Product Blueprint PredictShield — a real-time regulatory compliance layer for prediction market operators that geo-fences users, classifies contract types against state gambling statutes, and generates audit-ready legal exposure reports by jurisdiction.

Go-to-market Cold-email the compliance and legal contacts at the 8 platforms named in state AG actions in the last 12 months; offer a free 30-day exposure audit for their live contract catalog as the MVP deliverable. First paid product is a $2,500/month API that flags new contracts pre-launch as high/medium/low risk by state before they go live.
