PLAID Centralizes Customer Data Platforms Across Seven KOSE E-Commerce Sites to Support Comprehensive Data Utilization

PLAID Inc. (Chuo-ku, Tokyo; CEO Kenta Kurahashi) has announced an expanded partnership with KOSE Corporation (Chuo-ku, Tokyo; President Shinji Tanaka). Following the successful implementation of the KARTE CX platform for KOSE's flagship brand "DECORTÉ," PLAID is now integrating customer data platforms (CDP) for six additional e-commerce sites. This initiative provides comprehensive support for data utilization, enabling KOSE to transition towards customer-centric marketing and corporate activities.

The project leverages the KARTE product suite alongside "PLAID ALPHA," a professional service division that provides technical implementation and operational support. By combining advanced product technology with human expertise, PLAID aims to drive the project forward from both a technical and strategic perspective.

### Background: Achieving the "Your Lifelong Beauty Partner" Vision The cosmetics market is currently navigating significant environmental shifts, including diversifying consumer needs, fragmented cognitive channels in promotion, and global economic pressures. To achieve sustainable growth, companies must understand the true needs of all customers—from first-time buyers to long-term loyalists—across all sales channels, including physical stores, wholesale, and e-commerce.

Large beauty enterprises often face challenges where customer data is siloed within brand-specific systems. To resolve this fragmentation, KOSE has implemented the KARTE series across five additional brands—"JILL STUART Beauty," "ADDICTION," "SEKKISEI," "MAIHA DA," and "ONE BY KOSÉ"—as well as the multi-brand site "Maison KOSÉ." Utilizing the unified KOSÉ ID infrastructure, these sites can now provide high-resolution customer experiences. PLAID ALPHA provides the specialized support needed to link the CDP with KARTE and assists in executing site-specific strategies.

### Executive Statement from KOSE Yu Shiotani, Manager of the Direct Business Office at KOSE Cosmetics Sales, commented: "To realize our goal of being a 'Your Lifelong Beauty Partner,' we must provide a sophisticated digital customer experience that reflects our brands' prestige. This initiative establishes the foundation for each site to deliver ideal experiences. By fusing KARTE’s technology with professional insights, we will pursue a consistent experience across stores and e-commerce, creating new value through digital innovation."
