AGI Accelerates Its Global Client-Centric Transformation with Appointment of Matt Nitzberg as Chief Client Officer
Toronto, ON — January 19, 2026 — Advantage Group International (AGI) today announced the appointment of Matt Nitzberg as Chief Client Officer, underscoring the company’s dedication to deepening client relationships. In this role, Nitzberg will lead all global client service, sales, marketing, and commercial activities, bringing AGI’s client-facing teams together under a unified mandate.
Alongside his new global mandate, Nitzberg will continue to serve as Head of North America, maintaining close connection to one of AGI’s fastest-growing markets while extending proven approaches to developing client partnership across the broader organization.
The appointment represents a key building block as AGI cements its role as the most trusted source of B2B relationship insight, which is also supported by a revolutionary Always-On model of client engagement, beginning in 2026 with the launch of Advantage LiveLensTM. By unifying commercial and client-facing teams under a single leadership structure, AGI is strengthening how it brings innovation to market and supports complex B2B relationships to deliver more impact for clients.
“Matt’s appointment reflects how we are evolving AGI for the future,” said Peter Harris, CEO of Advantage Group International. “Over the past three years, he has strengthened client partnerships and delivered disciplined growth in North America. Bringing our global client and commercial teams together under his leadership allows us to scale those outcomes, improve consistency across markets, and deepen the value we deliver to clients worldwide.”
Nitzberg’s background positions him well to lead this unified global client organization. He brings more than three decades of experience leading client, commercial, and growth organizations across data-, insight-, and technology-driven businesses. His background includes senior leadership roles at leading analytics and insight firms such as dunnhumby and Circana, where he led client strategy, commercial development, and large-scale transformation initiatives. Most recently, he led AGI’s North American business through a period of sustained growth, advancing client partnerships and client-led product innovation developed in close partnership with leading suppliers and retailers.
“Having worked with Matt across several organizations in our careers, I’m excited to see his elevation within AGI,” said Marty Thompson, CEO of Nestlé USA. “Strong customer engagement is a top priority for Nestlé on a global basis, and I know Matt is committed to creating win / win relationships for all suppliers and retailers working with AGI.”
Nitzberg’s appointment reinforces AGI’s long-term commitment to transforming how organizations build trust, alignment, and performance across complex B2B relationships, anchored in rigorous research, evolving operating models, and a clear vision for the future of engagement intelligence.
“As client expectations evolve, the role of insight providers is changing,” said Nitzberg. “Organizations are looking for deeper partnerships and closer connections between insight, action, and impact. Aligning our client-facing teams globally allows us to meet those expectations more effectively and help clients navigate complexity with confidence.”
