Mission Statement

Our Values - According to which We Act with Each Other, with Our Customers and Partners


Trust over control

For us, trust is the basis of good cooperation. We treat each other as well as our customers and partners as equals, we are transparent and honest. In projects, we actively contribute our professional opinion, think along and question.


Passion over degrees

We are passionate about developing unique solutions that inspire. Our fire for new technologies can hardly be tamed and we are constantly educating ourselves to stay up to date.


Mass customization over mass production

Our solutions are creative and innovative, as is our approach. We work agile and develop individual solutions that go beyond the usual standards in terms of technology and design. This is how we create a user experience in every project that inspires.


Following the team over freedom and independence

Freedom and personal responsibility enable the whole team to organize their work according to their own needs and thus always get the best out of it. The team is above everything.


Responding to change over following the plan

Sitewerk is free from stubborn processes and rusty structures. Focused but dynamic, we are gradually working towards our vision.
