--- name: lean-startup description: Apply Lean Startup principles for hypothesis validation and iterative product development version: 1.0.0 author: wondelai (adapted) platforms: [claude-code, cursor] license: MIT source: https://github.com/wondelai/skills based_on: "The Lean Startup by Eric Ries" --- # Lean Startup Apply validated learning to build products customers actually want. ## Scoring System Rate your product development approach 0-10 on lean principles. Show: current score → assumptions → experiments → metrics. ## Build-Measure-Learn Loop ``` Idea ↓ BUILD ← minimize time to here ↓ Product ↓ MEASURE ← collect actionable metrics ↓ Data ↓ LEARN ← validate/invalidate hypothesis ↓ Pivot or Persevere ``` **The goal is to minimize the total time through the loop.** ## Hypothesis Types ### Leap-of-Faith Assumptions Every product is built on assumptions. State them explicitly: - **Value hypothesis**: Does the product create value for customers? - **Growth hypothesis**: How will the product spread to new customers? Format: ``` We believe [target customer] will [do action] because [reason]. We will know this is true when [measurable outcome]. ``` ## MVP Types (from lowest to highest cost) | MVP Type | Cost | When to use | |----------|------|-------------| | Concierge MVP | Hours | Very early stage, high uncertainty | | Wizard of Oz | Days | Test demand before building automation | | Landing page | Days | Validate interest/signups | | Prototype (Figma) | Days | Validate UX flows | | Fake door | Days | Test feature demand | | Functional MVP | Weeks | Validate full value loop | ## Actionable Metrics vs Vanity Metrics | Vanity | Actionable | |--------|------------| | Total registered users | % active users (7-day) | | Page views | Conversion rate | | Downloads | Retention D1/D7/D30 | | Revenue total | Revenue per customer | | Feature count | Feature adoption rate | Use **cohort analysis** to see if things are improving over time, not just growing. ## Pivot Types - **Zoom-in**: a feature becomes the product - **Zoom-out**: the product becomes a feature of something bigger - **Customer segment**: same problem, different customer - **Customer need**: same customer, different problem - **Platform**: product becomes platform or vice versa - **Business architecture**: high-margin → high-volume or vice versa ## Pivot or Persevere Decision Pivot if: - Experiments are failing to improve metrics - You're building and building but not learning - Conversations with customers keep turning to a different problem
