Business

Three things. That's all.
01

Investment & R&D

Investing on our own judgment, and research and development using AI. We keep only what survives verification. This is the core of turning tilt into structure.

02

Advisor to Founders

Sitting alongside business owners as they make decisions. Where and how to put AI into a business gets decided here too. Not handing over answers — standing on the same side and finding the structure together.

03

Publishing & Media

Over 200 books published. Through books and social media, we record ways of thinking and the tools that go with them, and deliver them to the people who need them.

CHIERO — Kou Nakata

FOUNDER & CEO

Born in Fukuoka, Japan. Studied IT and medicine at Kyushu University Graduate School, then left the research path to become a professional street performer — on the streets of Fukuoka and Tokyo, and as far as Sydney, Australia. Juggling and magic, stopping a hundred people in the first thirty minutes.

After about two years at an IT company in Tokyo working on marketing and problem-solving, he returned to Fukuoka and founded CHIERO Inc. in December 2020. Today he works on investment and R&D funded by his own capital, advises business owners, builds products, and writes.

History

This is a one-person company, so the company's history and the founder's are not kept apart. They are the same line.

  1. 2013Studied IT and medicine at Kyushu University Graduate School (Systems Life Sciences). While still enrolled, left the research path to become a professional street performer. From the streets of Fukuoka and Tokyo to Sydney, Australia. Juggling and magic — a hundred people stopped in the first thirty minutes. His stage name, Chikkoi Piero (“the little clown”), later became CHIERO.
    The handwritten sign: My name is CHIERO / Juggling!
    The handwritten sign he set on the pavement back then. The company name comes from here.
  2. 2018Joined an IT company in Tokyo. Two years on the ground in marketing and problem-solving. The instinct for the moment a person stops walking, learned on the street, gained logic and numbers here. Both halves of the current work came together.
  3. 2020Returned to Fukuoka. Founded CHIERO Inc. in December. No employees — started alone.
  4. 2022Launched a video advertising business. Repetitive work goes to AI; people face only the decisions — the shape still in use today was settled here.
  5. 2023Interviewed in April by the business media Shin-R25 for its “The Next Creators” feature. In July, appeared as the first guest on the YouTube programme “The Philosophy of a Founder.”
  6. 2024Began publishing on Kindle. From philosophy and Eastern thought to practical books on AI. If you cannot write it, you do not yet understand it — that is why he keeps writing.
  7. NowInvestment and R&D at the core, alongside advising founders, building products, and writing. Over 200 books published. Provided footage to Nippon TV's The Tetsuwan DASH. Alumnus of the World Economic Forum's Global Shapers Community, and a councillor of the Ishibashi Scholarship Foundation, a public interest foundation in Fukuoka.
