Rooted in Data & Building the Future

Used by thousands of clients in the U.S. to power Identity Resolution and Marketing to real-world individuals and households, Deep Sync has been building privacy-safe audiences–not reliant on third-party cookies–for more than 35 years.

We resolve billions of online identifiers to deterministically linked known consumer profiles and integrate with leading cloud environments, data marketplaces, and digital platforms.

How Deep Sync Stands Out Among Today’s Identity Solutions

Deep Sync’s Identity Graph is built from the ground up on a framework of direct mail-grade personal information for real-world individuals and households using persistent identifiers that move with consumers’ life events.

  • Name and postal address coverage for more than 260 million U.S. consumers age 18 and older
  • Offline-to-online identifiers are connected deterministically, based on observed PII linkages for accuracy and stability
  • Opt-out requests are accepted across all states and strictly applied, not just where legally required
