The advertising business, which trades in the manufacture of feelings, is not always adept at processing its own. On Saturday, the industry lost Mark Green, the global chief executive of Droga5, who died of a heart attack in New York at 53.

Mr. Green, known widely as "Greenie," had been running Droga5 since 2024, having arrived in New York after nearly two decades building agencies in Australia. He is survived by his wife, Rachel, and two children, Ari and Gisele.

His death was confirmed by Droga5, which is part of Accenture Song, the marketing services arm of the consulting giant Accenture. "He will be remembered not only as the visionary that he was, but for his generosity, his humor, and his empathy," the company said in a statement.

Mr. Green began his career at Coca-Cola before moving agency-side, with stops at DDB, Clemenger BBDO and Saatchi & Saatchi. In 2006, he co-founded The Monkeys in Sydney with Justin Drape and Scott Nowell. The agency became one of Australia's most celebrated creative shops, winning business from Telstra, Qantas, Toyota and the Sydney Opera House, among others.

Accenture acquired The Monkeys in 2017 in a deal reported at $63 million — part of a wave of consulting-firm acquisitions that reshaped the competitive landscape of the industry. Mr. Green stayed on, eventually overseeing Accenture Song's operations across Australia and New Zealand before his move to New York.

His proudest creative moments came in consecutive years at the Cannes Lions festival. In 2023, The Monkeys won the Dan Wieden Titanium Grand Prix for "The First Digital Nation," a campaign proposing that Tuvalu preserve its statehood online as rising seas threaten its physical territory. In 2024, the agency took a Film Grand Prix for "Play It Safe," a Sydney Opera House campaign starring Tim Minchin.

(The work suggested that advertising could occasionally do something other than sell things, a notion that remains controversial in some quarters.)

"Australians like to compete and win on the world stage," Mr. Green once told Campaign. "I think it's almost a fear that we might be forgotten if we don't."

He will not be.
