Customer data platform (CDP)
Also known as: CDP
In short
A customer data platform (CDP) is software that gathers customer and prospect data from websites, apps, email, and other systems, resolves it into one profile per person, and shares those profiles with other tools. The point is a single, consistent view of each customer.
CDPs came from consumer marketing, where identity and behavior across channels matter most. In B2B they are used to join person-level activity with account-level context.
What a CDP does
- Collect: Ingests events and records from web, product, CRM, support, and ad tools.
- Unify: Matches records using identifiers such as email and device IDs to build one profile.
- Segment: Builds audiences from traits and behavior.
- Activate: Sends audiences and profiles to marketing, sales, and ad tools.
CDP versus CRM and data warehouse
Some teams now run a CDP-like setup on top of their warehouse instead of buying a separate product. The decision depends on volume, engineering resources, and how fast marketers need self-serve audiences.
- CRM: Stores sales relationships and deals. Reps work in it daily.
- Data warehouse: Stores raw and modeled data for analysis. It is built for analysts and engineers.
- CDP: Builds unified profiles and pushes them to activation tools. It is built for marketers and operations.
B2B considerations
B2B buying involves several people per company, so profiles must roll up to accounts. Look for support for account-level identity, not only individual profiles. Consent and privacy controls matter too, and general rules vary by region; this is not legal advice.
An example
Say a visitor reads pricing pages, opens two emails, and later fills in a form. A CDP merges these into one profile, tags it with the company, and sends the audience to the ad platform and the CRM, so sales sees the activity and ads stop targeting people already in a deal.
Common mistakes
- Buying before defining use cases: Pick two or three activation goals first.
- Poor identity rules: Loose matching merges different people into one profile.
- Dirty inputs: A CDP unifies data; it does not fix bad data.
Customer data platform (CDP) FAQs
What is a customer data platform (CDP)?
A customer data platform is software that collects customer data from many sources, merges it into one profile per person, and sends those profiles to other marketing, sales, and analytics tools for segmentation and personalization.
What is the difference between a CDP and a CRM?
A CRM manages sales relationships, deals, and rep activity. A CDP unifies behavioral and identity data from many systems into profiles and activates them across channels. They often work together, with the CRM as one input.
What is the difference between a CDP and a data warehouse?
A data warehouse stores large volumes of raw and modeled data mainly for analysts. A CDP focuses on identity resolution and on pushing unified profiles and audiences to marketing and sales tools, usually with a non-technical interface.
Does a B2B company need a customer data platform?
Not always. It helps when customer data is spread across many tools and teams need unified audiences. Smaller teams may be served by a CRM plus marketing automation, or by activating directly from a data warehouse.
