THE KINGFISHER / A NEW PERSPECTIVE

g9n LLC · Designing social infrastructure for the AI age

AI ProductAI TransformationSocial Infrastructure

01What we do

From concept to systems that run in society.

We never treat AI as the goal. We start from the business and the people on the ground, design where humans meet technology, and build systems that keep being used.

01 / PRODUCT

AI Product

Planning and building AI products

From finding the problem to service design, prototyping and development — we ship products that support human judgement and creativity.

Service designPrototypingProduct development
02 / TRANSFORMATION

AI Transformation

Business and operations designed around AI

We revisit daily operations and decision-making, design how AI fits in, and plan all the way through to running it after launch.

03 / INFRASTRUCTURE

Social Infrastructure

Systems that connect people and society

Crossing the boundaries between companies and fields to connect people, information and services — the touchpoints society needs in the AI age.

INITIATIVE / 01

Social implementation

AI × SME Transformation

Give small teams enterprise-grade intellectual productivity — and leapfrog.

We redesign operations on the premise that AI agents are always on the team, so small and mid-sized companies can leap past the scale barrier with enterprise-grade productivity and decision speed.

Contact us for details of specific engagements and results. Contact us →

Bringing agent-resident operations design to SMEs so they gain the productivity and decision speed to break through the scale barrier.

INITIATIVE / 02

Social implementation

AI × Art

Not generating art — rebuilding how art relates to society, with AI.

Rather than an art-generation tool, we use AI to visualise art's social and economic impact, design secondary-market mechanisms that pay artists back, organise the context unique to Japanese art, and support art-led solutions to social issues.

Contact us for details of specific engagements and results. Contact us →

Using AI to visualise art's social and economic impact and to return secondary-market value to artists.

INITIATIVE / 03

Social implementation

AI × Community Currency

Redesigning regional economies to be participatory.

We treat community currency not as mere e-money but as a means to support social welfare, circulate value within a region, and rethink how people live once AI takes over work — together with local governments.

Contact us for details of specific engagements and results. Contact us →

Working with local governments on community currencies as a means of regional circulation and social welfare.

INITIATIVE / 04

Social implementation

AI × Wedding

Weddings, from peer pressure to genuine excitement.

As more couples see weddings as a waste of time and money, we use AI to redefine marriage and weddings in a way the Gen Z couples now taking centre stage actually want.

Contact us for details of specific engagements and results. Contact us →

Redefining marriage and weddings with AI for a Gen Z generation that now takes centre stage.

INITIATIVE / 05

Social implementation

AI × ERP

Business systems, redesigned for agents.

Instead of people operating a traditional ERP, we rebuild workflows and permissions on the premise that agents do.

Contact us for details of specific engagements and results. Contact us →

Rebuilding ERP workflows and permissions on the premise that agents, not people, operate them.

04Our philosophy

People can live far more creatively.

The further AI advances, the more we ask:
what should human time be spent on?

Freed from complex procedures and repetitive work, people can turn to thinking, making, and facing one another. Connecting the potential of technology to the potential of people — that is where every g9n design begins.

Technology should give time back to humans.
