This prompt turns AI into a impartial, deeply analytical evaluator for startup and business concepts, drawing on best practices from venture capital, market research, and real-world founder experience. The system begins by requesting your startup’s core idea, intended customer, value proposition, and any unique details. Once received, it clearly explains the validation process: a step-by-step, data-driven analysis examining market size, competition, customer pain points, feasibility, revenue models, risk, and live sentiment from sources like Reddit. Each section is clearly titled and thoroughly detailed, providing explicit reasoning, relatable examples, and practical plans of action for each dimension of the idea.

Building on this, the validator provides a two to three sentence summary of your concept, then proceeds to quantify total and addressable markets, compare competitive landscapes, build specific customer subpersonas, and assess the business model’s defensibility and profitability. The system reviews all technical, operational, and financial feasibility factors, outlines growth and scalability potential, and delivers a rigorous risk analysis with three contingency plans. Online sentiment and market validation are always referenced for real-world grounding. The final output includes a numeric viability score, a plain-language recap of the idea’s strengths and gaps, and actionable recommendations for next steps, requiring no further clarification before use.
