About, team & founders

Who we are

Independent, senior and accountable.

Appsint is an independent Hungarian IT solutions and consulting company, founded in 2011. We design, build and operate complete business systems on our own proven low-code framework — wall-to-wall, from the first idea to years of operation.

We're a senior team with deep domain expertise across banking, energy, nuclear, public administration and EU-funded programs. The company was founded by two senior IT and business consultants who, after years inside large enterprise and government projects, built the framework they always wished they'd had — and a company to deliver complete solutions with it.

What we believe

Four values that hold up.

Sovereignty

Your software, your data, our IP. No foreign licence meter, no lock-in, full source-level control.

Accountability

One partner, from idea to operation. We own the outcome across the whole lifecycle.

Craftsmanship

Engineered to last. A stable, auditable backbone that carries regulated, mission-critical systems.

Long-term partnership

We operate, not just deliver — running and evolving systems for years alongside you.

By the numbers

Proof at scale.

How we engage

Two ways we work.

Direct delivery

We work directly with end-clients in the public sector and enterprise — owning the solution end-to-end, from conviction and requirements through build, refinement and years of operation.

Inside consortia

We act as the specialist delivery partner inside multi-party consortia — bringing the framework, the domain depth and the engineering backbone to large, regulated and EU-funded programs.

Most projects break on change. Ours are built for it.

Team

One team that speaks both languages: business and IT.

Appsint is a close-knit, senior team — people who have built mission-critical systems together since the company began. What sets them apart isn't a head-count; it's that every one of them is equally at home in the business domain and the technology, and personally carries a solution from the first conversation to a stable system in production.

How we are built

No translation layer between business and IT.

Most delivery problems live in the gap between the people who understand the business and the people who build the software — a gap usually bridged by hand-offs, written specifications and hope. Appsint is deliberately built so that gap doesn't exist. The same person who sits with a client to understand and formalise a requirement is also the person who designs the solution architecture and stands it up in our low-code framework.

That is only possible with a particular kind of colleague: senior, curious, and genuinely dual-fluent. Our developers are also business analysts; our analysts think in architecture and data models. When a client describes how their work actually happens — the exceptions, the edge cases, the regulatory constraints — the person listening already knows what it will take to build, and what it will cost to change later. Nothing is lost in translation, because there is no translation step.

It also means the team is dynamic in the way that matters: small decisions are made by the people closest to the problem, course-corrections happen in days rather than change-request cycles, and the person who promised something is the person who delivers it.

What every colleague does

From understanding the need to a system that performs.

Understand the real need

Sit with the client, learn how the business actually runs, and surface the requirements that paper specifications usually miss.

Formalise it together

Turn that understanding into a precise, agreed specification — written with the client, not handed to them — so everyone is building the same thing.

Design the solution

Shape the architecture and the solution design so it is good, efficient, stable and performing — engineered to carry real, regulated workloads.

Build and see it through

Stand the system up in our low-code framework, refine it against real feedback, and stay with it into production and operation.

The developer who is also an analyst

Dual-fluent by design.

In a conventional shop, a business analyst writes a specification and throws it over the wall to a developer. At Appsint that wall isn't there. Our low-code developers are themselves business analysts: they can run the workshop, model the process, and then build the working screens — which is exactly why our prototypes arrive in weeks and why change stays cheap. The framework removes the plumbing so our people can spend their seniority where it counts: on the business problem and the solution, not on boilerplate.

Continuity you can rely on

The people who started are still here.

Many of our colleagues have been with Appsint from the beginning, building the same kinds of mission-critical systems again and again. That continuity is not nostalgia — it is institutional memory. The patterns that make a banking back-office or a national programme dependable are held by the people who will design yours. When you engage Appsint, you get a stable, senior team that has solved your class of problem before and intends to be around to support what it builds.

How the work flows

One pipeline, from business need to running system.

We're organised as a single, continuous pipeline — not a relay of departments handing work over a wall. Because so much of a system is configured on a proven framework, the same dual-fluent people carry it from the first conversation to production, so the hand-offs that usually lose information simply don't happen.

Understand

Sit with you, learn the business, and surface the real requirement.

Design

Logical and solution design — process, data and architecture.

Configure

Assemble and parameterise on the framework — most of the system.

Build the custom

Engineer the genuinely unique parts and the integrations.

Run & evolve

Take it to production and keep it changing cheaply.

Spanning every stage: architecture standards, quality assurance, and DevOps to production.

Why it matters to you

A team that owns the outcome.

One accountable team

The people who understand your problem are the people who design and build it. No hand-offs, no "the experts sold it, juniors built it."

Both languages, one head

Business and IT fluency in the same person means faster decisions, fewer misunderstandings, and requirements that survive contact with reality.

Stable and performing

Every solution is engineered to be efficient, stable and fast under real load — not a demo that buckles when production traffic arrives.

Here for the long run

Long-tenured colleagues mean the knowledge behind your system stays with the team that built it, for years of dependable operation.

Founders

Built by the people who got tired of the old way.

Appsint was founded by two senior IT and business consultants who, after years inside large enterprise and government projects, designed the framework they always wished they'd had — and built a company to deliver complete solutions with it.

The origin story

It didn't start with a product. It started with a frustration.

Its founders spent the first decade of their careers as consultants and architects inside large, high-stakes enterprise and public-sector programs — banking back-offices, government information systems, regulated finance, document-heavy operations. Project after project, they watched the same failure pattern repeat, and it had nothing to do with how clever the technology was.

Requirements were planned on paper, by imagining the software. Business people were asked to specify, in detail and in advance, how software functions should behave — then those functions were designed on paper, signed off, and only much later built. But a business manager's job is to run the business well, not to design software. Asking them to picture a system they'd never seen produced confident specifications that turned out to be wrong the moment a working screen appeared.

Change broke everything. Real organisations don't hold still. Regulations shift, processes evolve, priorities move. In a paper-first, big-design-up-front world, every change re-opened the whole chain — re-specify, re-design, re-develop, re-test — and the budget and timeline paid for it. And feedback came too late: by the time end users and business managers could actually touch the system, the expensive decisions had already been made.

The founders concluded that the problem wasn't the people or the effort — it was the method. You cannot reliably design a complex system on paper with people whose expertise is the business, not the software. You have to let them react to something real, early and often.

So they imagined a different way of building: plan against actual functional skeletons, not paper abstractions. Stand up a working backbone fast, put real, clickable prototypes in front of end users and business managers in the first weeks, gather direct feedback, and let the system converge on what the organisation actually needs — while a stable, engineered backbone keeps the whole thing dependable under change.

That idea needed a foundation that didn't yet exist in a form they trusted, so they built one: a low-code framework (WSF — originally the Workflow Solution Framework) that could stand a real, working system up quickly, absorb change cheaply, and still carry the weight of a regulated, mission-critical deployment. They proved it across repeated client engagements — and then, in 2011, founded Appsint to develop the framework as genuine IP and to deliver complete, "heavyweight" enterprise solutions with it, wall-to-wall: from the first idea to years of operation.

That is still exactly what Appsint does.

We didn't want to write specifications for systems nobody had seen yet. We wanted to put something real in front of the people who run the business — in weeks, not months — and let them tell us what's actually right. So we built a framework that gives a project a stable backbone and an accelerated start at the same time: fast enough to show working software early and get direct feedback, solid enough to carry a central bank or a national program into production. Then we built a company to deliver complete enterprise solutions with it, end to end. That's Appsint.

Co-founder & CEO · Creator & principal architect of WSF · Senior IT consultant

András Nagy

András is the creator and principal architect of WSF (Workflow Solution Framework), Appsint's enterprise low-code platform. He conceived it, set its architecture and technical direction, and led its development. His career spans the full arc of enterprise IT — from IT strategy, systems design and integration through to hands-on build and rollout — and over two decades he has designed, built and delivered high-stakes enterprise and government systems: banking back-office, lending and risk workflows, fraud and complaint handling, electronic document management for a nuclear power plant, and national public-administration platforms, as lead developer and technical lead. WSF is the framework distilled from that work — and from years on the client side, assessing and quality-assuring the enterprise systems major vendors delivered into Hungary's largest banks and public institutions. His 2025 MIT Sloan AI credential underpins Appsint's responsible, enterprise-grade approach to AI.
