What GAMMA does
GAMMA, operated by Intergamma B.V., is the largest do-it-yourself retail chain in the Netherlands and a leading DIY brand in Belgium. Founded in 1971 as the country's first self-service home improvement store, GAMMA today runs 166 franchised stores in the Netherlands and 84 in Belgium under a franchise model in which independent entrepreneurs own individual stores while Intergamma centrally controls the brand formula, assortment, purchasing, logistics, and marketing. The product platform spans more than 30,000 SKUs across paint, tools (including SKIL 20V cordless), wood, building materials and insulation, flooring and tiles, sanitary and kitchen, garden, and window decoration — serving DIY consumers tackling home improvement, renovation, garden, and maintenance projects.
The business operates an omnichannel go-to-market combining physical retail, a webshop (launched 2013 in NL, 2014 in BE) with click-and-collect, a mobile app, the GAMMA Voordeelpas loyalty card offering 20-40% discounts, a tool rental service (Gereedschap Huren), a professional installation service (GAMMA Klusservice), and an extensive content library of 350+ step-by-step DIY plans with how-to videos. Pricing is consumer retail (VAT-inclusive), with loyalty-driven promotional pricing as the primary discount mechanism and dedicated outlet/web-only promotions layered on top.
Revenue is generated through wholesale purchasing margins, franchise fees, marketing contributions, and services captured at the Intergamma corporate level (approximately 370 employees across Leusden and Antwerp offices), while end-consumer sales are executed by the franchised store network. Marketing spans TV, online, radio, social, catalogues, email, and app channels, including a major 2026 brand campaign reviving the iconic "Dat zeg ik. GAMMA." pay-off. The customer base is fragmented across millions of Dutch and Belgian consumers, with no enterprise or named-account concentration.
