Their base product is bringing in $5/month/user, and they'll often get dozens to hundreds to thousands of users for each company that joins, whose employees are usually already using the free version of slack, as a sort of grassroots movement within companies. It's been the primary means of asynchronous communication for the last ~5 customers I've worked at, and I've been in slack channels of 30 to 300 users - in total, an easy 500 paid accounts, and that's just from my network.

Anyway yeah it's a risky investment and a precarious valuation, there is plenty of competition out there right now, yet somehow nothing seems to be able to come out as better than Slack. Maybe if a party actually spent those millions in investment funds to create good non-Electron apps.

One of my Slack channels (not servers, no idea how many are on this workspace) has, no exaggeration, ~45k users. It's a hosted FOSS project so they're not making money on those users, though. I'm curious what the largest Slack instance is if it's not k8s.
