From Freeman, one of the largest players in all aspects of the conferences, events and exhibitions arena, this all-in-one module based SwasS based (Software with a Service) platform comes in two flavors one for smaller/shorter events and a Pro version for larger conferences and tradeshows. 

Flexible, but multi-capable, there’s no limit on the number of attendees they can accommodate and no limitation on the number of concurrent sessions that can be held. Organizers can create a homepage with 8+ customizable modules, sponsor material can be displayed and out featured sessions, speakers and exhibitors can be displayed. Its CMS serves as a repository where speakers and exhibitors can upload content. To maximize networking, you can launch a pre-event site. Pricing is based per module and its complexity, rather than per attendee. Show support includes 5-7 quality assurance leads. For more information and case studies.
