(Komae, Tokyo; Representative Director Kota Miyamoto) is preparing n1a, a service that matches executives with compatible personalities by combining Big Five assessments, meeting conversation data and company attributes.

Summary
ZETTAICHI Inc. is a company in Komae, Tokyo, founded in July 2026 and led by Kota Miyamoto. Under the motto “Absolute value for the world,” it runs sales support that creates meetings with decision-makers, n1a, an executive matching service based on personality, and executive networking events. n1a was still in development as of October 2026.
- n1a combines a Big Five assessment (IPIP-50, 50 questions), meeting conversation data and company attributes to match executives (in development as of October 2026)
- Sales support starts with interviewing the client and goes as far as joining meetings with decision-makers, prioritizing quality over volume
- The name comes from “absolute value” in math: failure and regret also count as experience
Meeting as people, not just as companies
Plenty of events and cold calls, yet few meetings that move the business. n1a, the service Kota Miyamoto of ZETTAICHI is preparing, is aimed at executives in exactly that position.
It combines a Big Five assessment (IPIP-50, 50 questions), what people say in online meetings and company attributes to connect executives with compatible personalities. When a good match appears, scheduling and calendar entries happen automatically. As of October 2026 the service is still in development, though the assessment can be taken in advance.
| If you are facing | What they can do |
|---|---|
| Events and cold calls rarely lead to meaningful meetings | Choose partners by personal fit, not just industry and size (n1a, in development) |
| You never get past the gatekeeper to decision-makers | Sales support that starts with your story and sets up, and joins, meetings with decision-makers |
| You cannot put your strengths or meeting habits into words | A 50-question assessment and AI describe your strengths and meeting style (n1a, in development) |
Three “planets”
The company describes its businesses as planets: PLANET A is sales support that creates meetings with decision-makers, PLANET B is n1a, and PLANET C is executive events. All three are about people meeting people.
Its events include Biz Summit! and ASOBMENT, a community Miyamoto co-founded, where executives play games like Werewolf and get to know each other beyond their titles.

Quality over quantity
In a January 2026 interview, when he was COO of AddBox, Miyamoto said sales outsourcing tends to chase the number of meetings, while his team values quality. They use every service themselves first, so meetings start from concrete use cases rather than needs discovery.
