Frequently asked questions

You can find answers to frequently asked questions here.
How can we apply for the program?

No. You'll only receive the challenge at the kickoff. The Build Days are specifically for that: getting a taste, trying things out, doing.

Is it possible to participate only partially in the program?

Due to the large number of applications from highly motivated founding teams and the limited capacity of our Winter Batch, we expect active and full participation in the program.

What are the advantages of the program?

The program offers you the opportunity to learn the basics of founding a successful startup free of charge. By participating in the Demo Day, you will also get the unique chance to meet investors and win up to €15,000 in prize money. Click here to find out more about the added value of the program.

What is looked for in the application and what criteria must be met?

First, we check whether you are suitable for our program and whether the program can support you in the best possible way. We particularly pay attention to how innovative your idea is and your motivation for participating in the program. It is not a prerequisite that you have already founded a company. Individuals can also apply for the program.

Which topics will be covered?

As part of the program, you will learn about topics such as market analysis, product development, business models, finances, marketing, legal principles, financing, business plan preparation and much more.

When and how will we find out whether we can join the program?

We'll match you based on skills and preferences. You can also sign up as a duo or trio – we'll fill in the rest.
