Custom backends for agencies & UI teams

You already have your own frontend team or would like to hire an agency for it? Maybe you are an agency looking for a strong backend partner?

You focus on creative ideas. We create custom backends for your use case - so that your solutions adapt to you, not the other way around.

You want something unique?

We can help. In times of skills shortages and resource constraints, it's a challenge to assemble a competent project team.

You don't have to take that on yourself - we already have professionals on board who have years of experience in backend development and are constantly improving.

  • We build what you need. Individually adapted to your processes and needs.

  • You can focus on the frontend and end customer processes.

  • We provide scalable and stable backends.

You already know that you need an individual solution, but you still have no idea which variant is the best for you? Whether it's a platform, portal, marketplace, store or something else entirely - we'll explain the advantages and disadvantages of the different variants and help you find the right one.

What can our custom backend do?

Custom APIs for your project

You want to build a new system and take care of the frontend yourself? Or you have a partner for this, but need support with the backend?


While you take care of the frontend, we secure all necessary backend functionalities - using REST APIs.

We build our solutions to be fast, secure and scalable.
