Lean Canvas

This walks you through Ash Maurya's Lean Canvas framework, the one-page business model tool from "Running Lean" that strips Business Model Canvas down to what startups actually need to test. It guides you through all nine boxes in order (customer segments, problem, solution, unfair advantage, etc.) with specific prompts for each section and helps you identify your riskiest assumptions so you know what to validate first. The skill includes the actual canvas layout and box-by-box instructions with practical tips like "if existing alternatives work well, your problem isn't painful enough." Useful when you're starting something new, preparing investor pitches, or deciding between pivots and need to document hypotheses instead of writing a 60-page plan that's really just a guess.

Methodology Foundation

Aspect	Details
Source	Ash Maurya - "Running Lean" (2012), adapted from Osterwalder's Business Model Canvas
Core Principle	"Document your Plan A, identify the riskiest parts, and systematically test them."
Why This Matters	A business plan is a 60-page guess. A Lean Canvas is a 1-page hypothesis you can test in weeks, not months. It replaces planning with learning.
