STROOM & De Media Maatschap continue together


STROOM and De Media Maatschap (DMM) continue together under the name STROOM - Energy for growth. As of October 2021, DMM is affiliated with the Candid platform and the first steps have been taken towards a far-reaching collaboration with STROOM. The daily management of the new STROOM will be formed by Samantha Catsburg (Agency lead Rotterdam), Willem-Jan Nouwens (Agency lead Amsterdam) and Martijn Jaartsveld (Strategy Director).

DMM brings even more digital expertise to the new agency, especially in SEA and dashboarding. STROOM brings in extra brand and marketing communication expertise, in addition to media.


Samantha Catsburg: "We see many advantages because a synergy effect is created and because of that we can serve our clients even better. In a market that is becoming increasingly complex, partly due to consolidations and fragmented media consumption, it is important to be able to advise and assist clients fully. The scale makes it easier to invest in new services and products to make our customers grow."

High customer satisfaction

Willem-Jan Nouwens: "STROOM and DMM have a similar DNA. As a result, the integration of both agencies is smooth and feels very natural. We believe in short lines of communication with clients and therefore build long relationships. In addition, both agencies are known for their high customer satisfaction. This is reflected in the highest rankings in the annual customer satisfaction surveys of MT1000, Emerce100, Fonk and Adformatie, among others."

Media integration

Martijn Jaartsveld: "At STROOM we look for growth in brand awareness, performance and business results. This is not only about media, but we also analyze brand and marketing communication. Because the better we understand the entire communication strategy, the more effective the media advice will be. We do this in close cooperation within the triangle of client, advertising and media agency."

Offices in Rotterdam and Amsterdam

The new agency is based in both Amsterdam and Rotterdam for optimal national coverage. The agency focuses on medium to large national advertisers. The new STROOM consists of 30 client consultants who work daily on clients such as Hero Nederland, Decathlon, ENGIE, World Wildlife Fund, Dille&Kamille and The Royal Concertgebouw. STROOM is part of Candid: platform for growth.
