ProvenanceX

ProvenanceX is a web + mobile app that helps collectors and dealers assemble, verify, and share provenance dossiers for luxury collectibles (art, watches, jewelry, rare books). Users upload invoices, auction results, service records, photos, and certificates; the app extracts key fields, flags inconsistencies, and produces a clean “sale-ready” dossier link for buyers, insurers, or auction houses. It also tracks chain-of-custody events (service, appraisal, transfer) with tamper-evident logs and optional third-party verification (appraisers, authorized service centers). This is not a magic authenticity detector—it's a practical paperwork and trust layer that reduces friction in private sales and insurance claims. Monetization is subscription for collectors/dealers plus per-dossier verification fees. The product wins by being boringly reliable, faster than manual admin, and acceptable to professionals who already live in PDFs and email threads.
