A studio that runs its own software.
We are a software studio in Zagreb. We build custom software, web shops, automation, integrations and AI agents - and we run five live products of our own.
Who we are
Tsunami Digital is a software studio based in Zagreb, Croatia, founded in 2026. We design, build and maintain custom software for businesses of every size: web and mobile apps, web shops, process automation, integrations and AI agents. We work in English and Croatian, with clients in Zagreb, across Croatia, throughout the EU and worldwide, and as the engineering partner behind agencies.
Alongside client work, we build and run five products of our own, from a Sunday store finder used by more than 300,000 people a month to a services marketplace and a grocery price comparison platform. Nobody hands us a spec for them. We decide what to build, keep them online, fix what breaks and live with every shortcut we take.
That shapes how we work for clients. The code we hand over is held to the standard we rely on ourselves: tested, documented and built to be maintained. Every project follows the same four phases - Research, Design, Build, Operate - and we stay on after launch, because we know from our own products that software is never done on release day.
What you can count on
04- 01
Price agreed up front
Every project depends on its scope, so we agree the price in writing before work starts. No surprises along the way.
- 02
You own the code
Once the work is paid for, the source code, data and design files are yours, in your own accounts. No lock-in, no kill switches.
- 03
Plain language
Most of our clients are not technical. We explain decisions and trade-offs in plain words and document every choice.
- 04
Built to be maintained
We use modern, actively maintained technology picked for the problem, so your software stays easy to run and to hand over for years.
How we work
-
Research
We pin down the problem, constraints, and success metrics - one week, fixed scope, written brief.
-
Design
Every important decision happens before code - how it looks, how it works, how it all fits together.
-
Build
We turn the plan into working software - tested, documented, and ready to use on day one.
-
Operate
Steady oversight, regular updates, and continuous improvements - your software stays sharp and reliable.
Let's build the next wave together.
