Summit Offstage A connection app built for Web Summit 2026 attendees, live only during the event week.

The idea Web Summit brings 70,000+ people from all over the world to Lisbon for a few days. Many come alone, have only a few minutes to introduce themselves, or notice someone interesting and never get the chance to talk. I had the idea to create an app that turns those missed moments into real connections, and built it in a few days, right before the event.

What it does 👋 People: attendees create a badge-style profile with their interests (networking, friendship, a co-founder or a date) and the dates they’re in Lisbon, then connect with people who share them 🍽️ Plans: anyone can create a group plan (dinner, drinks, exploring the city), and the creator approves who joins. Each plan gets its own group chat 📍 City events: attendees share events happening around Lisbon, mark if they’re going (publicly or privately) and see who else will be there 💬 Chat: private chat opens only when both people want to connect

Built for one week only The app was designed around the event dates. Profiles show who’s in town and when, plans happen before, during and after the Summit, and all accounts and data are deleted once the event ends.
