Background of KUZEN's Second Consecutive Award

Against the backdrop of stricter regulations on third-party cookies and growing privacy awareness, companies are being challenged to leverage their own data. During this transitional period, interest in KUZEN, which has a track record of supporting the utilization of first-party data centered around LINE, has further increased, leading to this second consecutive award. Moreover, as demand grows for direct contributions to sales and LTV improvement beyond simple "message delivery," KUZEN's features and support system, which realize "LINE marketing that commits to results," have garnered support from many companies across various industries.

1. Utilization of 1st Party Data to "Generate Sales"

There is continued high interest in personalized experience design, such as delivery based on user attributes and segmentation of rich menus, by integrating with customer databases (CRM). The approach of increasing engagement by utilizing "first-party data" owned by the company, without relying on cookies, is attracting the attention of many marketers.

2. Expectations for Features Directly Linked to Performance Improvement

Features that can deliver results immediately after implementation, such as "real-time reminder delivery to prevent cart abandonment on e-commerce sites," remarketing delivery based on web browsing behavior, and step-by-step delivery linked to actions like store visits, purchases, and adding friends, continue to be highly evaluated. The reason for support from many companies across industries is not just the provision of tools, but their functionality that can directly contribute to business KPIs (sales and LTV improvement).

3. Building a System Capable of Achieving Results Regardless of Resources Through Generative AI x Collaborative Support

Based on vast accumulated data, generative AI analyzes customer insights and automatically determines the optimal content, timing, and channel for each individual, executing personalized communication. This significantly reduces the operational burden on marketing staff. Furthermore, beyond just providing tools, we have established a comprehensive support system that accompanies clients from strategy planning, scenario building, and creative production to performance verification. The expertise accumulated through the diverse adoption by over 700 companies, from small and medium-sized enterprises without dedicated internal staff to large corporations deploying large-scale initiatives, supports the quality of our assistance and is a strength that has led to two consecutive awards.
