Joe is a highly regarded transformational leader with one of the most diverse backgrounds in the advertising industry: he is currently Sam’s Club’s interim Chief Marketing Officer; he has led agencies that specialize in media (Universal McCann), technology (Sapient and Razorfish), creative (Saatchi & Saatchi/Team One), and data (Epsilon and Hawkeye); and he has founded three successful tech start-ups. Joe was named one of the youngest CEOs at Publicis Groupe and at Interpublic Group, and has received numerous awards for creating high-performing, entrepreneurial, and inclusive cultures, including Ad Age’s “40 Under 40.”

In 2024, Joe was named interim Chief Marketing Officer at Sam’s Club, where he is responsible for the retailer’s go-to-market strategy and marketing transformation initiatives.

In 2022, Joe joined Interpublic Group as U.S. CEO of Universal McCann, and led the agency’s transformation. UM rose to #2 from near last in RECMA’s rankings, was named Ad Age’s “U.S. Media Agency of the Year,” Campaign’s “Media Agency Global Network of the Year,” and “Leader” in Forrester’s Media Agency Wave. Under Joe’s leadership, the agency won both the GEICO and General Mills media AOR reviews — two of the largest pitches of the decade — along with 11 other new business wins, adding $3B+ in billings under management and improving new business performance by 36% year-over-year. The agency received 13 “Best Places to Work” recognitions, including Newsweek’s “Greatest Workplaces for Diversity,” Fortune’s “Best Workplaces,” and Campaign’s “Inclusive Workplace” and “Sustainability Standout,” improving employee retention by 40% and Black/Hispanic representation in new hires by 74%. The agency nearly doubled its spend with Black-owned media partners, doubled its commerce billings to $2B, and launched a first-of-its-kind commerce laboratory in NYC. Joe worked with Ryan Reynolds and Maximum Effort to bring industry-first creative content to life for brands like GEICO. Every Friday, Joe hosted all-agency get-togethers called “Java with Joe,” where he answered questions with transparency and spotlighted employees’ diverse passions and backgrounds.

In 2019, Joe was named CEO of Hawkeye, Publicis Groupe’s lead CRM agency, and was handed the baton from the agency’s beloved founder, Steve Dapper. Under Joe’s leadership, Hawkeye nearly quadrupled in size, added 42+ clients to its roster, and became one of North America’s largest pure-play CRM agencies, supporting clients such as Google, AT&T, FedEx, USAA, and Capital One. During Joe’s tenure, the agency was selected as a finalist for “Marketing Agency of the Year” and “DE&I Company of the Year” by The Drum, and its employee retention rates were the highest across Publicis Groupe.

To support Publicis Groupe’s $4.4B acquisition of Epsilon, Joe established and led the holding company’s CRM Practice, integrating capabilities from Epsilon, Sapient, Publicis Media, and creative agencies, as well as strategic partners Adobe, Salesforce, and Microsoft. In its first year, the practice grew CRM revenue to $2B+, and was named “Leader” in Forrester’s Loyalty Service Providers Wave, with the highest scores across all 15 of the Wave’s criteria.

While at Razorfish, Joe led the T-Mobile digital AOR account, spearheading the industry-revolutionizing “Un-Carrier” repositioning, and then pitched, won, and led the Honda/Acura digital AOR account and reopened and led the agency’s Los Angeles office. At Saatchi & Saatchi/Team One, Joe was Head of Digital on the Toyota/Lexus account, where he helped open and lead the agency’s Dallas office.

Joe has founded three successful technology start-ups. In 2017, Joe founded TiltShift, the industry’s first AR/VR/xR agency, which pioneered the commercial and consumer applications of AR/VR technology, produced experiences for Nike, Lexus, and Procter & Gamble, and then became a cornerstone of Publicis Groupe’s CGI production capabilities during the COVID-19 pandemic, when traditional production methods were not possible. In 2010, Joe co-founded CloudTix, the world’s first software-as-a-service mobile ticketing platform, and qCloud, the world’s first cloud-based virtual waiting room and queuing system, in partnership with the team at Amazon that would go on to become Amazon Web Services.

Joe is an avid student of leadership and studied under Pulitzer Prize nominee Warren Bennis. Joe is on the board of the American Marketing Association New York City chapter as mentorship chair. He regularly speaks at conferences such as Cannes Lions, CES, and SXSW. He is a member of Ad Age and Meta’s “The List,” where he contributes to articles published in Ad Age. He judges industry awards shows such as the Festival of Media and Adweek’s Media Plan of the Year. He guest lectures at Southern Methodist University and Chapman University. And he created “Launchpad” and “Rocket Fuel,” personal and professional development programs for high-potential executive leaders and early-career employees. In 2005, Joe founded a non-profit in honor of his father Frank, an internationally recognized music educator, which produces the nation’s largest educational jazz festival.

The DeMieros have a multigenerational home in Dallas, TX, where Joe, his wife, and son live with Joe’s father and mother and four dogs.
