Background of Service Launch Against the backdrop of recent inflation and the Nikkei Stock Average reaching new highs, interest in investment is growing, broadening the base of investors. This situation presents an excellent opportunity for many companies to widely promote their appeal and acquire new shareholders. However, many IR personnel face challenges in communicating effectively to individual investors, such as limited opportunities for effective information dissemination or a tendency towards information that lacks objectivity.

Therefore, by providing a corporate video production and distribution service, the Company aims to enable companies to disseminate information from the perspective of individual investors, while simultaneously providing valuable information to individual investors, thereby creating opportunities for mutually beneficial information exchange.
