This document introduces the Startup Founder Canvas, a tool created by Michel Cezon to help startup founders explore why they are starting their business and how they will execute their vision. The canvas guides founders through questions in 12 blocks related to their values, motivations, skills, and definition of success. It is meant to be used alongside the Business Model Canvas to assess a startup's business potential and team compatibility. Filling out the canvas individually and then comparing as a group can help founders ensure their goals and approaches are aligned from the early stages.
