What problem does it solve? Startups and product teams waste months building products nobody wants because they execute fixed plans instead of testing assumptions. This Skill applies the Lean Startup methodology to design minimum viable experiments, measure real customer behavior, and make evidence-based pivot-or-persevere decisions before scaling. ## Core Features & Use Cases - MVP Design: Choose and size the right MVP type (concierge, Wizard of Oz, smoke test, single feature, piecemeal) to test your riskiest assumption with the least effort. - Innovation Accounting & Actionable Metrics: Replace vanity metrics with cohort analysis, conversion funnels, and LTV/CAC economics that actually drive decisions. - Pivot or Persevere Decisions: Evaluate ten pivot types (zoom-in, customer segment, platform, engine of growth, and more) against pre-defined criteria and validation evidence. - Use Case: A founder wants to test whether remote teams will pay for an async video tool. The Skill guides them to map leap-of-faith assumptions, run a landing-page smoke test with a 3% signup threshold, and define pivot triggers before writing any code. ## Quick Start Help me design the smallest MVP to test whether small marketing teams will pay $49 per month for AI-generated social media captions, including the hypothesis, success metric, and pivot criteria.
