Let me introduce you to insparcs, it is a simple, flexbible platform working with kanban boards as groups. With different card types on it. We created a super flexible platform for you to create your own card types and groupboard types. So everyone can build their own cards and customize their own groupboards:
Insparcs's unique feature is that a card does not solely belong to one group. It has its own life. Insparcs promotes the idea of bottom-up and networked collaborative swarming together.
