What Four does

Four Agency Worldwide Limited is an independent, integrated media, creative and communications agency headquartered in London, operating across the UK and the MENA region. The firm organises itself around four hero sectors — Health, Government, Future Industries and Lifescapes — and serves a roster of named enterprise and public-sector clients including Welsh Government, NHS, Ministry of Justice, Home Office, American Express, ConvaTec, JTRE London, Grosvenor and Alvarez & Marsal. Media planning and buying alone is described as representing around a third of fee income across more than 90 countries, and the agency holds coveted government roster positions in the UK, Wales and MENA.

The agency's core technology is The Difference Engine, a proprietary AI- and human-powered campaign planning, implementation and measurement platform that integrates more than 70 insights, research, channel, media, trends and behaviour change tools across four phases (FOCUS, UNDERSTAND, ENVISION, LEARN). Complementary proprietary offerings include the VOICES influencer-marketing methodology (scoring influencers on a 1–100 relevance/reach/resonance scale) and the Protect crisis-communications offering. Productised training lines — The Message Engine (including the 1-3-6-2 media training programme) and the AI in Marketing Masterclass — extend the IP beyond pure agency engagements. Governance of AI use sits with an AI Council led by the chief digital and AI officer.

Four operates a professional services, B2B revenue model combining project-based and retainer engagements sold directly through a 250-strong team of sector specialists across seven offices (London, Cardiff, Aberystwyth, Sheffield, Abu Dhabi, Dubai, Riyadh), with global reach enabled through thenetworkone's network of 1,200 agencies in 116 countries. Pricing is not publicly disclosed and is described as quotation-driven. The business is founder-led by Nan Williams (Group CEO) and Einir Williams (Group MD), with co-founder Ray Eglington leading communications globally and the MENA business; the company has executed an M&A programme of more than a dozen acquisitions alongside organic expansion.
