Getting ready to take over the national letter market
Since 2024 we have been on a meaningful journey with dao to help integrate and connect legacy IT systems and isolated customer touchpoints into one seamless digital experience. In the first half of 2025 we launched dao’s new website (see separate case), and with the deadline of dao taking over the responsibilities of the letter market in Denmark fast approaching, we launched the new app by November 2025. Hereby we have gone full circle in enabling all customers in Denmark to easily manage letters, packages, and magazine subscriptions across dao platforms.
A user-centric app experience
Together with dao set out to create a fully user-centric app experience for both iOS and Android — one that brings all services together in one place and makes everyday life easier for customers. The new app introduces a brand-new purchase flow and service hub where users can: track parcels, buy digital stamps, access receipts, choose between multiple payment options, explore guides and support, and get help from dao’s AI-powered chatbot. In short: more convenience, more clarity, all in one unified touchpoint. We collaborated closely with dao’s product, logistics, and customer service teams to align business needs with user expectations. Our approach combined experience-driven design, scalable technical architecture, and tight integration with existing backend systems — without disrupting ongoing operations. With agile delivery and weekly alignment across all stakeholders, we ensured transparency, speed, and a shared understanding of priorities all the way through launch.
dao has been in the midst of a significant transformation, dealing with legacy systems, new internal capabilities and at the same time the need to develop a new app. What has stood out in the collaboration is their ability to lean into our way of working and make room for trust, even when complexity was high. The app and the purchase flow on the website share the same codebase, which is a deliberate choice that is both technically responsible and commercially sustainable. The result is a solution that is not just new, but one that moves the business forward and creates better experiences for both private and business customers.
CEO Abtion
"Launching both a new app and a new purchase flow in 2025 was a major undertaking, and Abtion played a key role throughout the process. Abtion has been thorough, engaged, and clear, with a strong understanding of both our strategic direction and day-to-day reality. The collaboration has been built on honesty and trust, and today Abtion feels like a truly integrated part of our development team."
Marketingchef, dao
One app to seamlessly manage everything
Overcoming legacy constraints
While we dramatically improved the customer interface, many internal legacy systems remained unchanged. This required smart strategies for presenting complex information clearly and handling customer enquiries efficiently - all without redesigning internal apps or replacing core purchasing flows. By building a flexible API layer and UI patterns that could adapt to system limitations, we ensured a stable, intuitive user experience despite technical constraints.
Future-proof platform for all user needs
dao now has a unified customer app that supports its new national role in the Danish letter market. Customers can manage everything - letters, parcels, and subscriptions - seamlessly from one place, increasing convenience and reducing friction. The launch strengthens dao’s customer experience, supports operational efficiency, and creates a future-proof platform ready for further expansion.
