VISUAL CONCEPT / AI GENERATED

01 / THE NEXT FIELD

Bring the strengths you built in sport to work that helps people with AI.

There is more room
to find what moves you.

What work comes after sport? Where can the experience you have built make a difference?

A3T Shiki is a joint initiative by Athlete Shiki, which supports athletes' careers, and A3T, the AI implementation company spun out of PROTHENTIA.

We connect the capabilities developed in sport with work using AI. Listen to clients' difficulties, then turn daily manual tasks into systems that can be delegated to AI.

ATHLETE CAREER

Athlete Shiki

Supporting athletes' careers.
Bring the experience built through sport to your next role.

AI & TECHNOLOGY

A3T

Building systems with AI.
Find a new way to handle the tasks repeated every day.

02 / WHAT YOU ALREADY HAVE

What you have built
can serve you in your next role.

01

Try. Adjust.
Try again.

What change would produce a different result? The experience of thinking and testing for yourself becomes the ability to build a system, run it, and improve it.

02

Take feedback.
Get better.

A coach's or teammate's words become the next play. At work, too, another person's perspective helps you build something better.

03

Keep going,
even when results take time.

The habits formed through training become the ability to investigate what you do not understand, one question at a time, and stay with it until you find a way through.

Every sport, position, and person is different. So is the work that suits them.
We will discover together where your strengths make a difference.

03 / ONE ATHLETE’S STORY

Bring the strengths built in sport to a new field. Photographs have been artistically processed using AI.

Today grows
out of a life
in sport.

Ochi / Former footballer

JEF United Ichihara Chiba U-15/U-18 and the Meiji University football team. After graduation, he played for four years in the United States, Japan, and Australia.

Concerned about work and income after retirement, he entered AI-related work without prior experience. Within three months, he was responsible for some features of a system central to the company.

Today, he listens to clients' challenges, decides what to build, and makes it real. Alongside a sense that the resilience and habits formed in sport are useful, his options in work, relationships, and personal life are expanding.

04 / THE WORK, UP CLOSE

A conversation with AI
becomes something that works.

Reduce time-consuming tasks. Make the information people need easier to find.

Ochi builds systems that support clients' daily work. From understanding what is difficult to building and improving a solution, he moves forward through dialogue with AI and colleagues.

  1. 01 / UNDERSTAND

    Understand the challenge,
    together.

    Listen to the client and organize what you learn with AI. Where does the effort go? What change would help? Through dialogue, identify what to work on.

  2. 02 / BUILD WITH AI

    Turn an idea
    into something that works.

    This could be easier to use. Discuss that idea with AI and turn it into a screen or a system. Once it runs, you can see what to try next.

  3. 03 / CHECK & IMPROVE

    Improve it
    with the people who use it.

    Let clients try it and listen to their reactions and observations. Keep improving with AI and colleagues until it becomes useful in everyday work.

05 / LEARN BY BUILDING

First, build together.
Then, own the challenge.

What should you build, and how should it work to be useful? Think it through with AI, create code and screens, and check the actual behavior together.

No programming experience is required. Work alongside someone who joined before you, have them review your work, and learn by making corrections.

  1. Indicative: joining to 3 months

    Build together

    Build your part with review and guidance from an experienced colleague.

  2. Indicative: 3–6 months

    Build independently

    Take responsibility for a feature, investigate what you need, build it, and improve it.

  3. Indicative: 6–12 months

    Own the challenge

    Talk with clients and help determine what to build.

06 / VALUE & REWARD

Broaden your responsibility.
Increase the value you bring.

As your capabilities and responsibilities grow, fixed pay rises. Results contribute to incentive pay. The model is designed to let you aim for the next role without relying on tenure alone.

07 / YOUR POSSIBILITIES

There is more than one path.

Where will you take the capabilities you build?
As you develop, more choices become possible.

Design and deliver demanding projects as a senior engineer or tech lead.

02

Help others learn

Support athletes entering the field as a trainer or mentor, teaching through real work.

03

Share your experience

Tell your story in interviews and events as a communications representative or ambassador.

04

Take your skills elsewhere

Move into an in-house AI role, independent work, or another setting where your skills can make a difference.
