Stroom

What Stroom does

STROOM is a Dutch full-service media and performance agency headquartered in Amsterdam with a secondary office in Rotterdam, operating as a subsidiary of Candid Group B.V. The agency sells integrated media strategy, planning, and procurement services underpinned by a proprietary methodology called MediaCommerce that balances short-term performance marketing with long-term brand building across online and offline channels. Its service portfolio spans media strategy, media buying across CTV, SEA, programmatic, and social, e-commerce and Direct-to-Consumer solutions, performance marketing, and a differentiated Closed User Group (CUG) marketing channel that reaches audiences through partnerships with loyalty platforms, savings programs, and member associations.

The agency's go-to-market is B2B and consultative, targeting mid-market and enterprise brands, with named customers spanning travel (Corendon), technology and navigation (TomTom), retail and furniture (Welvarend Wonen), construction and healthcare housing (Domuscura), photography (CEWE since 2019), energy (Innova Energie), food and beverage (Simon Lévelt), tools and manufacturing (Bosch Powertools), and cultural institutions (Rijksmuseum). It monetizes through professional services engagements—retainers, project fees, and hourly billing—rather than a self-serve or transactional model. AI is applied at an operational layer for campaign optimization and content generation, and via the AI Search Shift whitepaper co-developed with sister agency Modern Citizens.

STROOM is embedded in the Candid Group platform alongside sister agencies (Modern Citizens, mJourney, RLVNT, Positive, M2|OC) and was formalized in May 2026 as the media and performance bureau of Brand Potential, also within Candid. It has held Bureau van het Jaar recognition from MT1000, EMERCE, and FONK for four consecutive years through 2024, and operates in the Netherlands, Belgium, and—since January 2026—Germany.
