Companies that trust us
Just 15 km from Delft
Our office is in Rotterdam, just 15 km from Delft. We can quickly be on-site for an introductory meeting, demo or working session.
Flutter specialist
We were among the first agencies in the Netherlands to use Flutter, where one codebase serves both iOS and Android.
Dedicated contact person
You discuss your project with the developers who build it, and they stay the same people from start to finish.
Why us
In Delft you'll find technology companies, knowledge institutions and startups with strong ties to TU Delft. We build apps for these types of clients: from geo-information systems and inspection apps to B2B platforms and customer portals.
Our office is at Westblaak in Rotterdam, just 15 km from Delft. We are quickly on-site for a meeting or demo, with the rest of the collaboration running via fixed online contact moments.
Our approach
A geo-information app or inspection tool runs on data from other systems, so the integrations get as much attention as the interface.
Engineers, researchers, customers or field workers: the design starts from who will use the app.
With Flutter we build a single codebase for iOS and Android. One codebase means lower costs and a shorter lead time, with the same quality.
We connect the app to your existing software: GIS systems, databases, APIs or cloud platforms on Google Cloud.
After launch you can keep calling on us for updates, new features and performance improvements.

FAQ
Yes. We work across the Netherlands, and Delft is just 15 km from our office in Rotterdam. That means we can visit you quickly for an introductory meeting, demo or working session.
You are also very welcome at our office at Westblaak 33 in Rotterdam.
Location has no effect on the price. A first version with core features only (MVP) starts from €10,000 and a basic Flutter app from €15,000. A platform with multiple user roles, a backend and integrations can quickly reach €30,000 to €60,000 or more. We build with Flutter, which lets us develop iOS and Android from a single codebase.
After a no-obligation introductory call we send a quote that shows the cost of each phase.
Yes. We built the Perceelwijzer for the Unie van Waterschappen, a geo-information app for water management across the Netherlands, and the MasterCheck app for Acidus, an inspection platform for technical checks.
Technical applications have to be reliable, work offline and integrate tightly with data from other systems. Sometimes specific security requirements apply as well. We take all of that into account from the design stage.
Geo-information systems, inspection tools, B2B platforms, government applications and internal business tools, among others. If it is custom work, we can build it.
All projects are on our cases page, and each of them started with a no-obligation conversation.
Yes, with both, and with larger organisations too. TU Delft Valorisation supports spin-offs with funding and guidance; we take care of the technical execution. We help you sharpen the MVP scope by looking at what the end user actually needs and what can wait. An MVP starts at €10,000 and can go live within 2 to 3 months.
