M+C Saatchi Talk Appoints WPP's Callum Powell as Head of Brand PR & Influence

Mar. 31, 2026

M+C Saatchi Talk has appointed Callum Powell as Head of Brand PR & Influence, a newly created role that marks the next step in the agency’s evolution of its culture-first story-making proposition.

Powell joins at a time of continued momentum for the agency. The role brings earned storytelling and creator culture closer together, strengthening the agency’s ability to deliver culturally relevant work that puts clients at the centre of meaningful conversations.

Powell brings 14 years of experience spanning global agency and in-house roles. Most recently, he was Global Business Director at Ogilvy where he led global and EU brand PR for the Coca-Cola sparkling flavours portfolio. Prior to this, he was at L’Oréal, leading 360 brand communications for brands within the luxury professional products division.

In his new role, Powell will lead the strategic direction for major accounts, scale the agency’s creator-led offering, and further integrate brand PR and influencer marketing capabilities. His remit is designed to ensure influence is embedded into the creative process from the outset, enabling more seamless, earned-first campaigns. By uniting these disciplines under a single leadership pillar, the agency aims to enhance its ability to build authentic brand communities and drive cultural relevance for its global client roster.

He will work across clients including Formula E, Revlon and Burberry Beauty Global, and will report to Amaya Alvarez, Managing Director.

Amaya Alvarez, Managing Director, M+C Saatchi Talk, said:

“We’re thrilled to welcome Callum at a time when M+C Saatchi Talk is firmly on the ascent. This newly created role reflects our commitment to a culture-first story-making proposition, bringing earned and creator culture into closer alignment. Callum’s experience at L’Oréal and Ogilvy strengthens our luxury and beauty credentials, while advancing our ambition to deliver globally resonant, culturally nuanced stories that keep our clients at the centre of the conversations that matter most.”

 

Callum Powell, Head of Brand PR & Influence, M+C Saatchi Talk, added:

“Joining M+C Saatchi Talk during its 25th anniversary year is a proud moment. I look forward to working closely with Amaya on pivoting the agency offer from one of storytelling to story-making – moving beyond just sharing a narrative to actively creating the moments that make brands worth talking about. I’m excited to lead on the integration of our brand PR and influencer capabilities, ensuring that earned-first creativity and cultural influence are at the heart of everything we build for our clients.”
