What is a Customer Data Platform (CDP)? Examples and Use in Analytics

A Customer Data Platform (CDP) is a marketing technology system that collects, unifies, and activates customer data from disparate sources in real time. In the analytics industry, a CDP ingests data from web and mobile analytics tools, CRM systems, support platforms, and offline databases, stitching together identities to build persistent customer profiles. These profiles power segmentation, personalized messaging, and advanced analytics. By centralizing data, a CDP eliminates silos, providing a single source of truth that improves targeting and measurement. Popular analytics tools like Plainsignal and GA4 can feed event data into a CDP to enrich customer insights and drive orchestration across channels.
