That’s a first: He led a creative resurgence at Mother London before becoming Mother’s first global chief creative officer in March 2025—and the agency hasn’t lost a multi-office pitch since. Mother helped build the brand and personality for Anthropic’s AI assistant, Claude, first with the “Keep Thinking” campaign and then the Super Bowl, handled the launch campaign for the blockbuster Battlefield 6 game, and co-founded Mother Berlin.

Anselmo Ramos
Co-founder & Creative Chairman, Gut
Originally honored: David, 2016
Get Gut: Shortly after appearing on our list for the first time in 2016 for his work at David, Anselmo Ramos co-founded Gut in 2018. The agency has since gone on to win Independent Network of the Year, Independent Agency of the Year, and Agency of the Year at Cannes Lions, and Most Effective Independent Agency according to the Effie Global Index in 2023. Acquired by tech consultancy Globant in 2023, Gut has grown to 12 offices and 2,000 “Gutsies” worldwide.
Serve: From the snack aisle to courtside, Ramos’ talent can’t be denied. When Cheetos brought back its Flamin’ Hot Dill Pickle flavor, the “Pickle’s Back” campaign united Megan Thee Stallion and Nickelback for a chip escapade (and a “How You Remind Me” remix) in a clash of music genres that surprisingly worked. And for Wimbledon’s 2025 tournament, the “Dressed for Center Court” Stella Artois campaign made sure its cans met the tournament’s strict dress code. Not the mention the “Jell-Ometer” to gauge fandom intensity.
