City of Rotterdam — Driving Engagement through the OndermijningTour App
The City of Rotterdam wanted to connect employees from different departments to share insights and strengthen cooperation in tackling subversive crime. To make this knowledge exchange interactive, the city hosted the one day Stop Ondermijning! conference in De Kuip stadium, bringing together more than two hundred employees for a day of learning and collaboration.

The challenge: connect departments and share knowledge about subversive crime through an interactive, secure and energising event experience.
From idea to live app in three weeks
Together with event agency VKOZ, Savvy Congress developed the OndermijningTour app in just three weeks. The city provided the content, VKOZ coordinated the event and Savvy handled the full design, setup and technical delivery of the app.
At the venue, every workshop featured a Savvy Tour column with a unique QR code. Participants used the app to scan these codes and instantly access workshop materials, related questions and interactive challenges. Anyone scanning without logging in only saw general information, keeping sensitive content secure.
Access was simple. Registered employees received a personal SMS link for instant login without downloads, while walk-in visitors used a printed ticket with a QR code to join directly.
Savvy's digital solution
Savvy created a fully branded and low threshold app that connected, informed and motivated participants throughout the day.
- Custom event app designed in the City of Rotterdam's visual identity
- QR code integration for secure workshop access
- Anonymous feedback module visualised live on the "Top" and "Tip" walls
- Gamification features with quizzes and a live leaderboard
- Personalised agenda and floor plan for easy navigation in De Kuip
- Real time dashboard tracking feedback, knowledge results and engagement
The result
The combination of interactive tools, gamification and feedback created a highly energetic event. Employees shared what worked well and what could improve, while testing their knowledge across workshops. Results were displayed live in the app and on large screens, providing immediate insight into learning outcomes and engagement levels.
For the organisers, all data was visible in real time through the Savvy dashboard, offering a clear view of the event's Return on Engagement. By the end of the day, the initiative had strengthened collaboration, sparked conversation and made learning measurable.
