A Little about SimpleSite:

123hjemmeside was founded in 2003 in Copenhagen. Today, we are an international company growing rapidly. In connection with our international growth, we have just brought together all of our local brands under one brand – namely, SimpleSite. We create a super easy and user-friendly website builder for non-experienced users. Four to five million people create a website with us every year, and we have a fast-growing client base from all parts of the world. An ambitious strategic plan for further expansion has been scheduled, and our goal is to become one of top three world leaders in our field.

To address this ambition, we are now expanding our staff in Copenhagen with three very central and important key positions essential to the business. You will gain more than 20 colleagues in our office central in Copenhagen, and in addition, you will be linked to around 30 colleagues in other locations. Our environment is very innovative and at the forefront of technological development. You can read more about us on:
