Split high level canvas into narrower canvases
Sketching out a Lean Canvas quickly is a great first step for taking stock of your big idea and visualizing your business model as a set of assumptions. That said, most entrepreneurs either go too broad or too narrow with their first canvases. This is a Goldilocks problem.
