Case
Omnichannel growth – Gamma
The client
Gamma, one of Belgium’s most well-known DIY stores, is an omnichannel retailer and part of the Dutch group Intergamma.
In Belgium, Gamma ranks among the top 3 in the DIY sector. Each week, approximately 160,000 customers visit the 86 Gamma stores in Belgium, with an equivalent number visiting the webshop. Around 1,000 employees serve customers in-store.
The challenge
In Belgium’s competitive DIY market, the goal was to maintain and grow Gamma’s market share. With Belgian DIYers increasingly orienting themselves online before visiting physical stores, the battle for the consumer begins digitally. A well-thought-out assortment, the right pricing strategy, and guiding online visitors with expertise through content were key components of the online strategy. Maximizing returns from digital performance channels was crucial to convince targeted users either to make an online purchase or, at the very least, visit a store with purpose.
With a large assortment (20K+ references), a fast-paced promotion strategy, and a flexible market, the Intergamma team (also responsible for Gamma Netherlands and Karwei) faced the challenge of not only ensuring the right skills and capacity but also adapting these to the Belgian reality (Flemish + French).
Our Approach
Through our TaaS (Team as a Service) model, we supplemented Gamma’s internal team with a group of Paid Advertising specialists. This team provided not only the necessary performance skills and capacity but also challenged the overall strategy and its translation to the Belgian market.
The team worked 95% remotely, maintaining close communication with the internal team via calls and consultation moments. A joint KPI dashboard served as the compass for both teams. This approach allowed the Hybrid team to operate largely autonomously while ensuring responsibilities and expectations were crystal clear.
How We Worked
Starting with the objectives, our team conducted a deep dive into the accounts and data. Our comprehensive performance audit gave us clear insights into where returns could be improved and how priorities should be set. Based on this data, we worked with the Gamma team to establish our action plan.
