ConcepttoCode

Custom software development for founders. We build your MVP from scratch, or turn a vibe-coded prototype into a product that can scale. 14 years, 59 projects.

What we build

Web & Mobile Applications

Web and mobile products built to launch fast and hold up under real users. For EyeLux, we went from a blank page to a live e-commerce platform in under two months, and it made sales on day one. We choose the stack that fits your product and budget.

Rescue & Rebuild

Inherited a codebase that keeps breaking, or a vibe-coded prototype that won't scale? We stabilise it, fix the architecture, and set up tests and CI/CD so your team can ship again. For Practivet, we turned an unstable veterinary platform into a multi-tenant SaaS.

Artificial
Intelligence

AI that does one specific job inside your product. We built the anti-cheating system that made SzuperChess's online tournaments trustworthy, and the company was later acquired. For the European Space Agency, our models estimate heat loss for every building in a city.

Data Platforms

Cloud platforms that turn large, messy datasets into dashboards and APIs your users can act on. We have built them for satellite imagery, sensor feeds and real-time telemetry, in projects for the European Space Agency, agriculture and marine monitoring.

Team Extension

Developers, AI engineers or full-stack specialists who join your team and work in your tools. You can start interviewing next week, and you pay only for the days they work. Auchan Hungary has worked with us this way since 2022.

How we work

Product strategy milestone markerProduct design milestone marker with light blue colourAgile development milestone marker

Strategy first

Whether you need an MVP for your first round, a demo for follow-on funding or a full launch, we start by agreeing on the milestone. Then we plan the shortest technical route there, so you spend less and launch sooner.

Design driven

Customers and investors judge a product in minutes, and the UX decides whether they stay. Our designers work alongside the engineers from the first sprint, so what we hand over is easy to use as well as good-looking.

Quality obsession

We use AI agents heavily and keep their code clean, secure and maintainable. Every change passes code review, automated tests and CI/CD. You test new features on staging first, and a warranty covers bug fixes after launch.
