Once you’ve purchased your ticket, you’ll receive an email with access to the event platform a few weeks before the event. Through this platform (desktop & app), you can register for sessions and schedule 1-on-1 meetings with other attendees.
With the login details you receive in that email, you can also access the platform through this link.
If you want to use the app: search for 'Lively - Event Networking' in the Play Store or App Store and fill in the emailadres you used to obtain your ticket for Crossroads.
