Creating a People-Friendly World Through IT

Not only seeking sales and profits or adopting the latest technology for self-satisfaction, but also not losing sight of "kindness to people."

Our company has been involved in the development of order screens for securities/FX using the latest technology, wallet development for cryptocurrency exchanges, large-scale multi-tenant e-commerce sites, and app development for major insurance companies, department stores, and musical instrument manufacturers, with many well-known companies as our clients. In addition, we provide on-site support for banks struggling with IT talent shortages, assist in system in-house development, and offer consulting on Web3, generative AI, and cloud services, covering a wide range of activities.

IT is evolving at an incredible pace, with new technologies emerging one after another. However, we must not forget that the foundation of IT development is the desire to "help someone" and "enrich people's lives." Our corporate philosophy, "Creating a People-Friendly World Through IT," embodies this belief, ensuring that employees and business partners can live in a kind world without exhaustion.

Those who share this philosophy and have joined us are committed to providing "ease" and "kindness" to people through IT. Not only do they possess high technical skills, but as a Japanese company, they also embody a proud spirit of service and hospitality, nurturing exceptional engineers who contribute to society. This is the very essence and most important mission of Stone System.

Message
Our company is not just a company that creates systems. With the desire to "help someone through IT," we nurture talented IT professionals and send them out into the world.
The founder (current chairman), after graduating from university, was responsible for aggregating sales data from stores nationwide. At that time, there were no convenient networks or systems like today, so he had to call each store individually to collect data, but he noticed a computer in the corner of the office and thought, "If I use this, I might be able to aggregate data more efficiently." He then started developing a data aggregation system on his own. The completed system was adopted for aggregation tasks.
This experience led the founder to realize the importance and fascination of systems in business, and at the age of 30, he became independent, overcoming challenges with the support of friends and the efforts of employees, and was able to grow the company to its current state.
