What customers say.

Our Services
UX/UI Design Icon
UX/UI Design
Design is more than look and feel. It defines how users navigate and experience applications and if we make that a pleasant experience, they will come back. That’s why we analyse the data, make it interactive, test prototypes, and yes, we will make it pretty.
Web Development Icon
Web Development
Anything from a simple portfolio website to a fintech platform, you name it, we’ve done it. We can deliver what you need faster than you can say „Oachkatzalschwoaf“ (to save you the trouble of googling it: it’s German for squirrel’s tail).
App Engineering Icon

There is no greater compliment to your business than a customer coming back to do another project.

Our mission at 9Y is to advance the state-of-the-art of building digital products

Our way of doing that, is to put people first. You can call that our core strategy. Almost any decision we make, can be traced back to this belief that if you put people first–and build a place where the best people want to work–that good things happen. This belief drives most of our policies. One example of many is our commitment to transparency including publishing our playbook open for the world. We summarise this belief by saying that we put „relentless focus on the people behind the products“. This is what defines us and we think also sets us apart.
