Master the key distinctions between data brokers and data providers with plain-English definitions, practical classification rules, and actionable insights for navigating today's complex data ecosystem.
A company whose core business is collecting, aggregating, and selling or licensing data about people or organizations to third parties—often without a direct relationship with the data subjects (e.g., people-search sites, marketing/advertising audience sellers, list/append vendors).
A company that originates data (from its own users, devices, transactions, sensors, research, or operations) and licenses or exposes it (files/APIs/feeds) for analytics or integration. The focus is on producing data products, not necessarily trading third-party personal data.
A side-by-side comparison of data providers and data brokers to help you understand their distinct roles in the data ecosystem.
