JSO

What JSO does

JSO (Stichting JSO) is an independent Dutch advisory bureau specialising in the social domain, headquartered at Zuid-Hollandlaan 7 in The Hague and operating exclusively in the Netherlands. Founded in 1975, the firm has over 50 years of accumulated experience working with municipalities, execution organisations, collaboratives, and ministries on participation, neighbourhood-oriented work, youth, and healthy living. JSO positions itself as a bridge between residents' lived experience ('leefwereld') and the institutional policy system ('systeemwereld'), with a stated mission of building communities where everyone can participate, feel connected, and be of significance.

The firm's offering consists of six interconnected advisory services — project and process management, organisation and team development, action-oriented research (actiegericht onderzoek), interim management, methodology development, and impact monitoring — delivered across four thematic areas: participation, neighbourhood working, healthy and active living, and youth. Differentiating methodologies include actiegericht onderzoek (where learning and doing happen simultaneously with residents, professionals, and policymakers), Deep Democracy facilitation, and the Doelenboom (goals tree) impact-monitoring tool. The firm also co-develops client-specific methodology guides, such as the Werkwijzer Ervaringsdeskundigheid produced with Blijvend Veilig Amsterdam for integrating experiential experts into child-protection teams.

JSO is structured as a Dutch foundation (KvK 41125249) that transitioned in 2008 from a subsidy-dependent entity to a self-sustaining advisory bureau operated by entrepreneurial consultants. Revenue is generated entirely through professional-services engagements sold directly to public-sector and social-sector clients; project-based invoicing is structured as 50% at commencement, 40% mid-project, and 10% on completion for engagements of two months or longer, with single invoices issued for shorter projects under €5,000. With only 1–10 employees, the firm operates at boutique scale, relying on content marketing, LinkedIn, and direct relationships rather than any software platform or self-serve channel.

Core offering

JSO provides advisory and consulting services in the Dutch social domain, including project and process management, organisation and team development, action-oriented research (actiegericht onderzoek), interim management, methodology development, and impact monitoring. Engagements are delivered directly to municipalities, execution organisations, collaboratives, and ministries across thematic areas of participation, neighbourhood work, youth, and healthy living.

Product overview

JSO is an advisory bureau in the social domain that operates as a single, unified consulting offering rather than a software platform. The company provides six interconnected advisory services: Project- en procesmanagement, Organisatie- en teamontwikkeling, Actiegericht onderzoek, Interim, Methodiekontwikkeling, and Impactmonitoring. These services are delivered across four thematic areas: Participatie (participation), Werken in de wijk (neighborhood work), Gezond en actief leven (healthy and active living), and Jeugd (youth). Rather than a modular software product, JSO offers expertise-driven consulting engagements where advisors work collaboratively with municipalities and social organizations to strengthen communities.
