Our Take

The work index publishes 17 named app projects for clients including Migros, Swisscom, Coop, ETH Zurich and Sonepar, several carrying dated Best of Swiss Apps awards from 2013 through 2024 (a Master and multiple Golds for Teena in 2022; Gold for the 2024 Uepaa relaunch), and the About page names 11 staff including two partners at a registered Zurich AG.

Case study pages lean toward finished features and award badges over published method: the Uepaa page cites 120,000+ network users and ~90,000 alarms processed annually but shows no research findings or before/after metrics, and the UX service page lists a 7-step process yet does not document user interviews, usability testing or personas.

Depth is clearly weighted toward native iOS/Android and cross-platform (Flutter, React Native) engineering plus visual/interaction design rather than evidenced upstream research.

It fits teams that already know their product and arrive with their own user research, and mainly want a decorated Zurich studio to execute the design and build to an award-winning finish—not a discovery-and-strategy partner.

Key strengths

  • 17 published app projects for named clients (Migros, Swisscom, Coop, ETH Zurich, Sonepar) with dated Best of Swiss Apps awards spanning 2013-2024, including a 2022 Master for Teena and 2024 Gold for Uepaa.
  • Registered Zurich AG with 11 named team members and two named founding partners, plus Swico membership and a Swiss Made Software label.
  • Breadth across native iOS/Android and cross-platform stacks (Flutter, React Native), with one quantified production result published (Uepaa: 120,000+ users, ~90,000 alarms/year).

Good to know

  • Ask for the research and testing detail behind a case study (interviews, usability sessions, iterations), since published pages show features and awards rather than method.
  • Request adoption or conversion metrics for projects beyond Uepaa, as most of the 17 projects list awards but no user or business outcomes.
  • Confirm the rate band and current team availability in writing, since the site states a team of 11 and 15+ years against the directory's earlier figures.
