Karhu LabAX Design Studio

Designing how we work,
in the age of AI.

Across people, organisations, work and technology,
we design environments where people and AI work well together.

A gentle margin
between technology
and people.

Why hasn’t the way we work changed,
even after we adopted AI?

Tools nobody uses. AI used by a few.
More rules, and the same old work.

Maybe the problem isn’t the AI’s performance.

Work, people, organisation.
Add technology without changing how they relate,
and the change won’t last.

Karhu Lab doesn’t stop at adopting AI.
We also ask how work itself should change.

Toward a way of working where people and AI fit together.

Question
before solution.

WHERE TO START

Wanting to change
is enough to start.

The concern closest to yours
is where to start.

AX DESIGN / 02 — WHAT IT IS

AX = AI Transformation. Starting from AI, changing the way we work itself.

AX DESIGN

  1. 01 — Technology

    AI, by itself,
    changes nothing.

  2. 02 — Learning

    It starts moving only when
    people learn and begin to use it.

  3. 03 — Workflow

    Built into the flow of work,
    it becomes a colleague you can trust with tasks.

  4. 04 — Transformation

    Team relationships and organisational systems change,
    and it takes root.

  5. AX Design

    Starting from AI, we reconnect how people learn, how work flows, how teams relate and how the organisation runs, and turn it into change that can actually be practised, where people and AI agents work together. That is what Karhu Lab means by AX Design.

SERVICES / 03

From concept to build,
to lasting change.

Ask for just one of these, or all of them together.

How we work

  1. 01THINKFind the real problem

    From the floor’s “this is a pain” and “something’s off”, we narrow down the real problem.

  2. 02DESIGNDesign the change

    We redraw how work flows and who does what, in a shape people can live with.

  3. 03LEARNGrow the people

    Not just listening, but starting to use it in your own work.

  4. 04MAKEActually build it

    We build small, and fix it while it’s used on the floor.

  5. 05TRANSFORMMake it take root

    Not the effort of a few, but a shape the team can keep going.

SELECTED WORK / 04

Thought it through, built it,
kept it going.

01

Generative AI adoption that sticks

Not stopping at rollout: training and workplace experiments until AI is built into daily work and stays in use.

Corporate

02

AI talks and training for executives,
managers and teams

Layered talks and hands-on training that bring it down to “how do I use this in my job”.

Organisation

03

Designing and running in-house academies
and DX talent programmes

Learning designed as a system that keeps running inside the company, not a one-off event, and running it too.

Learning / Org development

05

Planning and building workflow apps
and AI prototypes

Tools that start from what’s tedious on the floor, built small, tried, and grown in use.

Operations / Prototyping

FAQ / 05

Frequently asked questions.

I don’t know much about AI. Can I still talk to you?

Yes. Starting from “not knowing much” is exactly Karhu Lab’s job. A vague sense that something’s off is enough.

What should I bring to a first conversation?

Either “what’s bothering us now” or “a hunch that AI could help”. In the free first conversation we sort out the situation and find what’s needed, together.

We’re a small company. Is that OK?

Yes. We work with companies from small to large: owners, DX leads, HR and team leaders. What matters isn’t size but whether you want to change.

Do you work outside Fukuoka?

Yes, across Japan — talks, training and ongoing support, in person or online.

What does it cost?

From one-off talks and training to ongoing support and advisory retainers, we shape it around your budget. The free first conversation is where we sketch what’s needed.

CONTACT / 06
