What Golley Slater does

Golley Slater is a UK-based full-service advertising and marketing agency founded in 1957 and headquartered in Cardiff, with additional offices in Cirencester, Leeds, and London. The company operates across 11 interconnected service disciplines: advertising and creative, B2B marketing, branding and design, content/film/animation/VR production, CRM and marketing automation (delivered as a HubSpot Gold Partner), direct marketing, media planning and buying, PR/social/influencer marketing, research/strategy/planning, retail and shopper marketing, and SEO. Its technology stack combines HubSpot's CRM and automation platform, in-house creative production capabilities spanning TV, VOD, cinema, 3D rendering, and virtual reality, alongside programmatic media buying with direct DSP access including Amazon Prime and Disney+ inventory. The agency is one of approximately 30 UK agencies holding IPA Effectiveness Accreditation and has been a member of the ICOM global independent agency network since 2009.

The company's go-to-market is direct enterprise client engagement, targeting major brands across FMCG (Coca-Cola, P&G, Nestle, AB InBev, Tesco), automotive (Bosch, Mitsubishi), financial services (Nationwide), and the Welsh public sector (Transport for Wales, Welsh Government, NHS Wales). Revenue is generated through project-based professional services fees for integrated marketing campaigns and standalone service lines, with measurable client outcomes including a 50% reduction in railway trespassing for Transport for Wales and 64.8 million video views for a Bosch pan-European B2B campaign. Pricing is not publicly disclosed and is structured around project scope and service requirements.

Golley Slater transitioned to a 100% employee-owned business in September 2025, placing the entire company in trust for approximately 130 employees, with stated specialist headcount of 170+. Ownership structure, leadership under CEO David Longden, and operational model remain unchanged. The company reports no parent entity, no subsidiaries, no funding rounds, and no public-company plans, operating as an autonomous private entity serving a long-tenured enterprise client base across the UK and select international markets via its ICOM affiliation.
