GBK Collective Appoints Insights Veteran Rebecca Szew as Partner and Chief Client Officer

NEW YORK--(BUSINESS WIRE)--GBK Collective, a leading marketing strategy, consumer behavior, and analytics consultancy, today announced the appointment of Rebecca Szew as Partner and Chief Client Officer. In this expanded leadership role, Szew will oversee GBK’s client research design and thought leadership, partnering closely with the company’s new President of Client Services, Ben Rogers, to grow client relationships, expand capabilities, and continue to drive business impact for the firm’s roster of Fortune 500 brands.

Szew brings more than two decades of experience advising brands on marketing strategy, insights, and growth across the full go-to-market journey, with deep expertise across industries ranging from technology and enterprise services to CPG, ecommerce, entertainment, healthcare, and financial services.

“Rebecca is a rare talent who brings both depth and clarity to even the most complex client challenges,” said Jon Greenwood, Co-Founder and CEO of GBK Collective. “Her leadership, strategic thinking, and commitment to excellence have shaped how we apply better insights to drive results for our clients. I’m thrilled to see her take on the Chief Client Officer role as we continue to grow and evolve.”

Since its inception in 2015, GBK has partnered with dozens of Fortune 500 brands across categories to solve product strategy and marketing problems at scale using a variety of strategic frameworks informed by advanced analytics and custom research. The firm has continued to grow revenue while expanding its global collective of experienced practitioners, providing clients with senior marketing, insights, and analytics. In contrast to the ready-made solutions that many firms propose, GBK designs a bespoke team of experienced practitioners and academic thought leaders for each and every client project.

“Rebecca has made an invaluable contribution to GBK’s growth, and we’re excited to see her influence expand even further in this new role,” said Eric Bradlow, Co-Founder of GBK Collective, Vice Dean of AI & Analytics and Chairperson of Wharton’s Marketing Department. “She brings a clear, client-centered perspective to the way we apply insights and data, ensuring our work is not only analytically sound but highly relevant to business outcomes. Rebecca has helped our clients and teams focus on what really matters: using better data to drive smarter decisions.”

As EVP of Research and Insights, Szew helped establish GBK’s consultative approach to brand and customer strategy, leading engagements that span segmentation, brand equity and drivers, communication effectiveness, customer lifetime value (CLV), and more.

Looking ahead, Szew will continue to shape GBK’s client engagement model, helping brands cut through complexity and apply better data and research to drive growth and key outcomes with customers as the firm applies new tools on behalf of clients from AI to predictive modeling. She is a strong believer in the power of hypothesis-driven research and aligning teams around business outcomes, not just research outputs.

“It’s been a true privilege to help build GBK alongside such a talented team,” said Rebecca Szew. “What makes this place so special is our ability to start with a client’s toughest question and create something custom, rigorous, and practical from the ground up. I’m honored to take on this new role and excited to continue supporting our clients as they navigate growth, complexity, and change in an increasingly competitive market.”

Before joining GBK, Szew held roles at Millward Brown and IRI, where she advised brands such as Intel, Starbucks, Genentech, Expedia, and Neutrogena. Based in LA, Szew holds a Bachelor of Arts in Marketing and International Business from the University of Arizona.
