What problem does it solve? Validating a new product idea before building it is hard, and teams often rely on opinions or secondhand market data instead of real behavioral evidence. This Skill structures lean startup validation by turning a product concept into a testable XYZ hypothesis and concrete low-effort pretotype experiments. ## Core Features & Use Cases - XYZ Hypothesis Creation: Frames the idea as "At least X% of Y will do Z" with a defined target market and engagement action. - Pretotype Experiment Design: Suggests 2-3 low-effort validation methods such as landing pages, explainer videos, email campaigns, pre-orders, or concierge MVPs, each with a metric and success threshold. - Skin-in-the-Game Principles: Applies Alberto Savoia's The Right It principles, prioritizing real commitment (time, money, reputation) and Your Own Data (YODA) over opinions and market reports. - Use Case: A founder with a new app idea asks for validation experiments and receives a measurable hypothesis plus a landing page test and a pre-order campaign, each with clear pass/fail thresholds. ## Quick Start Ask the assistant to design pretotype experiments and an XYZ hypothesis to validate your new product idea, describing the concept and target market.
