I just tried and I really like the concept. I think this tool can add great value to collaborative teams.
When it comes to the setup, it was an easy onboarding process. If I may give small feedback: I would love to see more "overview" cards. For example in Asana, I didn't have the option to add a card to show my today's to-do list. I had to choose a specific project for each card. It's not the end of the world, as there is great value to see an overview of all ongoing projects on the same screen, but having both options would be nice.
Good luck and I'll keep following this product to see its development!
