I had lunch yesterday with a true pioneer in the conferencing industry, Bruce Frydenlund, COO at EventBuilder. Bruce was the founder of EnvoyGlobal, which was acquired by PlaceWare (later acquired by Microsoft becoming Microsoft Office LiveMeeting). He then founded Encounter Collaborative, now renamed EventBuilder, and continues to provide some innovative solutions.
If you need an easy-to-use registration system that includes e-commerce and simplifies how you take your web seminar recording and get it posted (again with e-commerce), EventBuilder should be on your list to investigate.
Separately, EventBuilder has a system for broadcasting video of local sports events (that could easily apply to many other types of events) that is truly intriguing…and within reach of average budgets. Worth a peek.
