Making construction sites desirable places to work.

All industries have been made more convenient by ICT (information and communications technology).
However, only the construction industry
remains unchanged.

Although many before us have challenged the old ways,
new values and ways of thinking have never been created.

Here, Sukedachi takes up the challenge.
Based on history, this might seem reckless.
People with common sense say it’s impossible.
For us, that is what makes the challenge worthwhile.
With our deep knowledge of the construction industry and our app development skills,we can do it.

We will dig deep into the roots of the industry and redefine it.
We will be a fundamental game changer.
It is our mission.
