Clarity comes first.
Every screen has a purpose. Every action has a response. We keep the essentials close and give them room to breathe.
The company
A clear vision.
For the long run.
HidrogenONE is an independent Romanian technology company. We create our own products and care for them, from the first idea to everyday use.
HIDROGENONE S.R.L.
From Romania.
For the real world.
HIDROGENONE S.R.L. builds and operates Zumibo and is preparing to launch Hektro. Our registered office is in Bacău county. Bucharest is the first city where we are building the Zumibo experience.
We start with tangible needs: time lost making a booking, an available slot that is hard to find, a local business worth discovering. We build technology around those needs.

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.
