Dietz Strategie & Communicatie

What Dietz Strategie & Communicatie does

Dietz Strategie & Communicatie is a privately held Dutch strategy and communications consultancy founded in 2006 and headquartered at Bemuurde Weerd O.Z. 37 in Utrecht. The firm specializes in complex spatial and societal challenges in the Netherlands, advising on area development (gebiedsontwikkeling), public participation, process management, coalition building, and implementation of the Omgevingswet (Environmental and Planning Act). Clients include Dutch municipalities (e.g., Gemeente Bergen, Den Haag, Vijfheerenlanden, Heemstede, U10 region municipalities), national government bodies (Rijksvastgoedbedrijf), housing corporations (Woonbedrijf Eindhoven), private developers (BPD, Dura Vermeer), industry associations (Woningbouwers NL, SKG), and societal organizations. The firm reports a track record of more than 200 area development projects delivered over nearly 15 years.

The firm's technical and methodological assets center on two proprietary frameworks: the Diabolo-model, a participation methodology developed over 14 years for engaging target groups in complex processes with balanced attention to input collection and feedback, and the Urban Concepting-model, used to research spatial development opportunities from a sustainable vision. These underpin a service portfolio structured around five core practices (Area Development, Participation, Process Management & Decision-Making, Coalitions & Alliances, Omgevingswet in Practice) and supplemented by brand strategy products (Merkstrategie, Merkboek, Merkpaspoort, Merkkompas, Merkactivatie), communication services (crisis communication, campaign advisory, environmental communication), and specialized tools (De Omgevingsmonitor monitoring tool, Onderdompelweek immersion program). The team consists of approximately 12-14 senior strategists and advisors with backgrounds in government, politics, and spatial planning.

The business operates as a professional services firm with sales-led, relationship-based go-to-market motion. Revenue is generated entirely through consulting engagements, with services priced on a quote basis tailored to project complexity. Marketing is content-led via a website with project showcases and whitepapers, an active LinkedIn presence, the "Planologisch" podcast, YouTube webinars, and participation in industry events such as SKG congresses. As of March 4, 2025, the firm is jointly owned and led by Jasper Benus (Algemeen directeur & partner) and Marte Kappert (Directeur & partner), who completed a management buy-out acquiring the remaining shares from founders Luc Dietz and Stella de Heij. The firm operates exclusively within the Netherlands.
