Fixed-price app & web development in 4 steps

After 200+ projects, we know how to make the leap. Four steps take you from your idea to a finished app or web platform.

  1. Project check & introduction

    free

    We get to know your project, and you get to know how we work. Ask us anything. We'll explain the project stages and what's realistic. If we're a good fit, we move on to the workshop together. Book your free call now!

  2. Workshop

    Here we explore your idea in depth. We create several initial concepts, map out a clear user flow and give your idea structure. At the end, we summarise everything in a debrief so both sides know whether and how to move forward together.

  3. UX/UI design & prototype

    From here, we work closely together each week. You share your input. We develop designs, sharpen the user flow and refine every detail. Calls and Figma comments keep you involved throughout, until the design is fully thought through and ready for development.

  4. Development & launch

    We build your product with React, React Native and modern cloud technologies such as Supabase, Firebase or Railway. You get regular updates through TestFlight and clear recommendations on how to build features well. Fixed-price development, with no surprises.

For founders & startups

If you have an idea, we turn it into more than an app. We help build a startup that brings your vision to life. We don't just build, either. We help you make important decisions about your product, marketing and building a business.

For businesses & scale-ups

Your app or software works, but it may have lost its edge. We bring a startup mindset to your existing product and help it move forward. Not a complete restart, but a considered evolution built on what already works.

Where your business stands today is just the beginning.

You've built something strong, but inefficiency is slowing you down. Quality is slipping and timelines are stretching. It's time to regain your focus and momentum.

  1. 01

    Are your designs falling behind the competition?

  2. 02

    Does your development process feel inefficient?

  3. 03

    Does your development team lack clear direction?

Still have questions? Here are the most important answers

How much does it cost to develop an app or web platform?

Costs depend on the scope, features and technical complexity. Our workshop helps us assess a realistic budget for your project early on. Find out how we build browser-based platforms and what they cost on our web app agency page.

How does a project with you work?

We always start with a free introductory call. Next comes a workshop where we work on the structure, user flow and initial concepts. Only then do we move into UX/UI design, followed by development.

Can you handle just the design or just the development?

Yes. We can take projects from idea to launch, but we also handle individual parts such as UX/UI design, product refreshes or development for existing products.

How soon can you start my project?

We can usually start within a few days, provided we have capacity. After the introductory call, we can tell you directly when your project can begin.

Am I in the right place if I'm still at the very beginning?

Yes. Many of our projects start with an idea and no finished concept. That's exactly what our workshop is for: developing structure, priorities and a clear plan.

Let's talk about your project

In 30 minutes, we'll clarify where you are, what you need and what's realistic. It's free, with no obligation. Afterwards, you'll receive a fixed-price quote.

We look at your plans with you as if they were our own. If building does not pay off, we tell you, even when that speaks against the project.
