How we work
Design
Concept and clickable prototype - you see your product before it gets built.
Build
Development in short sprints. Visible progress every week, no black-box development.
Deliver
Launch, measurement, iteration. We stay on board until the numbers are right.
No black-box development: every sprint you see what is being built - and understand why.
What clients say
I“entsorgo is a fast-growing start-up in the waste-management industry. In DUNA we found a highly reliable partner who built, evolves and continuously supports our complete ERP system, our website and the Flutter app.”
II“DUNA has been our long-term partner and has guided us through two website relaunches. The team also handles our ongoing website support and AWS management.”
III“We had to pull off a rebrand from Bitwala to NURI on short notice. Everything had to be new - including the website. As a neobank we have high demands on security, design and usability. DUNA took the job on very short notice and supported us well beyond the MVP.”
IV“To keep up with growing demand at consistent quality we work with DUNA. In DUNA we have a reliable partner that gives us the flexibility and scalability today's project business requires.”
V“When we were looking for a capable agency to create our new website, DUNA was highly recommended by another company. Finoa is managing assets, so security is highest priority for us. DUNA provided us with a convincing security strategy and a competent team.”
The studio
We look for companies with goals and a vision. Start-up or Mittelstand alike.
Tech feels like alchemy to most people. Done right, it produces gold - but the processes behind it look like magic. That is exactly where we come in: we build the technology and translate it into a language your business understands.
The name is the story: DUNA is the Hungarian name of the Danube. It rises in Germany and flows to Hungary - like our projects. German clients, a seasoned engineering team in Budapest, an office in Berlin. One continuous current instead of an agency relay race.

Frequent questions
What does a project cost with you?
Honest answer: it depends on scope. Smaller websites start in the low five figures, platforms and web apps above that. After the free first consultation you get a concrete, transparent estimate - no hidden items.
How long does a typical project take?
A marketing website: 4 to 8 weeks. A platform or web app: 3 to 6 months to the first live version. We deliver in sprints, so you see real results long before launch.
What does the collaboration look like?
A fixed team, one direct contact, weekly demos. You need no technical background - we translate every decision into business language.
Which technologies do you work with?
Modern and maintainable: TypeScript, React and Next.js, Laravel, Node.js, clean APIs and cloud infrastructure. We pick the stack for your case - not for our favourite technology.
Do you offer AI development and consulting?
Yes - from use-case discovery through prototypes to production LLM integrations, assistants and automation. And we tell you honestly where AI has no business case yet - before you burn budget.
Do you work with start-ups without a finished spec?
Especially then. We look for companies with goals and a vision - start-up or Mittelstand. The specification takes shape together in the discovery phase.
