The Lean Canvas is one-page business model that is quite quick to create. It begins with the problem, a proposed solution, the channels to achieving the solution, costs involved and the anticipated revenue streams. The Lean Canvas provides a step-by-step problem-solution oriented approach, which is where to start before developing any idea.

Ash Maurya created the Lean Canvas because business plans take too long to write, are seldom updated, and almost never read by others and do not document your hypotheses, whereas this is key to a scalable, repeatable and sustainable business model.

The Lean Canvas is portable (one page) and easy to share with others, concise as it helps you distill the essence of your product and effective to document and communicate your progress.
