Clarity comes first.
Every screen has a purpose. Every action has a response. We keep the essentials close and give them room to breathe.
Independent. From Romania.
We build Zumibo
and Hektro.
We are HidrogenONE, a Romanian technology company. Zumibo brings local places and services into one app. Hektro puts coding agents on one board, on the Mac.

Our own products.
Our full responsibility.

How we build
Quality is in
the way it feels.
At home on every platform.
Zumibo for iPhone, iPad, Android and the web. Hektro for the Mac. With care for the way people use each device.
Care beyond launch.
A product is not finished when it becomes available. We maintain it, improve it and take responsibility for it.
HidrogenONE
A good idea deserves
to feel second nature.
Two products, the same care: we build them, run them and stand behind them.
