“Instead of wondering when your next vacation is,
maybe you should set up a life you don’t need to escape from.”
Seth Godin



Our office is equipped with the latest iMacs, gadgets, testing devices, development tools and high-speed Internet and newest technical stuff. On the 1st floor is a large work area with a total of eight workstations.


Above our bright and modern office, you will find on the 2nd floor the LOFT: Two separate living rooms, air-conditioned, one and a half bathrooms and a kitchen.


Our office is located directly next to a large park, the train station is only ten minutes walk away. Several main highways (A44, A 445, A2) connect Werl with the nearby Ruhr area and you will find two airports nearby offering direct flights to many European cities. 


Work has to be fun! Check out our office that comes with dartboard, sands bag, pull-up bar, sofas to chill and sometimes self-baked cakes or freshly made hot dogs. Around the inner city high street, which is within walking distance, you will find shops, restaurants and a bakery is just around the corner.
