Learn more about our scoring methodology
Identity resolution and data enrichment platforms unify disparate customer identifiers and events into persistent profiles, then append third-party or inferred attributes (demographics, households, intent, risk, propensity) to make those profiles usable across analytics, activation, and measurement. For marketers, this underpins audience definition, personalization, frequency management, and attribution in a privacy-constrained, multi-channel environment where cookies and device IDs are fragmented. Core capabilities include deterministic and probabilistic matching, graph management, survivorship rules, golden record creation, and controlled enrichment from curated data sources, with governance features for consent, PII handling, and data residency.

Identity Resolution & Data Enrichment platforms are most commonly deployed in Retail & E-commerce, Financial Services & Banking, Healthcare & Life Sciences, and Automotive, based on the published industry focus of vendors in this category.
Each platform receives a composite score from 0 to 100, weighted across four dimensions: Innovation Index, Organizational Strength, Customer Signals, and Vision Index. Scores are recalculated regularly from public evidence and are explained in detail on the methodology page.
Start by matching capabilities to your top use cases, then compare the leading vendors by composite score, customer signals, and industry fit. Reltio currently ranks first in the Identity Resolution & Data Enrichment category, but the right platform depends on your scale, region, and existing tech stack.
