Why us
Looking for an app developer in Amsterdam? We guide the full process from first sketch to publication in the App Store and Google Play: technical advice, design, development, testing and maintenance after launch.
Our office is on the Westblaak in Rotterdam and the train to Amsterdam takes fifteen minutes, so we are there when it matters. The rest of the time we work the way most Amsterdam clients prefer: fixed contact moments, a demo after every round and one point of contact who knows the project inside out.
What we build
Amsterdam is one of Europe's most dynamic startup and scale-up ecosystems. We understand the pressure that comes with it: moving fast, keeping budgets tight and shipping a product that works from day one.
We build cross-platform apps with Flutter: iOS and Android from a single codebase. That saves on development time and maintenance, and you keep a single team at the wheel. Only need an iOS app, or would you rather start with Android? We advise on that per project.
Not every problem calls for an app in the store. For a customer portal, a dashboard or an internal tool we build a custom web application, hosted on Google Cloud so it scales with you. We take care of the backend and APIs ourselves, so you keep a single point of contact for the whole technical picture.
Many clients are not looking for a consumer app but for a business app that speeds up an internal process: taking orders, recording inspections or supporting staff in the field. That is the type of app we build most often, and it pays for itself in hours saved.
Whether you want to validate a first idea or expand an existing system: we adapt our approach to your phase. We give honest advice on scope and costs, even if that means recommending you start smaller.
A great app also needs to be found. We advise on App Store optimisation so your app is discoverable from day one on the keywords that matter to your audience.

Get started
An introduction can take place at your office in Amsterdam, at ours in Rotterdam, or simply over a video call. You decide what works best.
Tell us what you have in mind and we will give you an honest view of what it costs, how long it takes and whether the idea is worth building in this form. Even if the conclusion is that you are better off starting smaller.

FAQ
Yes, absolutely. We work for clients throughout the Netherlands, and Amsterdam is one of the cities where we regularly have projects running. Most of the collaboration happens fully remotely via video calls, email and our project environment. That works well: you get a dedicated contact person who monitors progress and gives you a demo after every round.
Prefer a face-to-face meeting? We come to Amsterdam, or you are welcome at our office on the Westblaak in Rotterdam. Location is no obstacle for us.
Our office is at Westblaak 33 in Rotterdam, fifteen minutes away by train. We deliberately do not run a second branch in Amsterdam: we would rather keep one dedicated team in one place than spread offices with rotating staff. That is why you always have the same developers on your project.
It changes little for you. We travel to Amsterdam for introductions, workshops and any moment where meeting face to face helps, and in between we work with fixed contact moments and a demo after every round. You are always welcome on the Westblaak as well.
Yes. Alongside mobile apps we build custom web applications: customer portals, dashboards, planning tools and internal systems that run in the browser. For many problems that is the better choice than an app in the store, certainly when your users sit behind a desk or when you want to ship updates without an Apple or Google review.
We develop with Angular and NestJS and host on Google Cloud so it grows with your business. Read more about having a web application built, or bring your case to an introductory call. We will tell you honestly whether an app, a web application or a combination delivers the most.
That is the largest part of our work. Think of apps that let staff record inspections on location, take orders or handle their work orders, often connected to systems you already use. These apps rarely have thousands of users, but they do save hours of manual work every week.
We build them for Amsterdam scale-ups and larger organisations alike. Read more on our page about having a business app built.
The cost depends on the complexity, the platform and the number of features. A simple app starts from €10,000; a platform with multiple user roles, a backend and external integrations can quickly reach €30,000–€60,000 or more. We primarily build with Flutter, which lets us develop iOS and Android from a single codebase — cheaper than two separate native apps.
After a no-obligation introductory call we provide a transparent quote per phase, so you know exactly where you stand.
Yes. We built the Spotted by Locals app, a travel guide for locals in cities including Amsterdam. We also built the Incision Academy platform for Amsterdam medtech startup Incision, an e-learning platform for surgeons used worldwide. We also built an app for Medimo, a medication management platform in healthcare, and a stakeholders app for the Dutch Banking Association.
Every project started with a no-obligation conversation. View the full portfolio on our cases page.
Fully remotely, but with the short lines of a local partner. We work with fixed contact moments, weekly updates and demos after every round. You always know where the project stands and can steer when needed. We use a shared project environment so you have insight into the planning and progress at any time.
Prefer to meet in person occasionally? We regularly travel to Amsterdam, or you are welcome at our office in Rotterdam.
Yes. We work for both startups and larger organisations. For startups we actively help scope the MVP: which features are truly needed to validate the concept, and which can wait? This prevents unnecessary budget being spent on features the end user may not need at all.
An MVP starts at €10,000 and can go live within two to three months. Don't have a fully worked-out idea yet? No problem. We help you make the idea concrete during an intake call.
Let's grab a coffee. Tell us about your idea and we'll give you our honest take on what's possible.
