BlueJeans is used throughout our organization to facilitate meetings. We have a very geographically spread out company and our team in particular has members overseas and a generous work from home policy, so not a day goes by when we don't use BlueJeans either at a planned meeting or for spontaneous conversations. Without this, we'd be stuck trying coordinate phone numbers or we'd simply have an issue dealing with people not in our office. It's also extremely simple to use. No software is required (though the desktop application adds functionality) and you just enter a link and go.
