More organised than Trello, MUCH lighter than Asana/Jira/etc
You need to know which parts to use, e.g. we tried the "Workspace" feature but that's clearly designed for bigger teams, not us.
My team switch to Flow a few months ago and we've been really enjoying it. Coming from Trello after it got a little bloated with all our process on top of the simple lists, this was just enough organisation on top to get things going again. I really recommend it for small teams.
