My approach: I lead by setting an achievable and inspiring vision, pioneering new methodologies (especially AI adoption), and building bridges between research, engineering, and business teams. I\'ve managed teams of senior technical PMs and led cross-functional teams across product, engineering, design, and data science.Let\'s connect if you\'re building products that help people discover what they\'re looking for.
