Valtes Solutions & AI Inc. Launches

Valtes Holdings Inc. (Head Office: Nishi-ku, Osaka; Chiyoda-ku, Tokyo; Representative Director, Chairman and President: Masashi Tanaka, hereinafter Valtes Holdings) and Valtes Solutions & AI Inc. (Head Office: Chiyoda-ku, Tokyo; Representative Director, President: Yuichi Nishimura, hereinafter Valtes Solutions & AI) are pleased to announce that Valtes Solutions & AI has launched as a new system to provide integrated support for development, quality assurance, operations, and maintenance, effective July 1, 2026.

Valtes Solutions & AI Inc. was established based on the group organizational restructuring announced by Valtes Holdings on April 23, 2026. It was formed through the absorption and merger of Mint Inc. by Sinfour Inc., which will continue to exist, and the succession of the contract development business, etc., of R.S.R. Inc., followed by a change of trade name.

By consolidating the expertise cultivated by the three companies, we will build a system that provides integrated support from system development to quality assurance, operations, and maintenance. We will also strive to create new value by actively utilizing AI, thereby supporting our customers' business growth.

Origin of the Company Name

The name "Solutions" reflects our desire to be a company that provides optimal solutions for our customers' challenges. "AI" signifies our aspiration to be a company that continuously creates new value by actively utilizing AI technology to provide advanced solutions and enhance development processes, going beyond traditional system development.

Logo Concept

The logo visually represents elements of different colors coming together to form a "V." This design symbolizes "comprehensive strength," where diverse specialized fields and expertise combine to create robust solutions and unwavering trust.

Greeting from Yuichi Nishimura, Representative Director, President of Valtes Solutions & AI Inc.

On July 1, 2026, we launched Valtes Solutions & AI Inc. (VSOL) by integrating R.S.R., Sinfour, and Mint, three companies that have operated independently until now.

What we value is the simple and unwavering principle of contributing to our customers' profits through technology. Until now, the three companies have had distinct strengths in development, testing, and maintenance, and have operated separately. By bringing these together under one company, we have established a system that can provide integrated support from development to quality, operations, and maintenance.

AI is at the core of this endeavor. AI is a technology that everyone will eventually use, but it will be difficult to differentiate ourselves once it becomes commonplace. By tackling it ahead of others, we can create value before others catch up. That is why we will continue to challenge new frontiers.

Valtes Solutions & AI aims to be a valuable group that customers say, "We definitely want to ask them." We believe that being continuously chosen by our customers will lead to growth opportunities and job satisfaction for each of our employees.

Valtes Solutions & AI will support our customers' business growth towards the realization of a secure and safe ICT society, starting with software quality.
