News Release

mui Lab completes fundraising totaling 300 million yen and accelerates to promote calmer smart home experiences that are close to people's hearts

Nov 11, 2022

mui Lab being Japan's first to support "Matter," an innovative international standard for interconnecting smart home devices, further spreading the qualitative smart home experience around the world

mui Lab is pleased to announce that it has raised a total of approximately 300 million yen through a third-party allotment of new shares with Miyako Kyodai Innovation No.2 Investment Limited Partnership as the lead investor and giftee Corporation, Shinshu Startup and Succession Support Investment Limited Partnership, and funds managed by three existing investment companies as the subscribers. The total amount of funds raised will be approximately 300 million yen. Through this fundraising, we will promote active recruitment of key software development personnel in the growing smart home market, as well as alliances with partner companies and aggressive investment in the development of our own products and services.

mui Lab was created as a research and development startup of Calm Technology, headquartered in Kyoto, Japan, and has focused its entry into the "smart home market" on business development. Through partnerships with previous partners, mui Lab has promoted a peaceful smart home experience by developing and delivering the mui platform, a fusion of hardware and software.

To date, mui Lab has won two CES Innovation Awards at the world's largest technology trade show (2019 & 2022) for the mui Board, the world's first wooden smart home controller, as well as the mui Smart Home Platform respectively.

In August 2022, in collaboration with giftee Corporation, the "mui Kurashi application" equipped with a DR (Demand and Response) function that encourages people to save electricity was provided to residents of EFUTE Kita Sanjo, a rental housing project of Kitagas LIFRONT Co. This project is a system in which points are issued to those who cooperate in energy-saving measures. This project is an example of high compatibility between smart home systems and energy management, which creates a comfortable touch point between smart home devices and its users, thereby building an organic relationship between companies and consumers and impacting environmental issues.

In addition, at the release announcement of the international standard "Matter" on November 3, 2022, we announced the "Matter-compatible version of mui board 2nd generation" as the first Matter-compatible company in Japan.

Matter" is an industry standard for interconnecting smart home devices, and is expected to promote innovation and spread the smart home. By being the first to support "Matter," mui Lab will be able to use its multi-admin feature to provide a smart home experience that respects the personal time of individuals and families in a way that coexists with existing smart home platforms that offer convenience to people's lives. This new capability enables us to continue focusing on partnerships with more global companies.
