  "title": "SkillSwap",
  "problem": "Remote workers have skills they could exchange (a designer who needs a quick legal opinion; a lawyer who wants design help with a deck) but no good marketplace for non-cash skill trades. Cash marketplaces (Fiverr, Upwork) introduce a money layer that kills casual exchange.",
  "targetUser": "Remote knowledge workers, 25–45, who value reciprocal exchange over hiring out and have at least one marketable skill outside their day job.",
  "desiredOutcome": "Two strangers complete a skill swap end-to-end (matched, scoped, exchanged, both rated positively) within one week of joining.",
  "initialHypothesis": "A two-sided marketplace works for skill swap if matching is high-trust (reputation portable from LinkedIn) and scope is bounded (max 2-hour exchanges, no open-ended retainers).",
  "constraints": [
    "No money changes hands inside the platform",
    "Identity verification via LinkedIn or similar at signup",
    "Disputes capped to mediator review — no chargeback equivalent"
