For researchers & private buyers
Academics, journalists, and independent researchers with a legitimate, certified purpose can access consented data segments — provenance attached, nothing acquired in the dark.
For institutions
Brokers, marketers, and platforms can source consented, quality-scored tranches with full economic context — the most defensible data supply chain in the market.
The Firm
For too long, individuals have surrendered their data without recompense, and institutions have acquired it without provenance. We founded User Data Market to correct both failures at once.
Every transaction on our exchange is consented, audited, and settled under a single standard of care. We act as steward to the seller and as counsel to the buyer — never as a broker indifferent to either.
Services
Sovereign-grade custody for first-party datasets, with cryptographic provenance and consent records held to fiduciary standard.
Direct, transparent access to a vetted network of institutional buyers, with negotiated terms and full price discovery.
Continuous oversight across jurisdictions, ensuring every disposition is lawful, consented, and defensible on audit.
