Kenichi Uchiumi
内海 賢一
Founder, mare interno LLC
Since 1995 I have stood between systems and the people who use them. Store registers, data exchanged between companies, web measurement, and now access by AI. The things I connect have changed; the work has not.
When the numbers don’t match or the systems don’t fit together, I step in between and connect them again.
The ring of experience
The three islands with bridges are my businesses today. The two without bridges are experience I carry with me.

Connect with the web
I rebuild web measurement infrastructure with GA4 and server-side GTM.
Connect with AI
I observe the AI that comes to read websites, and read the people behind it.
Connect with people
I work on the sales floor, connecting the people who sell with the people who buy.
Store registers (POS)
For a drugstore chain of about 1,000 stores, I handled some 3,000 registers from installation and replacement to maintenance and hardware procurement. For months I visited three stores a day, swapping registers after closing time.
Business-to-business (EDI)
Absorbing each trading partner’s data habits and carrying them onto a shared system: a translator between companies. I once went supplier by supplier for a department store to connect them.
