Customer Data Platform Basics

A customer data platform (CDP) is packaged software that collects first-party customer data from every source — websites, mobile apps, CRM, email, point-of-sale — and unifies it into persistent profiles that power personalization, analytics, and AI-driven marketing.

Frequently Asked Questions

What is a customer data platform (CDP)?

A CDP is packaged software that collects first-party customer data from every source — websites, mobile apps, CRM, email, point-of-sale — and unifies it into persistent profiles. CDPs power personalization, audience segmentation, analytics, and AI-driven marketing automation. Read the complete guide.

What is the difference between a CDP and a CRM?

A CRM stores known-customer transaction and interaction records entered by sales and support teams. A CDP automatically ingests behavioral, transactional, and anonymous data from all channels, resolves identities across devices, and makes unified profiles available to every downstream tool in real time. See the full comparison.

What are the types of CDPs?

CDPs fall into three architectural generations: Packaged CDPs (first-gen, batch-only), Composable CDPs (warehouse-native with separate tools), and Agentic CDPs (AI agents as primary users, closed feedback loops, bundled CDP+messaging+AI). Learn about the 3-stage CDP evolution.

How much does a CDP cost?

CDP pricing typically ranges from $50,000 to $500,000+ per year depending on data volume, number of sources and destinations, and architecture choice. Composable stacks may have lower licensing fees but higher engineering and infrastructure costs. See how to evaluate vendors.

Do I need a CDP if I already have a data warehouse?

A data warehouse stores data for analytics but lacks built-in identity resolution, real-time profile access, and audience activation. You can build composable CDP features on top of your warehouse using reverse ETL, or deploy a hybrid CDP that connects natively to your warehouse. See CDP vs Data Warehouse.
