What GPMD does

GPMD (Legal: GPMD Limited) is a London-headquartered, privately held ecommerce agency founded in December 1999 by Mark Slocock and Graham Vickage, originally as Digital PlanIT. Operating as a professional services firm, the company delivers end-to-end ecommerce engagements including strategy, UX/UI design, custom theme and app development, platform migrations (replatforming), integrations, and AI process-automation consultancy. Its primary platform expertise centers on Shopify (including Shopify Plus, Shopify B2B, and Shopify POS) and BigCommerce, with a portfolio of secondary technologies (n8n workflow automation, Algolia, Klaviyo, Klevu, ShipperHQ, Adyen, Linnworks). A proprietary differentiator is Apio, an iPaaS integration platform built and deployed exclusively across GPMD client builds.

The company serves both B2C consumer brands and B2B brands looking to digitize wholesale operations, with a particularly strong niche in bringing B2B commerce onto Shopify via its SparkLayer partnership. Named clients span enterprise and mid-market retail and food/hospitality (MUJI, The River Cafe, ARAM, NIP+FAB, Shoes For Crews, Japan Centre, Lazy Susan, The Fold Line, Butterflies Eyecare, Balloon Market), with documented cross-border European deployments covering up to six markets. The team is internationally distributed with 11–50 employees, and the firm operates from Eagle House, 163 City Road, London (Registered Company Number 5092139).

Revenue mechanics are professional services–based: bespoke, quote-priced project engagements plus longer-term partnership retainers, sold via direct enterprise sales, inbound website leads, and platform partner referrals (Shopify, BigCommerce, SparkLayer). GPMD is bootstrapped with no disclosed external funding, private equity involvement, or acquisition activity. Marketing is content-led (blog, SEO, industry events such as Web Summit and BigCommerce Partner Summits) and partner-amplified. Recent strategic emphasis has been on AI Consultancy, the Apio integration platform, and elevating the Shopify Plus and B2B positioning.
