Why Identity Resolution matters

Connect every touchpoint to one customer profile

Link fragmented IDs across every channel so you recognize customers everywhere they shop. Stop sending duplicate emails to your regulars.

Find your hidden high-value customers

Consolidate fragmented profiles to reveal true lifetime value. Give your biggest spenders the VIP treatment they've earned.

Stop duplicate marketing spend

Cut duplicate emails, redundant ads, and wasted catalog sends. When you merge duplicate profiles, every marketing dollar reaches a real person.

Maintain customer trust and privacy

Link consent decisions across channels to the right customer profile every time. When Jane Smith becomes J. Smith, her opt-out preferences follow her. Avoid regulatory fines and maintain customer trust through unified consent tracking.

AI-powered identity resolution

Build unified profiles in hours, not months

There are three approaches to identity resolution. Manual SQL matching requires data engineering teams and breaks constantly. Deterministic rule-based tools deliver high precision but miss 40%+ of matches. Amperity's AI/ML approach combines deterministic confidence with probabilistic discovery, capturing what others miss.

Flexible identity matching: run multiple identity graphs

Run multiple identity graphs simultaneously: Growth Graph (probabilistic) maximizes reach, Trust Graph (deterministic) ensures compliance, Opportunity Graph measures the gap between proven and probable matches.

"We almost couldn't believe it — the time that it took us to deduplicate information compared to what Amperity did. And they deduplicated 3x what we had been able to do on our own."
