Keio Innovation Initiative (Headquarters: Minato-ku, Tokyo; Representative Director & President: Kotaro Yamagishi; hereinafter "KII") has invested in Graphenory Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director & President: Reii Hirano; hereinafter "Graphenory"), a startup originating from Keio University, through a third-party allocation of new shares from a fund it operates. Including funding from other investors, Graphenory's total raised amount in this seed round through third-party allocation of new shares is approximately 240 million JPY.

### Revolutionizing the Semiconductor Industry with Innovative Optical Devices Utilizing New Material Graphene

Graphenory is a startup established in October 2024, based on the research achievements of Professor Hideyuki Maki of the Faculty of Science and Technology, Keio University. By integrating the new material "graphene" with optical device technology, Graphenory has successfully commercialized the world's first graphene light source and optical devices that operate on semiconductors, which was previously difficult.

This innovative technology is expected to be commercialized not only in the sensing domain, such as realizing infrared analyzers with high spatial resolution exceeding theoretical limits, but also holds great potential to bring about societal transformation across various industries including bio, medical, information communication, and the next-generation optoelectronic convergence fields.

Through this funding, Graphenory will further accelerate talent acquisition, technology development, and business development, promoting the social implementation and application development of graphene optical devices.
