“They responded right away, even when customer feedback changed our direction” — Two years through a pivot, supporting the launch of an enterprise SaaS

SkillAX is an enterprise SaaS that defines the AI and DX skills a company needs, assesses each employee's level, and supports their growth. micata worked on its predecessor, Hana-chan, for about 14 months, and on SkillAX for about 13 months after the pivot, supporting everything from specification to design, infrastructure, and development. With full rollouts and trials now under way at major manufacturers and financial institutions, we spoke with product manager Takashi Aihara and engineer Tetsuya Yanagishita about what went on behind the launch.

Challenge
Building on what they had learned from a consumer service, the team redefined the business for enterprises, where demand was strong. The direction — "start with skill assessment" — was set, but the actual features were not. They needed to build, from scratch, a system that measures skills accurately and returns results people find convincing.
Support
APOLLO's engineering team built the AI core, including the skill definitions and the question engine. micata focused on turning the AI features into an application, covering everything from organizing the specification to UI design, infrastructure, backend, and frontend as a single team. To validate the business, we delivered quickly and kept improving the product based on customer feedback.
Result
Full rollouts and trials are under way at major manufacturers and financial institutions (as of October 2026). Customers value the quality of the assessments and the ability to customize skills for each company in particular.

INTERVIEWEE

Takashi Aihara

Takashi Aihara

Product Manager, SkillAX. Manages the development team and also handles customer success, including onboarding support.

Tetsuya Yanagishita

Tetsuya Yanagishita

Engineer, SkillAX. Started in quality assurance for the assessment questions and now works on product development.

We care most about measuring skills accurately

To start, could you tell us what SkillAX is?

Takashi Aihara

Aihara

SkillAX is a product for enterprises that supports digital talent end to end — defining skills, assessing them, and helping people grow. More and more companies are starting to certify and develop AI talent internally, and that is what we support.

What sets it apart is that it assesses skills accurately. Who to give which work to, and where to invest in development — those decisions start with an accurate picture of people's current skills. That is why we care most about measuring accurately. We also define skills in much finer detail than other products, so it can be customized for each company. Going forward, we want to expand the features that support individual growth as well.

Tetsuya Yanagishita

Yanagishita

That is why the assessment is where we put the most effort in development. With AI, it looks easy to generate questions. But whether those questions really measure ability accurately, and whether people find the results convincing, is much harder. Unless we can guarantee that, users won't keep using the product.

What are your roles?

Takashi Aihara

Aihara

I am the PM for the whole product. Besides managing the development members, I now also work in customer success, so I deal directly with customers, including onboarding support.

Tetsuya Yanagishita

Yanagishita

I work on development as an engineer. In SkillAX, we don't leave question writing entirely to AI — there is a step where people check the quality. I started out in that quality assurance step, and my scope in development has gradually grown from there.

They took over the work right at the time of the pivot

What led to the launch of SkillAX, and how did you come to consult micata?

Takashi Aihara

Aihara

There was a discussion inside the company about launching a new product around talent development. AI had become usable in all sorts of situations, and developing AI and DX talent had become a major trend. On top of that, ever since Hana-chan (our earlier consumer product), we had felt the need for a product that "widens people's possibilities." That was the background.

The biggest reason we asked micata was the relationship we had built on Hana-chan. We redefined the business for enterprises, where demand was strong, building on what we had learned from consumers with Hana-chan — and they took over the work as it was at that moment. I already saw them as a company that was strong at launching businesses quickly, so I felt comfortable leaving it to them.

When you first consulted us, how much had been decided?

Takashi Aihara

Aihara

I think the direction — "let's start with skill assessment" — had been decided. But the actual features had not been clearly defined. We built them up from there, aligning on the vision and direction as we went.

Even when customer feedback changed our direction, they responded right away

We worked together from the specification through to design. Honestly, what was your impression once things got going?

Takashi Aihara

Aihara

Above all, they moved fast. When we asked for a change of direction based on customer feedback, they responded immediately, and I was really grateful for that.

Tetsuya Yanagishita

Yanagishita

I think micata's strength was that they could do everything — design, infrastructure, and backend. APOLLO handled the AI core, and micata handled the application that delivers it as good features and a good experience. That division of roles let us combine each other's strengths, and it worked really well.

How did you balance speed and quality?

Takashi Aihara

Aihara

From the launch phase, we designed the testing approach and quality standards together and kept improving while verifying. Having them think it through with us made a big difference in raising quality without slowing down.

Being able to "measure people properly" was what decided the full rollouts

What is the current status of rollouts and trials?

Takashi Aihara

Aihara

Full rollouts and trials are under way at major manufacturers and financial institutions.

How have customers responded?

Takashi Aihara

Aihara

What customers value most is that, compared with other products, the assessments are high quality and evaluate people accurately, and that the product can be customized to their own company's skills.

We are also developing an AI agent right now, and we show the features in development to companies as we go. Some have told us there is no other software like this. I think they appreciate how we dive quickly into new things and keep building features.

We are also continuously expanding the admin features based on customer feedback.

What do you think made trials turn into full rollouts?

Tetsuya Yanagishita

Yanagishita

I think it comes down to the quality of the assessments. Companies want to develop AI and DX talent, and SkillAX's ability to "measure people properly" matched that need well.

Takashi Aihara

Aihara

The companies that have adopted it — both the organizations and the participants — are approaching it with a lot of energy. Working with companies like that is enjoyable for us, and we are grateful for it.

micata suits companies that want to build good things fast

What are your plans going forward?

Takashi Aihara

Aihara

We want to grow the product around its strength of judging and diagnosing skills accurately. Right now we work on two fronts — skill assessment and building knowledge through learning — but we are also looking at assessing soft skills, assessments in the form of conversations with an avatar, and making use of data from talent management systems. We also plan to expand beyond the current AI and DX skill areas.

What about your development setup going forward?

Takashi Aihara

Aihara

We plan to put together the best development setup as we expand the features. When it is time to build new features, we may well reach out to micata again.

Finally, what kind of company would you recommend micata to?

Tetsuya Yanagishita

Yanagishita

These days, with AI, you can build things quickly even without much engineering experience. Even so, developing quickly while ensuring quality is still hard to pull off. micata develops quickly while making proposals across infrastructure, backend, and design, so for companies that want to build a good app fast, I think a company like micata is the best fit.

Takashi Aihara

Aihara

Companies that want to launch something new, and launch it fast. I think the biggest point is that they can develop quickly by reusing libraries and know-how built up on other projects.

We have worked together for about two years, through the pivot from Hana-chan to SkillAX. We have always been able to raise whatever we noticed with each other, and I feel we have run as a good team. The real journey for SkillAX starts now, and we will keep cheering it on.
