Stagwell bought Maru in 2022 and has owned US-based The Harris Poll since 2017.

Over the past two years, The Harris Poll and Maru have been working together to integrate their advisory, analytics and research services.

The rebrand will align the two organisations under one single brand identity. There are no changes to Maru’s UK legal entity, leadership, operations or client services.

The company said the name change represented ‘a new chapter’ and would result in expanded research capabilities and access to global thought leadership.

Sarah Beams, managing director, The Harris Poll UK (pictured), said: “Becoming the UK branch of the globally respected Harris Poll brand maintains the local expertise we’re known for, backed by a name that better reflects the depth and impact of our work.”

John Gerzema, chief executive, The Harris Poll, said: “This rebrand reflects our commitment to building a unified, insight-driven organisation across markets.

“The UK team brings proven capability, strategic thinking, and real energy to everything they do, and we’re proud to have them representing The Harris Poll brand as we move forward together under one name.”
