Launch Week: SnapStudy — From Idea to First Dollar

US high-school entrepreneurship simulation. Teams of teen founders take SnapStudy (a direct-to-consumer focus-timer + flashcard kit) from validated idea to first paying customer in four rounds: customer discovery and MVP scoping, pricing and unit economics, launch day, and pivot-or-persevere after real data. Every number is US-defensible in 2025 — Shopify Basic $39/mo, Stripe 2.9% + 30¢, Ohio LLC $99, Amazon FBA $3.97/unit, South Dakota v. Wayfair economic-nexus thresholds, COPPA compliance. Frameworks: Steve Blank Customer Development, Eric Ries Lean Startup (Build-Measure-Learn + 7 pivot types), Osterwalder Business Model Canvas, David Skok unit economics, Sarasvathy Effectuation.
