London, 1st June 2025 – We are pleased to welcome Margaret Wagner to Ciesco as a Senior Advisor supporting our clients with their marketing, digital and data platform growth agendas.
Margaret brings with her over 30 years of experience in delivering both organic and inorganic growth strategies across the marketing, digital, and technology services landscape. Her deep expertise spans capability expansion, solution development, platform integration, and go-to-market strategies for both agencies and their clients. She is widely recognised for her belief that successful M&A hinges on culture and strategic fit, principles that have defined her leadership approach.
For the past decade, Margaret held senior leadership roles at Merkle, dentsu’s global customer experience brand. She joined as Chief Growth Officer for EMEA, driving more than £65m in new business sales. She was later appointed CEO of EMEA, where she led the integration of over 10 acquisitions, contributing significantly to Merkle’s growth from a 15-person team to a 4,800-strong regional powerhouse. During her tenure, she built the EMEA sales and marketing engine, developed strategic partnerships with Adobe, Salesforce, AWS, and Google, and established scalable lead generation platforms across markets.
Her leadership portfolio also includes global and regional roles at Wunderman (now VML Digital), Havas, and RAPP, where she led global accounts such as Citi Cards, Samsung, and Land Rover, and spearheaded corporate development initiatives.
A graduate in Medieval History from New York University, Margaret has built a career on hands-on experience, combining a deep commercial mindset with a practical understanding of how to scale and integrate complex organisations. She is a strong advocate for active, inclusive leadership, having managed high-performing global teams throughout her career.
Margaret joins the Ciesco team alongside existing Senior Advisors Matt Bruun, a DevOps and Cybersecurity expert, Daniel Singer, a specialist in Digital Data, AI and Customer Research, and Chandra Rao, who is a Commercialisation specialist across Healthcare and Pharma.
