Who we are

HQ : Minato-ku, Tokyo
Established : 2013
Employees : 726 (as of the end of January 2022)

GA technologies is a fast-growing company in the X-tech, the next-generation industrial revolution.
In the first five years after founding our company, we have listed our shares on the Mothers market (one of Tokyo Stock Exchange’s markets for the startup companies), and in about eight years, we have reached 85 billion JPY in sales. We are about to become a company that represents the future of Japan.

We are evolving in the real estate market, a huge legacy industry that has existed for 70-80 years.
Nowadays, more and more legacy industries are being reformed by AI and technology.
Finance, insurance, healthcare, agriculture, education, and construction. Of course, real estate is one of them.

However, the real estate industry has yet to see a clear market leader who revolutionize the industry with technology.
With our founding aspiration of “creating a world-leading company that inspires people through technology × innovation,” we are determined to change this huge market through the power of technology.

If you want to work for a company that will create a new industry, rather than a company that has succeeded in its current industry, why not join us and work together to create us the world’s top company?
