ExtenD Inc. (Head Office: Tosu City, Saga Prefecture, Representative Director: Mitsuru Kitaichi) is pleased to announce its selection for the 2025 "300 Companies of SMEs and Small Businesses That Shine," an initiative by the Ministry of Economy, Trade and Industry (METI) and the Small and Medium Enterprise Agency (SME Agency).

Our company was selected in recognition of our initiatives in the DX field, recommended by the Kyushu Bureau of Economy, Trade and Industry.

The "300 Companies of SMEs and Small Businesses That Shine" is a program that selects SMEs and small businesses that are expected to contribute to the growth of regional and Japanese economies by transforming their businesses and challenging new ventures in response to changes in the socio-economic structure.

As a startup originating from the National Institute of Advanced Industrial Science and Technology (AIST), we are working on the social implementation of "Liquid AI Sommelier®," which combines our proprietary diamond manufacturing technology using the hot filament CVD method with diamond electrode sensors and AI analysis technology.

Liquid AI Sommelier® is a technology that digitizes information obtained from liquids as "fingerprint information" through electrochemical measurements using diamond electrodes, and supports quality evaluation and difference discrimination through AI analysis. In areas that have traditionally relied on the experience of skilled individuals and sensory evaluation, such as wine and other alcoholic beverages, beverages, food products, and chemicals, we aim to contribute to the acceleration of evaluation processes, improvement of reproducibility, and digitalization of quality control.

Regarding this selection, the secretariat introduced our company's initiatives as follows:

"Fusing energy-saving diamond manufacturing technology with AI to digitize wine quality control. Breaking down manual processes with analysis in 1 minute per drop."

Furthermore, according to our internal research, three companies from Saga Prefecture were selected, and this is the second company from Tosu City to be selected in history.

Encouraged by this selection, we will continue to connect the potential of advanced materials like diamond to social implementation, contributing to the digitalization of liquid information in a wide range of industrial fields including quality control DX in the food and beverage sector, as well as environment, healthcare, semiconductors, and chemicals.
