Context

Tech Talks Brussels is an annual developer conference that outgrew their Eventbrite setup. They needed custom registration tiers, better sponsor integration, and data they actually owned. Previous events had chaotic check-in lines and no way to measure session popularity.

Constraints

  • !Handle 500+ registrations without crashing
  • !Multiple ticket types with early-bird pricing
  • !Sponsors needed prominent, measurable placement
  • !Check-in had to work offline (venue WiFi unreliable)

Approach

We built a custom registration flow that felt premium but worked simply. Sponsor pages got dedicated sections with lead capture. The check-in app was designed for offline-first with sync when connected. Every interaction was tracked for post-event reporting.

What We Built

  • Multi-tier registration with discount codes
  • Speaker and schedule management
  • Sponsor showcase with analytics
  • PWA check-in app with QR scanning
  • Post-event survey and analytics dashboard

Outcome

Registration sold out 3 weeks early. Check-in averaged 8 seconds per attendee (down from 45). Sponsors received detailed engagement reports that directly led to renewals.

First year we had actual data on which talks people wanted. Sponsors got reports they could show their bosses. Already planning next year's improvements.
