Discord missed an opportunity a year or two ago to become something like slack for large companies. Hipchat's perf is horrible and slack couldn't scale to +20k users a year ago. Managing a mattermost instance requires staff and is more outage prone.
It's really too bad that they didn't take advantage of it, since they were actually scalable compared to their competitors and had good voice chat. Slack has started becoming more scalable recently, so I don't know how much the opportunity is still there.
I think it makes sense for Discord to stick to it's gaming niche, rather than trying to do a bunch of things poorly.
The other market is a bit more saturated, with Microsoft and a few others piling on top too. Whereas the Gaming market was completely lacking. There were a few clients which focused much more on voice (mumble, vent, ts), but nothing quite like Discord. Free and one-button to make a new server.
The only other contender I can think of is Raidcall, but that was a joke... Now there's Curse but they came too late to the market and were DoA, except the people they forced to use it by paying thousands.
We've been using Discord a bunch at our company (HearthSim). We have a server for our user community, one for our open source org and one for our company. It's superb, works so much better than Slack ever could.
Are companies a market you're serious about? There is so much focus on gaming, it's hard to be sure. I mentioned to support recently one of our prime issues as a company is being limited to a single owner per server.
PS: Are you the same Stanislav Vishnevskiy I'm thinking about? I remember working on Guildwork with you!
We currently don't share exact metrics for all those stats, but we have shared a few press releases and blog posts which you can easily extrapolate from. :)
Hipchat goes terribad in a 20k organization . In things like only delivering pushes to your phone sometimes or getting chat room history when you open the app. I dont know how slack performs in a similar situation.
