Demio is one of the most reliable and high quality webinar platforms out there. It is a top webinar provider. Its tight competitor WebinarNinja lost one point in quality of stream with large audiences, otherwise they are pretty much equal. Demio positions itself as the simplest webinar tool for marketers that increases sales and doesn't become your pain in the process. Live streams, broadcasts, replays, private and general chat, branded registration page and many more features. However, they specialize in large live streams, being the best live webinar software.
