Would you like to rethink
Trading with us?

Our challenge

As Germany's leading broker we constantly work hard to improve customer experience for our customers. This is why we are eager to see if you are accepting the following challenge:

„90% of Germans do not own stocks and/or have not a affinity to that subject.

Your challenge is to build cool apps that make trading easy, attractive and fast for those 90%.“


Breaking the mold, rethinking trading. How could the "trading of tomorrow" look like? Amaze us!

Done differently

Don't dip into the past regarding trading experiences. Create something different that delights traders of tomorrow.

Easy UX

Simplicity is king! How could trading be done easy? Use modern UX!
