This tool is for mapping business model assumptions and then systematically validating those assumptions in sprints. Plus, there is rock-solid training videos in context. Pros: Great tool for LEARNING AND PRACTICING lean startup. Rooted in theory + practice. Succinct. Responsive designer. Cons: Less useful if you don't follow time-bound sprints.
