A customer-data platform, or CDP, is a type of software that is used to collect, integrate, and manage customer data from multiple sources. CDPs are typically used by businesses to gain a better understanding of their customers and to personalize their marketing and advertising efforts.

CDPs allow businesses to collect data from a variety of sources, including websites, mobile apps, social media, and CRM systems. This data is then integrated and organized into a single, unified view of the customer. This can include things like customer demographics, preferences, behaviors, and other data points.

Once the data is collected and organized, CDPs can be used to analyze the data and gain insights into the customer base. This can help businesses to better understand their customers and to tailor their marketing and advertising efforts to specific segments of the customer base.

Overall, CDPs are a valuable tool for businesses that want to improve their understanding of their customers and to personalize their marketing and advertising efforts.
