CEO message

I am an outsider in R&D market.

Why did I decide to start a business in this field?
It was because I felt a strong sense of discomfort with the current situation of scientists from the standpoint of a third party who is not a member of the R&D field.

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.
Also, unlike the IT industry today, corporate researchers, although highly skilled and knowledgeable, were limited access to the platform to provide their R&D related skills during a free moment.

"Why is it that these people, who are so logical and talented, are not provided with an environment that matches their abilities?"

In the financial industry, where I worked as M&A advisor and doing investment works by creating a fund, was a relatively favorable "market", both in terms of the economic environment and the diversity of providing their skills.
This was not because of the superiority of the human resources, but simply because of the market environment that had been created.

We can not ignore the current market situation since science have a deep relationship with our life. It can improve our life style by causing 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 building an environment where people can continue working as scientists as a matter of course.
