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. is the company that founded and operates zumibo. 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.

How we build

Quality is in
the way it feels.

01

Clarity comes first.

Every screen has a purpose. Every action has a response. We keep the essentials close and give them room to breathe.

02

At home on every platform.

Experiences designed for iPhone, Android and the web. With care for the way people use each device.

03

Care beyond launch.

A product is not finished when it becomes available. We maintain it, improve it and take responsibility for it.

From idea to experience

The same care.
At every step.

  1. 01

    Understand.

    We start with a real need before proposing a screen or a feature.

  2. 02

    Design.

    We organise content and refine interactions until the next step is clear.

  3. 03

    Build and verify.

    We test behaviour and use the product in the situations it was designed for.

  4. 04

    Stay close.

    We operate the product, listen to questions and keep making it better.
