A resolved Deep Sync customer identity

Stop guessing
who your customer is.

Most customer identity includes fragmented signals dressed up as people. Deep Sync resolves data deterministically across every device, channel, and household, so you can market to who's actually there.

The answer

From raw data to real customers, with one identity.

The proof

Built to be measured.

Every number is defensible, measured and re-tested quarterly. Speed without accuracy is noise; accuracy without speed is too late. We refuse to trade either.

Why Deep Sync

Three reasons our clients stop guessing.

Three commitments to every customer, set in writing. What you can expect for every audience, every file, every match, and every activation, whether you're running one campaign or building your entire identity stack on Deep Sync.

The accuracy pillar

Most identity solutions guess. Deep Sync knows. Our deterministic identity approach delivers the accuracy modern marketing depends on, making every match, audience, activation, and measurement more accurate from the start.

What that means

  • Real people, real households, real connections
  • Up to 99% accuracy on first-party PII matches
  • 5,500+ individual- and household-level attributes across datasets
  • Truth optimized over scale, by design
The speed pillar

Speed without accuracy is noise. Accuracy without speed is too late. Deep Sync delivers both: deterministic identity and AI-powered workflows that move audiences from onboarding to activation across today's leading platforms, fast and without operational complexity.

Built for modern teams

  • AI-driven workflows
  • Hundreds of marketing and CTV activation endpoints
  • Self-service audience platform
  • Match tests delivered in days, not weeks
The trust pillar

Privacy isn't a feature we added later; it's a foundational principle that has shaped how Deep Sync operates. We prove that knowing your customer and protecting their data can, and should, happen together.
