With DoneUnder
stress is over!

Since 2023, our platform has been the single source of truth for civil engineering infrastructure projects. Leading infrastructure companies already rely on our IT system. With the spin-off in 2026, we are taking the next step to give everyone involved the opportunity to make informed decisions in construction with our platform.

A shared ambition: not to manage complexity, but to reduce it.

We combine technical depth with the will to move things forward. We implement small things with seriousness, big things with the necessary ease.
We develop and move quickly!

Friendly, fair, and transparent. This is exactly how the solution is intended: systems that provide support and create clarity.

One principle remains central:
Good IT does not replace communication. It makes it better.

Too many systems

Our answer

The next step

Those who, like us, come from IT and construction know the challenges that shape everyday project life: a lack of overview, insufficient control, and a lot of manual work. From the client to the subcontractor, everyone works with different data versions. Problems too often only become visible when they are already incurring costs.
We have experienced this reality ourselves and decided to change it. With a platform that starts exactly where projects fail today: the lack of a shared project status.
Our focus is clear: a central foundation that everyone can rely on. Progress becomes visible, decisions become reliable.
Since 2023, our technology has already been in use by leading companies in Europe for fiber optic expansion.
After several million meters of route construction and several 100,000 documented locations, we are taking the next step in 2026: as the first all-in-one platform for civil engineering and beyond. Ensuring that projects are transparent, reliable, and predictable—for everyone involved.
