What Arthur London does

Arthur London Ltd is an independent strategic and creative communications agency founded in 2008 and headquartered at Temple Chambers, 3-7 Temple Avenue, London EC4Y 0DP, with 16-24 employees including part-time specialists. The company specializes in two primary verticals: B2B clients — chiefly asset and investment management (Vontobel, Janus Henderson, Aviva Investors, Lazard, M&G, Capital Group, Candriam) and professional services firms (Amey, Argon & Co, Ascot Lloyd, Pay.UK, NatWest) — and UK charity/not-for-profit organizations (Centrepoint, Dementia UK, St John Ambulance, RSPCA, Save the Children, Stroke Association, Age UK). Service offerings span brand strategy, positioning, messaging, identity, campaign creative, advertising, digital, integrated campaigns, lead generation, social media and email marketing, and go-to-market planning, delivered through direct sales engagement organized by sector (InvestorMarketing, ProfessionalServices, CharityBranding, Fundraising, Legacy email channels).

The agency operates on a project-based professional services revenue model with no publicly disclosed pricing, no app or API product, and a standard WordPress-based technology stack comprising Google Analytics, Google Ads/Adsense, Wordfence security, Adobe Fonts, and Lead Forensics for web analytics. The technology is presentation-layer rather than product-layer; Arthur London's competitive positioning rests on sector specialization, emotional creative differentiation in rational-heavy categories, and demonstrable campaign outcomes (e.g., 62% campaign page-user uplift and 15.4m social impressions for St John Ambulance's 'Save a Life September'). Distribution is entirely sales-led direct to enterprise and mid-market clients, with no resellers, marketplaces, or platform channels. The company is privately held, founder/management-owned with no disclosed external investment, no parent company, no subsidiaries, no M&A history, and no funding rounds.

The business is registered in England & Wales (company number 6586889), trades under the DBA 'ARTHUR', and reports turnover below £36M — below the threshold for mandatory Modern Slavery Act disclosure. Senior Partner Darren Lassiter is the named leadership figure, authoring the agency's 'News and Views' thought leadership blog covering asset management marketing topics. Customer concentration is diversified across 25+ named logos spanning multiple industries, though revenue concentration cannot be quantified given lack of financial disclosure.
