STONE.B Co., Ltd. Press Release: September 3, 2025 JSECURITY・GENDA Capital・ZVC・JIRAN JAPAN invests in “mahocast” operating company STONE.B – One-stop platform for Japanese and Korean artist IP, fully embarking on two-way global expansion — Tokyo/Seoul | August 27, 2025 – STONE.B Inc. (hereinafter referred to as STONE.B) announced that it has received investment from JSECURITY Inc., GENDA Capital Inc., Z Venture Capital Inc. (ZVC), and JIRAN JAPAN Inc. for “mahocast,” a one-stop platform for artists operated by the company. (Investment amount and ownership ratio are not disclosed) STONE.B operates a business that provides artists with a single platform for everything from event planning, production, and management to ticket and merchandise sales and fan club management. With this investment, the company aims to further grow as a global hub platform that provides two-way support for artists in both Japan and Korea. The investors stated, “K-POP is a promising field whose market size is expanding along with its global popularity, but it has been difficult for Japanese startups to design a meaningful entry angle.” They also praised STONE.B, saying, “STONE.B is a rare business that can make proposals from the planning stage and provide the entire process of an artist’s activities, including tickets, merchandise, and fan clubs, all in one place.” Furthermore, “In addition to K-POP, there is also a growing need for Japanese artists to enter the Korean and overseas markets,” he said, expressing his hope that “STONE.B will establish itself as a specialized trading company connecting the IP of both countries.” Furthermore, “Given the global popularity of K-POP and J-POP, it is possible to support the overseas expansion of Japanese artists through Korea and other Asian countries, as well as through global tours,” he added, emphasizing that “the consortium will continue to provide full support.” In addition, with this investment, JSECURITY will strengthen the security of the “mahocast” ticket service and create a safe and reliable ticketing environment. Furthermore, the JIRAN Group will provide business support, including its Korean network, to support STONE.B’s business expansion in both the Japanese and Korean markets. STONE.B will actively strengthen overseas marketing for performances held in Japan, going beyond simple ticket sales to serve as a play guide connecting global fans. This will enable Japanese performances to reach not only the domestic market, but also fans in Korea and other parts of Asia and globally at the same time, establishing a win-win system for artists, fans, and investors. In addition, with this investment, we will gradually explore collaboration models with our investors. By doing so, we plan to combine our investor network with STONE.B’s operational know-how to create new opportunities in the IP business and further strengthen our business foundation in the global market.
