Customer Data Platform – Definition

A system that collects and unifies customer data from multiple sources to create comprehensive customer profiles.

CDPs aggregate data from websites, mobile apps, CRM, and other sources to provide a 360-degree view of customers. This enables personalized marketing and improved customer experiences. A CDP's core function is identity resolution: recognizing that a visitor browsing anonymously on a phone, a logged-in customer on desktop, and a subscriber opening a marketing email are actually the same person, and unifying their behavior into a single profile. This unification is what makes downstream personalization meaningfully more accurate — targeting rules that can only see fragmented, single-channel data produce coarser, less relevant segments. CDPs differ from traditional CRM systems in an important way: CRM typically centers on known customer records built from direct interactions, while CDPs also incorporate behavioral and anonymous data at much higher volume and velocity, closer to real time.
