Valtes Solutions & AI Inc. launches

Valtes Holdings Inc. (Headquarters: Osaka City, Nishi Ward; Tokyo, Chiyoda Ward; Representative Director, Chairman and President: Masashi Tanaka, hereinafter "Valtes Holdings") and Valtes Solutions & AI Inc. (Headquarters: Tokyo, Chiyoda Ward; Representative Director and 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 by the absorption and merger of Mint Inc. into Sinfour Inc., which will be the surviving company, 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. The "AI" signifies our aspiration to be a company that continuously creates new value by actively promoting the provision of advanced solutions and the sophistication of development processes, not limited to traditional system development, but also by actively utilizing AI technology.

Logo Concept

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

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

On July 1, 2026, we launched "Valtes Solutions & AI Inc. (VSOL)" by integrating R.S.R. Inc., Sinfour Inc., and Mint Inc., companies that had previously operated independently.

What we value is the simple and unwavering principle of contributing to our customers' profits through technology. Until now, the three companies each possessed different strengths in development, testing, and maintenance, and operated individually. 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 before others, we can create value while the rest of the world catches 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 work with 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 safe and secure ICT society, starting with software quality.
