Johnny Hornby

Johnny Hornby is best known as the founder of The&Partnership, the innovative agency model he built in partnership with WPP that became one of the most talked-about structural experiments in modern advertising. The&Partnership was designed to embed agency talent directly within client organisations, blending creative, media, data, and technology capabilities under one roof — a model that challenged the traditional holding company structure and anticipated the industry's shift toward integrated, data-driven marketing. This approach attracted major clients including News UK, Toyota, and Sky, and positioned Hornby as a forward-thinking operator at the intersection of creativity and advertising technology. Before founding The&Partnership, Hornby had a distinguished career at CHI & Partners, which he co-founded and built into a respected creative agency in the UK. His trajectory reflects a consistent pattern of entrepreneurial agency-building, with a particular emphasis on aligning creative output with measurable commercial performance — a philosophy that resonates strongly in the performance and data-driven advertising era. His work helped shape conversations around agency transformation, client-agency integration, and the role of technology in creative businesses. More recently, Hornby has stepped into a high-profile entrepreneurial venture outside of AdTech proper, co-founding Hawkstone, a craft lager brand associated with Jeremy Clarkson's Clarkson's Farm. While this represents a pivot from advertising, his background in brand-building and marketing strategy underpins the venture. His influence in the advertising and agency world remains significant, particularly around integrated agency models and the commercialisation of creativity.
