Identity Resolution
Your customer data tells a hundred different stories about the same person.
We help you find the truth.
Every system in your organization knows something about your customers — but rarely the same things, rarely formatted the same way, and rarely connected to records in other systems. The result is fractured profiles, duplicate records, conflicting data, and business decisions made on an incomplete picture. Identity resolution creates a single, authoritative view of each customer by intelligently linking records across every channel, device, and system they have ever touched.
Identity Fragmentation
When your CRM, marketing platform, e-commerce system, and support tools each hold a different version of the same customer, every team is operating from a different truth, and that costs you in personalization, retention, and revenue.
Data Connectivity
Organizations are investing heavily in first-party data as third-party cookies disappear. But disconnected first-party data spread across siloed systems is only marginally more useful than no data at all, the value is in the connections, not the collection.
Living Infrastructure
Identity resolution isn't a one-time data cleansing exercise. It's a living infrastructure that keeps matching new records, resolving conflicts, and keeping your customer view accurate as data comes in from every touchpoint every day.
Our Strategic Roadmap to Implementation
Effective identity resolution requires far more than a matching algorithm. To succeed, you need a clear understanding of how identity is fragmented, a strategy tailored to your use cases, and governance that keeps the unified view accurate long after the initial build is complete. Our four-phase approach delivers it all.
Identity Audit & Data Discovery
Understand the full scope of how customer identity is fragmented across your organization.
Before any matching logic is built, we need to understand the landscape of customer data as it actually exists, not as it was designed to exist. We map every system that holds customer records, document the identifiers each uses, and measure the scope of duplication, fragmentation, and conflict across your data estate. Most organizations are surprised by what this reveals: the same customer appearing dozens of times across systems with slightly different names, mismatched email addresses, and conflicting transaction histories. This audit becomes the blueprint for the entire resolution strategy.
System Catalog
Map every database, CRM, and platform holding customer identity data.
Duplication Audit
Quantify duplicate and conflicting records before any matching logic is written.
Identifier Inventory
Assess all identity signals, email, phone, and device ID for quality and coverage.
Matching Strategy & Rules Design
Design a resolution approach calibrated to the real cost of getting a match wrong.
Identity resolution sits on a spectrum between deterministic and probabilistic matching, and where your strategy operates depends entirely on your use cases and the consequences of error. Merging two customers who are actually different people is a very different kind of mistake than failing to link two records that belong to the same person. We design matching strategies calibrated to this reality: deterministic rules for high-stakes decisions, probabilistic inference where some tolerance for error exists, and conflict resolution logic that produces a trustworthy golden record every time.
Confidence Thresholds
Set match criteria to the stakes of each use case.
Conflict Rules
Define which source wins on contradictory field values so golden records are always logic-driven.
Survivorship Logic
Select which attribute version enters the unified profile based on source trust and recency.
Identity Graph Construction & Integration
Build the identity graph that connects your customer data across every touchpoint and channel.
The identity graph is the operational core of identity resolution, the structure that links records, maintains confidence scores, stores match evidence, and surfaces the unified profile to every system that needs it. We build identity graphs designed for production scale: handling real-time record ingestion, resolving matches as new data arrives, and exposing unified identity data through APIs and pipelines that downstream systems can consume without friction. Privacy and consent management are embedded in the architecture from the start, not added as an afterthought when regulators ask.
Real-Time Ingestion
Resolve new records as they arrive, not on a batch schedule.
API Exposure
Deliver resolved identity data through stable, well-documented interfaces.
Privacy Controls
Embed consent flags and erasure capabilities so compliance is enforced automatically.
Validation, Governance & Ongoing Maintenance
An identity graph you don’t actively maintain will drift back toward fragmentation.
Identity resolution is not complete at launch. Customer data changes constantly, people move, change email addresses, open new accounts, and interact through new channels. Without ongoing maintenance, the unified profiles that were accurate on day one gradually become unreliable as unmatched records accumulate and existing matches go stale. We implement validation frameworks that measure match quality continuously, governance processes that handle disputed and edge-case records, and update pipelines that keep the identity graph current as your customer data evolves.
Match Monitoring
Track precision and recall in production so degradation is caught early.
Dispute Ownership
Define escalation paths for records that fall below confidence thresholds.
Continuous Updates
Re-evaluate matches as new data arrives so profiles stay current.
