What FUNCTION LONDON LIMITED does

Function London Limited is a London-based Shopify Premier Agency operating as a professional services consultancy for fashion and luxury retail brands. Founded in 2021 and headquartered at 71-75 Shelton Street, Covent Garden, the firm specialises in Shopify Plus development, theme architecture, performance optimisation, and platform migrations for premium ecommerce operators. Its client roster includes over 25 named brands spanning enterprise and mid-market fashion, luxury, beauty, and jewellery verticals — including Represent, Fred Perry, Wales Bonner, Dover Street Market, Jessica McCormack, Maharishi, Margaret Howell, and Comme des Garçons (CDG). The firm positions itself as a strategic long-term partner rather than a transactional vendor, emphasising technical excellence, code quality, and brand-aligned ecommerce experiences.

The company delivers through nine core service lines: Ongoing Support, Creative Partnerships, Unified Commerce & Integrations, Data Migrations, Strategy & Consultation, Technical Development, Integration Services, Compliance, and Creative Services. Technical capabilities include custom Shopify Plus theme development and rebuilds, code audit and refactoring (with documented outcomes such as removing 14,000+ lines of unused code for Represent), Magento2-to-Shopify Plus platform migrations with ERP integration, multi-language and regional routing for international expansion, and WCAG 2.1 AA accessibility compliance certification. The firm maintains a 30+ technology partner ecosystem covering marketing automation, subscriptions, analytics, loyalty, accessibility, and ERP — including Klaviyo, Gorgias, Recharge, Yotpo, GlobalE, Brightpearl, and Allyant — alongside strategic creative partnerships with Trends & Culture, A Common Purpose, and Grebban.

The business operates on a professional services model combining project-based builds with recurring support retainers. Pricing is quote-based and not publicly disclosed. The company is privately held, with 1–10 employees, no disclosed funding, no reported M&A activity, and no publicly named leadership team. Distribution is direct enterprise sales supplemented by Shopify's Premier Agency partner network. The company is privately incorporated in the United Kingdom, has no published revenue, and does not disclose financial performance metrics.
