Case study
Smart City Expo World Congress
Each edition of Smart City Expo World Congress brings together more than 25,000 attendees from 120 countries to discuss the future of cities. Beyond the flagship event in Barcelona, the Smart City Expo network reaches cities across the globe — and Barter supports that expansion. Behind the scenes, Barter runs the full technical office: managing hundreds of speakers, coordinating the scientific programme and keeping every team aligned — from the first brief to the final session.

Challenge
An event that never stops moving
With over 800 speakers, dozens of parallel sessions and stakeholders across multiple continents, Smart City Expo generates a constant flow of changes, confirmations and last-minute decisions. The organiser needed a partner capable of absorbing that complexity without losing control of the programme or the experience.
Solution
A dedicated technical office at the core of the operation
Barter embedded a full technical office team into the event structure — managing speaker selection and briefing, building and maintaining the programme, handling abstract submissions and jury processes, and acting as the single point of contact between content, operations and the live team throughout the entire congress.
Result
A congress that runs itself — from the inside
Every speaker briefed, every session locked, every change tracked in real time. The organiser gained the operational confidence to focus on strategy and growth, knowing that the programme — and everyone in it — was in capable hands. Year after year.

“Having Barter run the technical office meant we could focus on the big picture. Every speaker, every session, every change — handled. We didn't have to worry about the programme because they owned it completely.”
