I've used Bizzabo for my conferences Cloud Factory and TractionConf.io. Bizzabo helps us manage the entire customer relationship from the the time they hit our ticketing site (you can build a site with Bizzabo) to buying a ticket (using Bizzabo) to retargeting (Bizzabo enables you to email those who started registering but dropped off - retargeting has provided us with over 50% conversion rate!) to check-in to continuous engagement before, during and after the event (via Bizzabo app, CRM, email). Their customer service is second to none and I haven't found another ticketing provider on the market that enables you to manage the entire value chain for the ticket holder. Overall, Bizzabo is a complete ticketing solution and has been a great experience for us.
