The Relevance Group (TRG) is a European network of specialist companies in marketing, data, AI and technology.
TRG was founded on the belief that many organisations hold untapped growth potential in their (customer) data, and that by connecting sources like sales data, behavioural data, research data, marketing data and external sources, that potential can be turned into measurable business growth.
We support organisations in becoming more relevant across every stage of the customer lifecycle. Each company within our group brings its own area of expertise and specialism, and together they form a carefully curated end-to-end offering: from identifying and connecting data sources to developing, executing, and optimising strategies and campaigns.
This shared approach is grounded in a common belief: that relevance is the most powerful currency in modern marketing. The goal of TRG is simple: turning data into business growth.
