DMP DC catalyzer is a public DMP that combines various external data and functions as a "catalyst" that reveals insights. The public DMP "DC Catalyzer" developed by Data Chemistry combines and stores various external data such as approximately one million "TV viewing log data", "web media behavior logs", and "awareness surveys". By linking this public DMP with the company's customer information data and private DMP, not only existing customers but also potential customers with high prospects will emerge. In addition, "DC Catalyzer" works smoothly with external media, making an appropriate approach to prospective customers and demonstrating its power in subsequent effect measurement. Data Chemistry combines vast amounts of data and approaches consumer insights in a way that induces chemical reactions. As the name suggests, the public DMP "DC Catalyzer" that we have developed and continues to nurture will contribute to corporate communication and management as a "catalyst".
