Sven here, another South African in the community!
I work for a small company called Participate Technologies. We have been specialising in Audience Response Technologies in Sub and Southern Africa for close to 15 years.
Currently, we use Wonder in conjunction with EventMobi, in creating Virtual Events and Conferences for all sorts of clients. Wonder has become the single item that most events are lacking, in that it brings natural conference breaks back into the virtual space.
Looking forward to what lies ahead!
