Large-Scale App-Based City Challenge, Downtown Lisbon
HeadBox commissioned Go Discover Portugal and Synergized Events to design and deliver a fully bespoke, app-based city challenge in Lisbon for a large international real estate company expanding its operations across Iberia.
We built a custom web application from scratch, in the client’s brand colours and house style, that took 220 sales professionals on a two-hour journey through downtown Lisbon — engineered end-to-end within an exceptionally compressed 10-day window from concept to live execution.
10 Days, City-Wide, Zero Margin for Error
The project launched with just 10 days spanning full concept development to live execution. The client then introduced extensive, late-stage adjustments to team logistics, communication structures, and city-wide dispersion — requiring intense operational agility, rapid technical deployment, and around-the-clock coordination to protect the participant experience under extreme delivery pressure.
A Bespoke App, Built and Deployed in 10 Days
- City-wide team experience — a scaled, multi-route urban challenge optimised for 220+ participants moving simultaneously across Lisbon
- Bespoke digital application — built, tested, and deployed entirely within the 10-day timeframe, in the client’s own brand colours and house style
- Interactive navigation and digital checkpoints across key Lisbon historic zones
- Real-time engagement loops, prompt submissions, and instant route navigation
- Custom-shot instructional video assets guiding participant flow
- A multi-channel communication infrastructure supporting complex team coordination
One App, Six Challenge Types
Every challenge type tested something different, keeping energy high and competition real across the whole city.
Video
Short video responses judged for creativity and teamwork.
Music
Identify tracks and collaborate on musical tasks.
Puzzles
Logic and observation using the city as the backdrop.
Riddles
Written clues connecting culture, language, and place.
Quizzes
Time-pressured questions on culture, history, and brand.
Collaboration
Whole-team tasks building real connection while competing.
Nine Facilitators, One Fully Insulated Experience
Live deployment was managed by a dedicated senior and technical team overseeing complete logistics on the ground — continuous participant briefings, live platform monitoring, rapid team communication support, and comprehensive scoring metrics. Despite a highly dynamic operational environment, every one of the 220+ guests remained fully insulated from the backend complexity running behind the scenes.
- Executing large-scale, high-profile programmes within highly compressed timelines
- Rapidly developing, testing, and launching client-specific bespoke digital platforms
- Dynamically scaling operational resources midstream to absorb shifting client demands
- Managing complex crowd dynamics and logistical flow across an active metropolitan environment
