# “Even B2B comes down to people.” ZETTAICHI’s Kota Miyamoto is building n1a, which matches executives by personality and conversation - Company: ZETTAICHI Inc. - Industry: Consulting - Area: Tokyo (All of Japan) - Representative: Kota Miyamoto (Representative Director, ZETTAICHI Inc.) - Website: https://zettaichi.co.jp/ - Published: 2026-11-08 / Updated: 2026-11-08 - URL: https://businesslife.music-japan.com/en/companies/zettaichi/ ## What does ZETTAICHI do? 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. ZETTAICHI Inc. (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. It was in development as of October 2026. The company also runs sales support and executive events. ## Key points - 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. ## 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. ## Problems they solve | 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) | ## Services - **Sales support (PLANET A)**: From interviewing the client to setting up and joining meetings with decision-makers (https://zettaichi.co.jp/) - **Executive matching n1a (PLANET B)**: Matches executives using Big Five results, meeting conversation data and company attributes, with automatic scheduling. In development as of October 2026 (https://n1a-cxo.com/) - **Executive events (PLANET C)**: Biz Summit! and ASOBMENT, a community where executives get to know each other through games ## What sets them apart 1. **Quality over quantity**: They try every service they sell themselves first, so meetings can start from concrete use cases rather than needs discovery. 2. **Personality as data**: n1a is being built to read personal fit from a public psychology scale (IPIP-50) combined with what people say in meetings. 3. **From play to business**: ASOBMENT held its sixth event on September 25, 2026, turning “getting to know people beyond business cards” into a business. ## The founder: Kota Miyamoto After graduating from Aoyama Gakuin University, he spent about four years in sales and marketing at an advertising agency, then worked freelance on sales support and new businesses, where he saw the potential in systems that connect companies, people and services. In 2024 he co-founded AddBox with a high school classmate and served as COO, then founded ZETTAICHI on July 7, 2026. His starting point is “assume success”: think about how to make it happen before listing reasons it cannot. > Assume success (His guiding principle (from public information on Baton Partners)) ## A good fit for - Executives who tried events and sales outsourcing without meaningful meetings - Companies that want to work with people they truly trust - B2B companies that want more meetings with decision-makers ## Company profile - Company: ZETTAICHI Inc. - Representative: Kota Miyamoto - Founded: July 7, 2026 - Capital: JPY 1 million - Address: 1F, 2-32-25 Motoizumi, Komae, Tokyo - Business: Sales support, executive matching platform, executive networking events - Corporate site: zettaichi.co.jp (https://zettaichi.co.jp/) - n1a: n1a-cxo.com (https://n1a-cxo.com/) ## FAQ ### Is n1a available now?
