Unique pint

Pilsner Urquell approached us with a deceptively simple brief: “turn a paper stamp card into a mobile loyalty experience.” We kicked off with rapid‑fire workshops - marketing, product, and tech in one room - mapping every user touch - point and defining a lean success metric for activation. From there we sketched dozens of flow ideas on whiteboards and sticky notes until the daily‑stamp mechanic and nine‑slot “mosaic” emerged as the most intuitive path.

With the core mechanic set, we moved into structure. Low‑fidelity wireframes laid out the navigation (home, scan, rewards, profile) and let us validate each step with quick hallway tests. Once the flows proved friction‑free, we layered on the brand: rugged stone textures, deep green accents, and the unmistakable Radegast badge, all aligned with Pilsner Urquell’s broader design system to keep legal and brand teams happy.

The launch proved the concept. In the first weeks, the app pulled in several thousand registrations and reached a healthy activation rate. For a project that started as “just a digital stamp card,” it shows how tight brainstorming, disciplined UX processes, and iterative wireframing can turn a small ask into a meaningful, data‑backed win for the brand.
