What Door4 does

Door4 Limited is a UK-based, conversion-focused digital marketing agency founded in 2000 by Leon Calverley and headquartered in Burnley (Lancashire) with additional operations in Manchester. The firm operates as a full-service partner for ambitious brands and retailers, organised around three integrated service pillars: Acquisition (SEO, PPC, Paid Social, Paid Search and Shopping, Content Marketing), Conversion (Conversion Centred Design, CRO, User Research and Planning, Brand Storytelling), and Web Development (e-commerce builds across Adobe Commerce, Shopify, WooCommerce, and Magento, plus integrations and support). A newer GenAI Marketing Automation module layers generative AI capabilities for content, CRM, predictive analytics, and social media workflow automation on top of the core service offering.

Door4's go-to-market is sales-led and consultative, targeting enterprise and mid-market clients across at least eight verticals including Home and Garden, Family/Fostering, Automotive, B2B, B2C, Legal, Insurance, and Government/Utilities. Pricing is quote-based and structured as multi-year retainer engagements; no public pricing exists. The agency also runs the Decoding Digital event series and The AI Lab workshops as both thought-leadership and pipeline-generation assets.

Technology stack spans Adobe Commerce, Shopify, WooCommerce, WordPress, Magento, Salesforce, HubSpot, Mailchimp, Google Analytics, Google Ads, and Microsoft Ads, supplemented by custom GraphQL/Docker-based solutions for specific clients (e.g., the InstaGroup installer portal). The company is privately held, founder-controlled, with no disclosed external funding or institutional investors. Headcount is in the 11-50 band. Reported customer outcomes include a 403% sales uplift at Empress Mills, 88% conversion rate increase at National Fostering Group, 131% conversion uplift at Chillblast, and ROAS improvement from 400% to 600% at UK Tiles. The firm was shortlisted for the Red Rose Awards 2026 in the AI and Tech Innovation category.
