I'm user of Session Us and 3 Veta but honestly this is such a great tool. No need to run a meeting in Zoom or MS Team or if you want no problem....But Dive has its own video calling and it is really good. No issue! My only problem is how you view a calendar as it is fitted into 1 column. No calendar view like Google Calendar if you wish to see a whole week. But they said "working on it". For Tier 3 you get 100 members which is enough for most of us. They have a lot of apps integrated in Dive (natively or built in) which is such a great addition to it. I would highly recommend to get it while you can and I don't understand why it has only 2 reviews....It should get a way more :)
