A music live-streaming platform company that develops and operates a song-specific live-streaming app. Featuring a vast music distribution environment utilizing JOYSOUND sound sources and a system where rewards can be earned for each performance, the platform provides a music community where singers and listeners connect. It aims to build an ecosystem that expands the entertainment experience centered on singing and maximizes the power of song.

■Business Overview

The company released its song-specific live-streaming app in July 2023. It aims to revolutionize the music domain—where previously only a limited few could succeed—by building an ecosystem where a broader range of singers and peripheral creators can be recognized and earn income. Through this transformation, the company seeks to create a world where people can enjoy music more closely and freely.

With investment and business support from XING Inc. (provider of "JOYSOUND") and DeNA Co., Ltd. (operator of "Pococha," one of Japan's largest live-streaming apps), the company's sales are growing at more than double annually, reaching a scale of 360 million yen in monthly sales.

The organization is built around a small, elite team primarily composed of members with backgrounds in the live-streaming industry. In 2026, backed by solid product quality and a stable business foundation, the company is aiming for even further growth.
