What B3Partners does
B3Partners is a Dutch open-source GIS (Geographic Information System) software and services company headquartered in Utrecht, founded approximately in 2003 (the company references 'more than 20 years' of operation). It develops and supplies interactive web applications for storing, publishing, and sharing geographic information, serving Dutch government organizations — primarily municipalities, provinces, safety regions, water boards, and engineering bureaus — together with selected commercial clients. The portfolio centers on two proprietary open-source products: Tailormap, a GIS viewer and publishing platform that lets organizations create branded internal or public-facing map portals, and BRMO-service (Basisregistratie MidOffice), a web application that fetches and centralizes the four Dutch national basic registrations (BAG addresses/buildings, BRK cadastral, BGT large-scale topography, NHR trade register) into a single geodatabase.
The underlying technology stack is Java/Spring Boot on the back end with Angular on the front end, containerized via Docker and integrated with GeoServer for spatial data services (WMS). B3Partners follows the Dutch government's Common Ground principles and avoids vendor lock-in by publishing source code on GitHub; the company is ISO 27001:2017 certified for information security management of its hosted applications. It is a founding member of OpenGeoGroep, the Dutch collaborative body for open-source GIS.
Revenue is generated through a mix of subscription-based SaaS/cloud hosting, implementation services, consultancy, support and maintenance, and customized training programs (typically 2-3 days per engagement), with quote-based pricing on multi-year contracts. Go-to-market is primarily direct enterprise field sales to Dutch public-sector buyers, complemented by community-led demand generation through open-source contributions, GitHub presence, LinkedIn, and the company website. B3Partners operates as a privately held BV (Besloten Vennootschap) with 11-50 employees, no disclosed external funding, and no M&A history.

B3Partners competitors and assessment
Company assessmentOthers
- QGIS: Open source desktop GIS project widely used in Dutch government and engineering bureaus. Adjacent open source ecosystem that B3Partners' products complement (via GeoServer integration) and partially compete with for GIS workloads.
- Geonovum: Dutch public foundation developing geo-standards and advising on basisregistraties and Common Ground. Not a commercial competitor, but a closely related ecosystem participant whose standards shape B3Partners' product roadmap and addressable market.
Broad incumbents
- Mapbox: Global mapping and location platform providing interactive map viewers and APIs. Comparable in the viewer/presentation layer that Tailormap occupies, though Mapbox is horizontal/developer-focused versus B3Partners' Dutch-government vertical specialization.
- Esri Nederland: Dutch subsidiary of Esri, the global proprietary GIS leader (ArcGIS). Serves the same Dutch municipalities, provinces, safety regions, and water boards that B3Partners targets, but with a much broader enterprise GIS portfolio — the principal incumbent competing against B3Partners' open source alternative.
- TomTom: Dutch-headquartered location technology company offering maps, navigation, and geospatial APIs. While focused on commercial/automotive location data rather than public-sector GIS, it shares the Dutch origin and broader location-platform overlap with B3Partners' map products.
Direct peers
- Object Vision: Dutch GIS specialist using its own GeoDMS platform for spatial data modelling and visualization for government and utility clients. Comparable niche GIS-vendor positioning in the Netherlands with a proprietary technology stack.
- Geodan: Dutch geospatial data and GIS solutions provider serving government, infrastructure, and mobility clients. Most directly comparable to B3Partners: similar Dutch market focus, comparable government customer base, and overlapping offerings in spatial data management and visualization.
Regional players
- Sweco Nederland: Large European engineering consultancy with a Dutch operation providing GIS, spatial planning, and infrastructure design services. Competes with B3Partners for engineering bureau and water board GIS projects, though from a much broader consultancy footprint.
