I remember at Uber we had tried Slack for a few months and it could not scale to that number of employees (at the time around 5000 worldwide)...

Doesn’t Uber use Mattermost these days?

yes they have their own internal chat app now this was a few years ago
When was this? Given the number of enterprise customers they claim to have, it is unlikely that Slack can't scale to 5000 users at a company.
