Cardboard is a collaborative tool for creating and using Story Maps. It is a virtual home for teams that like to organize by story maps, but can't always share the same wall. Think of Cardboard as your virtual home for those sticky notes.
Create an account and you'll be able to create maps right away. You'll be dragging maps, collaborating with your colleagues, and creating amazing products in minutes. Then you can slice it up into different features and releases.
There's more than one way to succeed so consider lots of them. Slice your product's story into minimal viable product releases and even smaller experiments to test your thinking in the real world. Now you're set up for delivery.
