It looks cool. Can kantree import your Trello boards? I think if it can, then it could be a viable alternative. Otherwise, I think heavy Trello users might be too locked into trello to switch.

Yes, you can import boards from Trello and Asana. There's a link to https://kantree.io/import/ at the bottom of your dashboard.
