To launch the new Grandma McFlurry to multicultural consumers, McDonald’s introduced Sweet Connections, its first-ever AI-led campaign, bridging generational language gaps between American-born youth and their grandparents. Tapping into insights that over 40% of Americans struggle to communicate with their grandparents—especially in multicultural communities—the campaign leveraged AI’s ability to connect generations. Through SweetConnections.AI, users translated heartfelt messages into 30 languages, while commercials featuring real families and AI workshops at community centers deepened engagement. The campaign drove massive impact: the Grandma McFlurry sold out in just 2.5 weeks, web traffic exceeded 145,000 visitors in the first week, and Inc. Magazine called it “brilliant,” urging brands to follow McDonald’s lead in AI-driven marketing.
