I jumped on this and bought three codes even though I suspect I will never get 7500 registrants. I've been experimenting with this and set up up a test summit to check out all the functionality. I'm really looking at running a number of summits in 2020 and this looks to be a much better alternative than trying markets and string together multiple back-to-back webinars in one day. While they officially support Zoom, BigMarker and LiveWebinar (former AppSumo deal!), if you dig into their support pages, they offer solutions for connecting to pretty much any other webinar software you can think of, including things like WebinarJam, which is what I mainly use. I had a bit of a glitch getting connected to LiveWebinar, but the support team got on it even in the middle of the night and we got the problem solved. Great responsiveness! I think I am going to partake of the $10/month upgrade for no transaction fees. I ran the numbers and, if you are doing paid summits, you break even really fast on that deal, so it makes a lot of sense and I appreciate their extending that offer, especially when you see what the normal costs would be. If you are looking at doing online summits, I think this is a great deal and would not hesitate to pull the trigger.
