About Cor.Inc.

Chasing "Kyousou."

Cor.Inc. is an AI implementation company based in Fukuoka. Our work centers on local LLMs that keep confidential data in-house, Grift — our own product that produces verifiable evidence — and contract development from design through operations, and we also help create opportunities for learning and community in the region. We listen closely to the real voices on the ground — "we want to do it, but it isn't moving forward" — and rather than treating AI as the goal, we offer technology as a means of solving real business problems.

What "Kyousou" means.

AI and systems create value only when they are used on the ground. That is why we are not simply order-takers who build whatever we are told. We face the challenge alongside our customers as equals, and when systematization is not the best path, we honestly suggest that it may be better not to build yet. We value the spirit of "Kyousou" — co-creating essential problem-solving together.

  • Co-creation

    Building together with customers, AI, and partners

  • Ensemble

    People, AI, and expertise each play a role and resonate

  • Competition

    Refusing yes-men and sharpening one another

  • Fantasy

    Not fearing ideas that have no shape yet

  • Fervor

    The energy generated in the market as a result

"Kyousou" is the implementation mindset that turns differences into outcomes.

Mission / Vision / Values

Mission

Through "Kyousou," unlock the potential of makers and their businesses.

Vision

Build a society where differences in values lead not to division, but to better implementation.

  • Co-creation without pandering

    We don't build relationships based only on going along with the other side. We ask candidly, push back when needed, and search for a better answer.

  • Speak through proof

    We don't stop at ideas alone. We show it through code, products, operations, and numbers.

  • Balance freedom and responsibility

    We don't bind people's abilities, and we protect the information that must be protected. We design comfort and trust at the same time.

  • Sharpen our differences together

    We turn differences in cognitive traits, expertise, and values into outcomes rather than compromise.

  • Unlock makers' true ability

    We use AI not as a tool to replace people, but as an extension that lets people bring out their true strength.

Founder's Story

Kousuke Terada

I Founded a Company to Make "Ah, They Understood" an Everyday Experience

Turns out, I was the alien

In kindergarten, I couldn't join in the group dances. When they sent me outside, I rode a tricycle around and around the yard.

At my elementary school entrance ceremony, I chased a butterfly that flew past me, right out of the gym.

Once, wanting to know whether a magnifying glass could really start a fire, I held one over a pile of fallen leaves for the whole lunch break. It started a small fire.

In my head, all of it made sense. I wanted to do something, and I went at it the fastest way I knew. But to everyone else, I must have been a kid who might do anything.

By fourth grade, no one invited me to play anymore.

So I devoured books on behavioral psychology at the library. Where people look, how they move, when they pause. Ways to read, from the outside, the feelings people don't put into words. By sixth grade, I was even trusted to be class president.

But I was always exhausted. Reading faces, choosing words that wouldn't spoil the mood. Talking that way, conversations ended without what I really thought ever getting across.

Wasn't there a more natural way for feelings to get through? I had been asking that since I was a child.
