We accelerate the research activities of companies and research institutions by maximizing the value and potential of the researchers.

CEO message

I am an outsider in the R&D market.

Why did I decide to start a business in this field?
It was because, as an outsider to the R&D field, I felt a strong sense of discomfort with the current situation of scientists.

Although I originally majored in biomedical sciences, I became interested in business after I participated in the planning of a new business and the establishment of a company in my second year of undergraduate school.
When I was assigned to a laboratory in my fourth year, my supervisor allowed me to participate in an internship during the daytime and conduct research works from evening to late at night.
Between that time period, I heard the actual employment situation in the R&D industry from many post-doctoral fellows, and I still remember how shocked I was to learn that some PhDs who had obtained their Ph.D. degree before the age of 30 were earning less than 300,000 yen per month.(*approximately USD 2,000 per month)
Also, unlike the rapidly evolving IT industry, highly skilled and knowledgeable corporate researchers often face limited opportunities to apply their research skills.

"Why aren't suitable environments provided for such logical and talented individuals whose capabilities are so exceptional?"

In the financial industry, where I worked as M&A Advisor and doing investment work by creating a fund, it was a relatively favorable "market," both in terms of the economic environment and the diversity of opportunities to use skills.
This was not because of the superiority or inferiority of the people working in this field, but simply because of the market environment that had been created.

We can not ignore the current market situation since science has a deep relationship with our life. Science can improve our lifestyle with innovation.
That is why I decided to start the business with the hope of building such a "market" in the R&D field, and to help scientists who are competing against the world.

Again, I am an outsider in this industry.
So I am truly aware of the need for support from various people.
As a person who believes in the potential of scientists more than scientists, I will operate our business with the aim of creating an environment where people can continue working as scientists as a matter of course.
