Customer data platform (CDP)

A customer data platform is software that collects customer data from multiple sources, websites, apps, CRM, email, point of sale, and merges it into persistent, unified customer profiles that other systems can use, typically for marketing activation such as segmentation, personalization or ad targeting.

A CDP resembles master data management in that both resolve fragmented records into a single view of an entity, but a CDP is generally marketing-owned, optimized for first-party data and built to activate profiles quickly in downstream tools, rather than serving as an enterprise system of record. Some organizations now build CDP-like functionality directly on their data warehouse using Reverse ETL to sync computed profiles and segments out to marketing tools, blurring the line between a packaged CDP and a warehouse-native approach.

CDPs matter for organizations that need consistent customer segmentation and targeting across many channels without each marketing tool maintaining its own incompatible version of the customer. They also support metrics like customer lifetime value that require stitching activity across touchpoints. Common pitfalls include buying a CDP without solving upstream identity resolution and data quality problems it can't fix on its own, and letting profile logic diverge from the definitions already agreed on in the warehouse.
