Ljubljana, Maribor · Slovenia
Working software
before you pay.
A custom software studio. You leave the first call with a working version of your idea, not a proposal.
No obligation, nothing to prepare.
Toni, Jakob and their team exceeded our expectations . With their ideas and responsiveness, we delivered the project faster than planned.
They didn't just build what we asked, they suggested improvements that made it even better . Deadlines respected, every request handled with real care.
The first major online quiz in Slovenia, where everything had to run to the second. And it did. Help and collaboration were always spot on.
They turned my complicated ideas into a turn-key solution , professionally and fast. Whatever came up, they fixed right away. My go-to IT team.
How we work

You click a working version before you sign anything. The first step is our risk, not yours.
01 A 15-minute call
Tell us what's slowing you down. No obligation.
02 Something you can click
Not slides. A working version, before you sign.
03 Progress every week
New work you can use. No months of silence.
04 One clear price
Known before we start. No hourly meter.
Our work
The projects we're proud of.
GZS Inovacije
Slovenia's national innovation awards, from the regional round in thirteen chambers to the national ceremony, on one platform we built and still run.
Planet Positive Sport
The platform FIVB uses to measure, review and certify the environmental footprint of volleyball events, with reports rendered by the server and AI run on our own GPU.
Olimpijski Kviz
A quiz played on ten thousand phones at once, in step with a live Winter Olympics broadcast, every night for sixteen nights.
Awards and competitions without the spreadsheets. Entries, judging by weighted criteria and results on one platform, built to your programme's rules and on your own domain.
The head start
You start weeks ahead.
Thirty pieces already built. Your investment goes into what makes you different.
SignatureThe toolkit all thirty pieces are written in. We wrote it, so nothing waits on someone else's release.
Open models on infrastructure we control. Your data stays private. No per-token fees.
Our own video and computer-vision engine. 17 AI models, no outside service.
We build software so that a mistake is caught while the code is being built, long before it can reach you or your users.
How we buildWe deliver working software in weeks, because every project starts on parts that already run in production and on rules that stop mistakes before launch.
How we buildA job that runs for an hour produces one result, even when the queue delivers it twice or a machine drops off the network halfway through.
How we buildHundreds of finished, narrated videos made from your own data, on a video engine and render machines we built and run ourselves, with nobody editing.
The founders
The two people who build it.
No business should have to bet on a promise.
FAQ
Fair questions, straight answers.
How is JT Digital different from an AI agency?
AI is our tool, not our business model.
JT Digital is a software studio: strategy, design, marketing, and engineering in one team. AI appears in two places in that work, and we treat them differently.
When AI writes our code, it writes against tools we built for it: our own framework, where a broken page, a wrong route, or an invalid style is a compile error. AI accelerates the work; the compiler decides what ships.
When AI runs inside your product, it runs on infrastructure we control: our self-hosted models and the Everyframe engine, EU-hosted, never behind a third-party API. Nothing you share leaves it.
An AI agency sells AI on a stack it rents. We ship complete products on a stack we own.
Can a small studio really ship complex products?
Yes. Our work already runs where failure is public.
Our quiz platform ran 16 live broadcasts on national television, built for 10,000 concurrent players and load-tested past a million requests with zero failures. The same stack runs the national innovation platform of Slovenia's Chamber of Commerce, a repeat client, and shipped a reporting platform to an international sports federation under a hard deadline.
A team this size ships that range because no project starts from zero. Every engagement begins on our production foundation: 30+ modules (auth, payments, analytics, email, video) extracted from our own shipped products and hardened by a nine-scope security audit. Your project starts where most projects end.
When a project genuinely benefits from additional expertise, we're honest about it from the start.
How do you ship so quickly without compromising quality?
We don't cut corners, we remove unnecessary work.
It starts with the people. Toni, co-founder and engineering lead, brings 10 years of software engineering and an MSc in computer science from the University of Ljubljana. Jakob, co-founder, has led 30+ software projects and scaled products from 100 to 80,000+ daily active users. Knowing which work is unnecessary is exactly what that experience is for.
Then comes the stack. We build on tools we own rather than tools we rent, which lets us bake quality into the build itself. fluent-html, our web framework, turns broken pages into errors we catch before launch instead of problems you find later. Everyframe, our video AI engine, applies the same philosophy to video.
AI accelerates execution. Experience ensures quality.
What do you build on?
TypeScript end to end. Fastify on the server, Postgres with Prisma, and server-rendered UI over HTMX, written in fluent-html, our own open-source framework, published on npm and now on its sixth major version. No React, no SPA framework, no client-side build.
It's a deliberately boring stack with one unusual property: we wrote the layer most teams rent. When the framework is yours, a broken page is a compile error, the styling system can't drift, and nothing in the chain waits on someone else's roadmap.
The AI inside our products runs on the same principle: the Everyframe engine and self-hosted models on EU infrastructure we control.
This site runs on that stack. So does everything else we ship.
Who will actually work on my project?
The people you meet are the people who build your product.
We don't hand projects from sales to account managers to junior developers. You'll work directly with the same senior team throughout the engagement, from strategy and design through to launch.
On every project that means Toni and Jakob, the founders. Toni architected the platform behind everything we ship; Jakob has led 30+ software projects to launch.
The names on the proposal are the names in the git log.
Can you work with our existing team?
Yes, with a clear division of work: your team owns the business side, we own the technical side.
We work closely with your product managers, designers, and domain experts. Their knowledge of your business shapes the product; ours turns it into working software.
What we don't do is join your development team or co-write a shared codebase. We cover the technical side in full: architecture, code, infrastructure, and quality. Every project starts fresh on our own platform, because a standard you don't control is a standard you can't promise.
How do projects and pricing work?
In three steps: a call, a prototype, and only then a price.
1. Discovery call. A 15-minute conversation about your challenge, no obligation. If we're not the right studio for it, we tell you straight.
2. Working prototype. We build something you can click before you sign anything. You judge real software, not a proposal document. If it misses the mark, you've spent 15 minutes; we've spent the build. The first step is our risk, not yours.
3. Scope and price. Once you've seen the prototype, we define the scope together and give you a clear, fixed proposal. You know the plan and the price before we start.
From there we ship in focused sprints, so you review working software, give feedback, and shape the product as it grows. No hourly black box, no surprise invoices.
