Sustainability
~Contributing to Social Issues through the Power of IT~

This has been our unwavering attitude toward our work since our founding.

In 2013, with this conviction in mind, our founder, Michiyo Sasaki, started as a sole proprietor in Shibuya with just one million yen.
In 2017, we relocated to Yokohama and incorporated the company. Later that same year, we moved our base to Numazu City in Shizuoka Prefecture, my hometown, where we continue to operate today.

Throughout our journey, we have received tremendous support and valuable lessons from our customers and partner companies.
Though our goals are ambitious, we remain uncompromising, steadily advancing our technologies each day. With Japan and the world as our stage, we will continue striving to contribute to solving social issues through our work.

Message from the CEO


The thoughts behind "greemin-bigwell"


I first encountered programming during my university years, and was fascinated by the joy of creating something from nothing and the endless possibilities it held.
Even today, as this industry continues to evolve at a rapid pace, pursuing the limitless potential of IT is deeply meaningful to me. I am committed to ongoing research and development without pause.

Among all of this, what we value most in our work is the belief that strong, trusting relationships between people are the foundation of great work.
By carefully considering what should change and what must be preserved, we aim to be a company that offers warm, human-centered services—even in the seemingly impersonal world of IT.

With sincerity, a passion for learning, and deep gratitude, we will continue moving forward.
We sincerely hope that you will make use of our technologies over the long term and walk this journey with us.
