Friends

Friends

There are few companies where so many colleagues are also friends. That's our strength. Because friends only want the best for each other. Because together, we know more than we know alone. Because friends tell each other the truth. And because it's fun.

Friendship is based on equality. That's why ties are the least-worn items of clothing in the Coolblue office. Why you can tell the CEO what you really think of his new jacket. And why we talk to customers in an honest, open, and direct way.
