CommPartners' MediaCenter for Conferences
We have used MediaCenter for 4 virtual conferences - the first one was thrown together in 6 weeks in 2020. Since we already use their LMS, Elevate, it was so easy for me to use with no learning curve. CommPartners' staff was very helpful with set up and the pre-show prep. I have not considered looking at other vendors.
My only concern is we had their producers host our sessions in their streaming plaform and some of the producers were "better" than others - with strong consistency in guiding the speakers through the run of show and confirming our instructions.
I highly recommend CommPartners platforms in general.
