Kantoor Internetbureau Slik hartje Rotterdam

A Creative Digital Agency in Rotterdam

Founded nineteen years ago in Delft, Slik swiftly relocated to the vibrant city centre of Rotterdam.

At a few minutes’ walk from Rotterdam Central Station and the Schouwburgplein, and less than an hour from Amsterdam, we are easy to reach in every possible way. Being from Rotterdam, we use plain language, we love to cooperate, and we are nice folks to hang around with.
