Customer Data Platform
Also: CDP, Customer Data Platforms, Plateforme de données client, Plateforme de données clients, Kundendatenplattform, Customer-Data-Platform
Software that unifies customer data from every source into one persistent profile that marketing, sales and service teams can act on.
What It Is
A Customer Data Platform (CDP) is packaged software that collects customer data from every touchpoint (website, mobile app, CRM, point of sale, email, support desk) and stitches it into a single, persistent profile per person. Unlike a warehouse built by engineers for analysts, a CDP is designed to be owned by marketing and controlled without writing code. The output is a unified view that other tools can use in real time.
Why it matters
Most companies hold rich customer data, but it sits in disconnected systems that never agree on who the customer is. A CMO who wants to stop emailing a discount to someone who bought yesterday needs those systems to share one truth. A CDP turns scattered records into decisions: which audience to target, which message to suppress, which high-value customer to route to a human. For a CFO, it reduces wasted media spend and duplicated licences. For a CDO, it becomes the operational layer where governance and consent rules are actually enforced, not just documented.
How it works
The CDP ingests data through connectors and APIs, then performs identity resolution: matching an email, a cookie, a phone number and a loyalty ID to the same real person. It builds and maintains profiles, lets teams define segments (for example, "lapsed customers who browsed premium products twice"), and pushes those segments to activation channels like ad platforms, email tools and websites. In practice a marketer builds an audience in the CDP interface and it appears in the ad platform minutes later, without a data request ticket. Consent flags travel with the profile, so a customer who opted out is excluded everywhere. Modern CDPs increasingly read from and write back to a central data store rather than copying data, which keeps one governed source of truth.
Frequently asked questions
What is a Customer Data Platform?
A Customer Data Platform (CDP) is packaged software that collects customer data from every touchpoint (website, mobile app, CRM, point of sale, email, support desk) and stitches it into one persistent profile per person. The result is a unified customer view that other tools can use in real time, built to be owned by marketing rather than by engineering.
What is the difference between a CDP and a data warehouse?
A data warehouse is built by engineers for analysts; a CDP is designed to be controlled by marketing without writing code. The warehouse stores and models data for analysis, while the CDP resolves identities, maintains profiles and pushes audiences straight into activation channels. Modern CDPs increasingly read from and write back to a central data store instead of copying it, which keeps one governed source of truth.
Who in the leadership team actually uses a CDP?
A CDP is primarily a CMO and CDO tool. The CMO uses it to target, suppress and personalise without filing a data request; the CDO uses it as the operational layer where governance and consent rules are enforced rather than merely documented. The CFO sees the effect indirectly, through less wasted media spend and fewer duplicated licences.
How does identity resolution work in a CDP?
Identity resolution matches an email, a cookie, a phone number and a loyalty ID to the same real person, then merges those records into one profile. The CDP ingests the raw data through connectors and APIs first, then maintains the resolved profile over time as new signals arrive. Without this step, the same customer stays split across systems that never agree on who they are.
How does a CDP handle customer consent across channels?
Consent flags travel with the unified profile, so a customer who opted out is excluded everywhere rather than in one tool at a time. Because segments are built on that same profile and pushed to ad platforms, email tools and websites, the opt-out follows the person into every activation channel. This is what makes the CDP an enforcement point for governance, not just a record of it.
