HireInfluence Runs Creator Campaign for OREO x McDonald's Shamrock McFlurry

HireInfluence executed an influencer marketing campaign for the limited-edition OREO Shamrock McFlurry launch, a collaboration between OREO and McDonald's.

The Houston-based agency worked with lifestyle and food content creators to promote the product during its seasonal run. The campaign marks another instance of major CPG brands using independent shops for social-first activations. McDonald's and Mondelēz International typically work with holding company agencies for traditional media.

HireInfluence specializes in creator partnerships and influencer strategy. The agency has previously worked with brands including Dyson, H-E-B, and Ulta Beauty. The firm was founded in 2011 and operates as an independent influencer marketing agency.

The Shamrock McFlurry combines McDonald's seasonal Shamrock Shake flavor with OREO cookie pieces. McDonald's runs the Shamrock line annually, typically in February and March. This marks the first OREO collaboration in the Shamrock product family.

The campaign went live in late February 2026. HireInfluence confirmed the work via social media on February 28. The agency did not disclose creator count, reach metrics, or campaign budget.

McDonald's has increasingly deployed influencer marketing for limited-time offers and menu launches. The brand's social strategy often runs parallel to traditional advertising, with different agencies handling each channel. HireInfluence did not specify whether it worked directly with McDonald's or through an intermediary agency.
