Leah Meranus Joins PMG to Drive Customer Success

PMG today announced the appointment of Leah Meranus to SVP Customer Success, a newly created customer leadership role focused on advancing PMG’s customer partnerships and accelerating transformational business growth across its roster of leading brands. Effective in September, Meranus will be based out of PMG’s New York office and report directly to Jon Dupuis, President of PMG. 

Dupuis shared: “We’re absolutely thrilled to welcome Leah to PMG. Her proven ability to lead global business at scale, transform brands, and inspire teams makes her an incredible addition to our leadership bench. Leah will help shape what’s next for our customer partnerships and further amplify the impact we deliver across the businesses we serve.”

Meranus, having most recently served as CEO of Dentsu X North America, brings more than two decades of experience in agency leadership and brand transformation across a number of firms, including 360i, Initiative, Mediacom, and PHD. Her career has been defined by building and scaling innovative customer partnerships, fostering high-performance teams, and guiding marketing and media for some of the world’s most well-known brands, including JPMorganChase, Heineken, JCPenney, Revlon, and Unilever.

"I was drawn to PMG because of its people-centric culture, future-forward business model, and commitment to real innovation," said Meranus. "PMG isn’t reinventing legacy models or retrofitting for the future. It is already operating there with a foundation rooted in technology and a team that is trained and empowered to lead what’s next. The Alli operating system stands out as a true differentiator, combining unified data, automation, and intelligence in one platform to drive meaningful, customer-centric outcomes."

The addition marks another milestone in PMG’s investment in senior talent to support its expanding customer base and continued business momentum. Meranus’ hire follows a series of high-profile leadership appointments, including Chad Stoller as Global Head of Media and Andrea Terrassa as Chief Operating Officer. These additions reflect PMG’s commitment to shaping the future of marketing through expertise, innovation, and operational excellence.

Her arrival also comes amid significant business expansion for the agency. In June, PMG acquired Momentum Commerce. In its first major public analysis under PMG, Momentum Commerce demonstrated its extensive visibility into the marketplace, observing brands collectively doing over $7B in GMV on Amazon US annually. During Amazon's first-ever four-day Prime Day event in 2025, the company tracked $750 million in US Amazon transactions and revealed a 4.9% year-over-year sales increase for Prime Day compared to the previous year's equivalent period. PMG also recently acquired UK-based RocketMill and media agency Camelot, broadening its global footprint and retail media capabilities. 

As part of its ongoing commitment to advancing the technology and AI foundation of the marketing industry, PMG unveiled Alli Marketplace at this year’s Cannes Lions. This first-of-its-kind media-buying solution is fully integrated into the proprietary Alli operating system. The launch featured 22 initial platform and publisher partners and offers marketers unprecedented control, transparency, and speed through automated, intelligence-driven media investments.
