Web development in Delft.

Web development in Delft means building web applications, SaaS products and AI systems for a city entirely focused on technology. TU Delft is an engine for deep-tech, engineering and hardware startups, and incubators like YES!Delft make sure research grows into companies. Those teams are technically strong and look for a build partner who thinks along at the same level.

NedDev works as a The Hague studio for clients in Delft, and Delft is so close that we are practically neighbors. Some of our clients studied at TU Delft, and we speak the language of engineers: precision, reproducibility and architecture that holds up.

For companies in Delft we typically build:

• SaaS platforms for deep-tech startups that turn their technology into a product.
• Dashboards and software around hardware, sensors or measurement data.
• AI applications where reproducibility and control come first.

Delft is perhaps the most technical city in the Netherlands. Around TU Delft and YES!Delft, startups emerge that come out of serious research: robotics, energy, materials, sensors. The founders are often engineers who know exactly what they want and who value precision. Anyone building for this market has to deliver software that not only works, but is also reproducible and verifiable.

That is exactly how we build. For deep-tech startups we use our multi-tenant SaaS architecture, so a product can grow from the first customer without a rebuild. For applications with AI we value determinism: in AI development we replace the guess of a model with a fixed calculation where possible, so the same input always produces the same result.

Our technology is complex, do you actually understand what it is about? We do not build the physics, but we do build the software around it, and we are glad to dive into the details. For JinSulate we built a system that reads construction drawings geometrically, so we are used to technically substantive projects.

The City of Delft positions itself as a technology city, see delft.nl. How we secure reproducibility in a technical product is shown by JinSulate, where a geometric counter replaced the loose AI estimates so results always come back reliably.

Delft is about a fifteen-minute drive from our studio in The Hague. That is so close that sitting at the table is never a hassle. We come over for the kick-off, for design sessions and for the go-live, and we can switch gears quickly in between if a topic calls for it. For the intensive early phase of a deep-tech product, where many choices are made, that proximity is valuable.

We build our frontends on Next.js, for fast and easily findable interfaces, with Laravel or FastAPI on the back end. That consistent stack ensures a product stays manageable even after delivery, which matters for a growing startup.

A Delft project usually runs like this:

1. A sharp scoping of what the product has to do and how you measure success.
2. A working prototype on real data or real usage, not on a test set.
3. Building in sprints with weekly demos, with time at the table where it helps.
4. Going live with the chain production-ready: logging, limits and checks.

Many TU Delft alumni register their first company at the Chamber of Commerce and then look for a build partner who can handle their ambition. For such teams a well-defined first platform is the smartest start, and the short distance makes close collaboration easy.
