CRM software is a tool sales, marketing, and customer success teams use to manage customer interactions. It's used primarily for sales processes and automations. Although it's a source of customer data, it is only a source of certain types. CDP is an integrated platform that combines data from an organization's software tools to create a single view of the customer. CRM (among other tools) would feed information into a CDP, and the CDP would analyze it next to other data points, such as website visits and purchase history.
