South Korea-based electronic shelf label (ESL) tech company Solum has partnered with Gander in an arrangement rooted in helping retailers optimise in-store pricing and reduce food waste by driving sell-through.
The tie-up brings together Gander’s product expiry-based pricing intelligence tools with Solum’s ESLs and software as a service platform. The companies say the partnership will make it easier for retailers to ensure the right price is applied at the right time, directly at the shelf edge, therefore helping reduce food waste at the store level.
The theory is that, thanks to the tech, stores will find the process of markdowns less manual and easier to manage across multiple stores. And by connecting expiry-led pricing decisions with real-time shelf updates, retailers will reduce the need for manual interventions, freeing up time for store staff to undertake other tasks.
Spar International, some of the regional Co-op networks, and Waitrose are among Solum’s list of retailer clients in the UK.
Next week’s Retail Technology Show 2026 in London marks the official launch of the partnership.
Stacey Williams, business development director at Gander, commented: “Through our partnership with Solum, grocery retailers can turn every markdown decision into instant, accurate shelf-edge execution.
“By combining Gander’s real-time optimisation and demand activation with Solum’s ESL infrastructure, retailers improve sell-through, protect margin, and reduce food waste, all without adding operational complexity in store.”
Mark Duckworth, country manager for UK & Ireland at Solum, remarked: “As increasing numbers of large UK grocery retailers adopt Solum’s ESL solutions based on proven quality and trust, open collaboration with ecosystem partners like Gander represents an important step forward.
“Through these partnerships, we can deliver sustainability-driven solutions that genuinely reflect the evolving needs of both the market and our customers.”
Gander’s technology identifies short-dated products and automatically applies optimised, rule‑based markdowns based on retailer-defined parameters. It also gives retailers clear visibility of waste performance, compliance, and sell-through rates, while promoting reduced-to-clear products across multiple consumer-facing channels to help accelerate demand.
Integrated with Solum’s Newton ESL platform, expiry-led pricing decisions are automatically synchronised and displayed on shelf-edge labels in real time. According to Solum, the integration enables “fast, reliable communication between central pricing systems and the shelf edge, ensuring updates are executed consistently across store networks”.
