During the 2026 HYROX World Championships in Stockholm, HYROX invited spectators to predict the winners of the singles, doubles, and mixed team categories throughout the two days of competition. Accessible via a QR code displayed on a giant screen, the experience allowed the public to make their predictions from their mobile devices, then confirm their participation via a chatbot to enrich the CRM database. With an 86% engagement rate and 650 email addresses collected, this mobile-first campaign transformed the wait between events into a genuine opportunity for engagement and the collection of qualified data.
