Software studio · Graz, Austria
Websites, custom software, artificial intelligence and blockchain — built in Graz, Austria, for businesses that need more than something off the shelf.
01 — Websites & web apps
Built from the ground up — no theme, no page builder, no forty plugins slowing each other down. What you are looking at was written for you.
You do not have to take our word for it. This page is measuring itself right now — on your device, on your connection.

Thresholds follow Google Core Web Vitals. The values are produced in your browser and never leave it — we never get to see them.
The site that convinces your customers before you have spoken to them.
Customer portals, booking systems, internal tools — in the browser, nothing to install.
Sell without paying every month for features you will never use.
A legal requirement for many businesses since June 2025. We build to it from the start.
02 — Custom software
When your process does not fit an existing product, we build the product. Four layers, cleanly separated — so that in five years someone can still change something.
One interface per role rather than one for everybody. Fully keyboard operable, as usable on a phone as at a desk, and labelled in the words your staff actually use.
Discount tiers, approvals, deadlines, who-may-do-what: written once, enforced everywhere. When a rule changes it changes in one place — not across four forms and a spreadsheet.
Nothing is silently overwritten: who changed what, and when, stays traceable. The database runs wherever you want it to — and the export belongs to you, not to us.
Your accounting, your inventory system, your till, your inbox. What exists gets connected rather than replaced — we only retire what you want retired.
Sprawling spreadsheets become a system several people can use at the same time.
Quotes, invoices, reminders, reports — defined once, then handled for you.
Two programs that refuse to talk to each other start talking to each other.
Your developer is gone and nobody dares touch the code? We have seen it.
03 — AI solutions
Not every problem needs a language model in someone else's cloud. Plenty runs faster, cheaper and more privately on your own premises — or, like this one, right in the browser.
Here is one. It sorts messages onto departments, and keeps learning when you correct it.

Sorted it wrong? Tell it where this belongs:
Logistic regression over hashed word and character trigram features, in JavaScript, about 6 KB. No model download, no API key, no request to any server — your text never leaves this tab. Reload the page and it forgets everything.
Incoming mail, forms and tickets land with the right person automatically.
Invoices, delivery notes, contracts — extracted, checked, pushed into the system.
Answers from your manuals and records. Not from half the internet.
On your own hardware, when the data is not allowed to leave the building.
04 — Crypto & blockchain
Blockchain is rarely the answer. When it is, you get more than the smart contract: the interface, the wallet integration, the migration of existing holdings, and running the thing afterwards.
The numbers below come live from the Ethereum chain — fetched by our server, not by your browser.

The call goes to dezwart.at/api/chain. The RPC provider sees
our server — it never gets to see your IP address.
That detour is the entire point: most wallet and token front-ends talk to a third-party provider straight from the browser, handing over every address their users look at.
Design, implementation, tests, and getting you ready for an external audit.
Issuance, distribution, and the delicate part: moving holdings cleanly onto a new chain.
Lock-ups, payouts, auditability — as a system, not as a spreadsheet.
Signing, approvals, swaps — in an interface a non-expert can actually operate.
Work
No wall of client logos. Two things we built from the first line through to running them in production — which is a far better picture of what you would actually get.
Editor, terminals, git, workspaces — and a whole fleet of AI agents that build, review and ship code. The real trick sits underneath: every feature also exists as a command-line verb, an HTTP API call and an MCP tool. Nothing is human-only, so an agent can drive the interface exactly as you would.
Live standings, player profiles, match history, tier lists and a draft simulator for an esports community's leagues. Kills, damage, win rates — collected continuously, crunched, and presented so that thousands of people can read something out of it without a manual.
Client work is under confidentiality and therefore not listed here. We are happy to talk through what it involved.
How we work
You need no specification document and no finished idea. A problem is enough.
01
One conversation, free and without obligation. Afterwards you know whether it pays off at all — including when the answer is no.
02
Something clickable every few weeks. Not six months of silence and the wrong product at the end.
03
We keep running and maintaining it if you want us to. If not, you get the source code and the documentation and carry on yourself.
Frequently asked
If your question is not here, just put it in the form below.
We do not publish flat prices, because for bespoke software they would always be wrong: a single campaign page and a customer portal with role-based permissions have nothing in common. What we do instead: a free first conversation to establish scope, then a written quote with clearly separated line items.
If it turns out that an off-the-shelf product solves your problem more cheaply, we will tell you so.
A manageable company website is usually a matter of weeks; a web app or custom software, a matter of months. More important than the total is that you have something usable in hand every few weeks — that way you can steer early, instead of discovering at the end that you needed something else.
We are based in Graz and happy to meet in person across Styria. Otherwise the work is remote, which works just as well across Austria, in Germany and in Switzerland. Consulting and project delivery are available in German and in English.
A standard product is cheaper for exactly as long as your process happens to fit it. The moment you start bending your process to the software, buying add-on modules, or plugging the gaps with spreadsheets, you pay the difference anyway — just spread out and permanently.
Custom software pays off where your process is a competitive advantage, and therefore nobody should be flattening it.
Usually you do not, and we will say so. AI pays off where people make many similar decisions — sorting mail, extracting documents, answering recurring questions, forecasting demand. Where the rules are exact, ordinary software is cheaper, faster and easier to account for.
The classifier further up this page is an example of the small, cheap kind: no language model, no cloud service, a few kilobytes, and it runs in your browser.
Yes. You get the source code and the documentation, and you can take them to any other developer. We do not build anything that chains you to us — no obfuscation trick, no licence file, no exclusive hosting.
We do, if you want that: maintenance, updates, monitoring and further development. Equally, you can take it in-house or hand it to someone else — which is why we write code a stranger's team can read, and document it accordingly.
Yes, and it is a common case: the original developer is gone, nobody dares touch the code, and something still has to change. We look at what exists, tell you honestly whether repairing or rebuilding adds up, and then take over running it.
Contact
One message is enough. You get a reply from the person who would do the building — no sales team in between.
