[Glad Cube] Announces Strategic Business Alliance with PLAN-B ~ Strengthening Marketing DX Support System by Integrating Video Customer Service Technology and Content Monetization ~

Glad Cube Inc. (Headquarters: Chuo-ku, Osaka; CEO: Hiroki Kanajima; hereinafter referred to as Glad Cube) has entered into a strategic business alliance with PLAN-B Inc. (Headquarters: Nishi-ku, Osaka; Representative Director: Masanori Torimot; hereinafter referred to as PLAN-B) in the field of marketing support, combining "video customer service" technology with the monetization of influencer videos through secondary use.

With this alliance, starting March 31, 2026 (Tuesday), we will begin offering a performance improvement solution for EC and websites that integrates influencer marketing and website improvement.

Specifically, this solution combines PLAN-B's proposed "Influencer Growth® Model (Content Monetization)" with the "video customer service" technology of Glad Cube's next-generation engagement platform "SiTest Engage." By elevating scattered customer acquisition on social media into a linear purchase experience on websites, we will build a system to support the maximization of Customer Lifetime Value (LTV).

■ Background of the Alliance

Moving Beyond "Set It and Forget It" in a Market Worth Approximately 14.5 Trillion Yen

The domestic creator economy market continues to expand, reaching 2.0894 trillion yen in 2024. Furthermore, when including the potential market for corporate utilization and IP (Intellectual Property) utilization, its scale is estimated to be approximately 14.5 trillion yen (*1). However, many companies face challenges such as "influencer marketing ending with awareness on social media, making it difficult to see its contribution to sales" and "high-quality video content produced being consumed in one-off posts and not fully utilized as assets." Additionally, in website improvement, bottlenecks include "static images not fully conveying product appeal" and "high secondary usage fees for featuring talent or model videos on websites."

In response to these challenges, both companies, with their extensive experience in the digital marketing domain, have partnered to develop a solution that achieves website "videoization and customer service" while controlling costs.

■ Three Value Propositions of This Solution

① Monetization through "Secondary Use" of High-Quality Influencer Videos

PLAN-B's "Cast Me!" and strategic casting will assign influencers best suited for the product. The key feature is that the generated video content can be used "secondarily for free (※conditions apply)." While featuring talent videos on websites typically incurs high additional costs, this scheme allows for cost-effective monetization of "selling videos (UGC-style videos)" that have resonated on social media as customer service content on your own EC site or LP, indefinitely.

② Dramatic Improvement in CVR with "Video Customer Service" Implemented No-Code

Secured video assets will be implemented on the website as "pop-ups" or "picture-in-picture (follow playback at the screen edge)" using Glad Cube's "SiTest Engage" with no-code implementation. By providing an environment where users can "watch while doing" and check actual product usage via video while browsing product pages, we appeal to product appeal that cannot be conveyed by static images alone. Past results include cases where the use of model videos led to a 9.2x increase in dwell time and a 2x improvement in CVR, and cases where the use of influencer videos resulted in a 3x increase in sales compared to the same period last year, indicating expectations for dramatic performance improvements.

③ From "Point" Measures to a "Line" CX Improvement Platform

This solution does not end with simply posting videos. Using "SiTest's" heatmap analysis function, we visualize and analyze "where videos were played and where users dropped off." By continuously executing a PDCA cycle based on data, influencer marketing is transformed from one-off promotions into a driver of continuous business growth.

■ Future Developments

With the launch of this solution, we will initially focus on providing implementation support and accumulating success stories by leveraging both companies' customer bases. Moving forward, based on operational feedback, we will further deepen the technology of "SiTest Engage" and PLAN-B's expertise, aiming to establish video asset utilization as a new standard in marketing DX. By maximizing business synergy through the combination of both companies' strengths, we aim to achieve sustainable corporate value improvement and market share expansion.
