Our values



We encourage our people to be even more ambitious than we were when we created the company. This means pushing the boundaries of what seems at first impossible even further.


We want our people to be happy at work and after work.


People are happy when they feel they can be honest with each other without fear of being judged or reprimanded.


Being transparent starts by being honest with one’s self. If you cannot deliver on the deadline you promised or if you were wrong about something, it’s OK to say it and it’s even better to say it immediately. Saying “I don’t know” is fine, saying “I don’t know but I will look into it” is even better.


We highly encourage people to support one another. This means going the extra mile to help out someone even if it doesn’t have an immediate benefit for oneself.
