TourGraph started as AI-powered supply-side infrastructure for the tours & experiences industry. After competitive validation revealed that Peek, TourRadar, Magpie, and Expedia had all shipped live MCP servers, the original thesis was killed and the project pivoted to this consumer experience. The Phase 0 extraction work (83 products, 7 operators, 95% accuracy) is preserved in archive/ for reference.
