Mustache

A good fit

Mustache fits Danish retailers, wholesalers, membership organizations and sports or media publishers that want one Copenhagen-based team to carry a native app from strategy through UX design, backend development and long-term support. The agency publishes a client roster spanning grocery and retail chains operated by Dagrofa (Meny, SPAR and Min Koebmand), industrial and technical distribution (Lemvigh-Mueller, AK Nygart), pharmacy retail (Apotekernes AMBA), sport and media (Bold, DBU), fitness (FitnessX) and other Danish organizations including Nordisk Film, the University of Copenhagen, Rambøll, Bestseller and the Assure Fond.

Services

Mustache groups its published services as consulting and sparring on strategy and feature prioritization, UX and UI design from wireframes to finished interfaces, native iOS and Android app development covering backend and middleware work, and post-launch maintenance and optimization covering monitoring, QA and continuous improvement. Its published case pages also describe taking over and continuing development of apps the agency did not originally build.

Representative work

For Dagrofa's Min Koebmand grocery chain, Mustache built a loyalty app launched in October 2024 that lets customers earn points, receive discounts and follow weekly offers across more than 160 independently run stores, sharing a technical foundation with Dagrofa's other chain apps, Meny and SPAR SAMMEN, through feature flags. The SPAR SAMMEN app, launched in 2019 as a joint effort between SPAR Danmark, Dagrofa and Mustache, adds a scan-and-pay feature to the same loyalty model. For sports and lifestyle publisher Bold, Mustache rebuilt the app in 2019 around personalized news feeds by club and league. For fitness chain FitnessX, Mustache built a member app with mobile-based door access alongside booking and membership management. For steel and technical wholesaler Lemvigh-Mueller, Mustache took over and continues to develop the LEMU app, which combines a product catalogue, ordering and customer data for tradespeople, including click-and-collect ordering and in-store mobile scan-and-pay.
