Nizzi Karai Renaud is a brand and marketing executive with a Master’s in Applied Positive Psychology, known for scaling iconic consumer businesses while keeping the work human, modern, and measurably effective. She is Chief Brand Officer at Zazzle, leading brand, growth, communications, PR, and policy at the intersection of commerce, technology, and human behavior. Prior to Zazzle, she held leadership roles at Etsy, Refinery29, and Atari, and has worked across tech, media, politics, and the nonprofit sector. This range gives her a rare view of how culture, trust, and incentives shape what people actually do. Nizzi brings a distinctive blend of commercial rigor and human-centered leadership. She is as comfortable with full-funnel performance and P&L realities as she is with the psychology of belonging, identity, and meaning that makes loyalty stick. Her work sits at the crossroads of brand strategy, marketplace trust, and ethical innovation, especially as AI changes how customers discover, decide, and relate to brands. She holds a Master’s in Applied Positive Psychology from the University of Pennsylvania, a Public Leadership Credential from Harvard Kennedy School, and a dual MA/BA in Integrated Marketing Communications from Emerson College.
