What does Ostendis mean and what prompted us to name the company Ostendis? Ostendis is derived from the Latin and means “to show or present oneself”. Ostendis is the conjugated form of the verb ostendere in the 2nd person singular present indicative active, i.e. the DU form. And that’s exactly why we find the name very fitting and original. How nice that you are interested in it too!
