creativity with a capital c


In what once was the centre of the Amsterdam diamond trade, you can now find the new creative hub of the city: Capital C. Here, on the banks of the river Amstel, we support creatives of every level and celebrate creativity of all kinds.

At Capital C, we know that creativity is not a mysterious gift that some people have and others don’t. Rather, we understand that creativity is an undefined sum of intelligence, professionalism, dedication, humour, social skills, confidence and sometime just dumb luck.

We understand that you sometimes need to think up 567 horrible ideas before you come up with something brilliant, or at least, something potentially brilliant. At Capital C, we offer space for the 567 horrible ideas and for the one idea that just might change the world – or your world.

By providing space to meet, work and collaborate, Capital C unites fresh academy graduates with famous established creative professionals, links freelancers to agencies, and connects creativity and commerce. We believe that this energy makes Amsterdam a city of international connectivity and infinite possibilities.

You’re free to call it whatever you want.
We call it creativity with a Capital C.
