To work along side them, we are really just thinking about the collaborative decision making bit. We do have document editing built-in (WYSIWYG markdown editing), but issue trackers for example, backlogs, kanbans would still be in place for _doing_ work. I can imagine replacing Slack, for the right team. We are a small team, but internally we use our own app (all the time) plus Google Chat (rarely, for quick pings).
