Teresa Barreira

Hello, my name is Teresa Barreira. I'm a transformational leader and innovator redefining modern marketing. As the Chief Marketing & Communications Officer at Publicis Sapient, I have reinvented the brand and repositioned the company as a leader in AI-led digital business transformation. My creative and bold thinking, along with over 25 years of global B2B marketing expertise, has enabled me to break the mold of traditional marketing in the technology and IT services industry. I'm at the forefront of marketing innovation, leveraging AI to reimagine the marketing function for a future that is highly agentic and dynamic—introducing an agentic content supply chain, augmenting creative intelligence, and creating teams where humans and AI agents collaborate seamlessly. Prior to joining Publicis Sapient, I served as CMO of Deloitte Consulting and also held senior leadership roles at IBM, Accenture, and high-growth software startups.
