Our prizes

Mathias Bork Knudsen, Head of Commercial Operations

When I joined the company, I did not quite know which direction I was going career-wise. I started out as a supporter, but quickly found out that I had a talent for sales, which I have subsequently had plenty of room to develop. Today I am in charge of operations and also handle sales, purchasing and servicing of large customers.
