What Is a CDP?
A Customer Data Platform (CDP) is a packaged software system that creates a persistent, unified customer database accessible to other systems. CDPs collect first-party data from multiple sources – websites, mobile apps, CRM, email, POS, support tickets, and advertising platforms – then resolve identities across those sources to build a single, comprehensive profile for each customer.
Unlike data warehouses that store historical data for analyst queries, CDPs are designed for real-time activation. They ingest events as they happen (page views, purchases, app opens, email clicks), stitch those events to the correct customer profile using deterministic and probabilistic identity resolution, and make the unified profile available for downstream systems to act on immediately.
The core value of a CDP is breaking down data silos. Marketing, sales, support, and product teams each generate customer data in their own tools, but no single system sees the whole picture. A CDP aggregates all of that data, resolves it to individual identities, and exposes unified profiles and segments that any connected system can consume – enabling personalised experiences across every channel and touchpoint.
