Sourcepole AG is a GIS service provider based in Zürich that delivers services around QGIS and open-source web mapping. Its offering includes QGIS Enterprise, a maintenance and support package for spatial data infrastructures built around QGIS Desktop, QGIS Server and the QGIS Web Client; QGIS Cloud, which publishes QGIS maps to browsers and mobile clients through OGC WMS and WFS services; and hosting, advice on spatial data infrastructures and custom solutions built on open-source components.
The company is based in Switzerland, outside the European Union. Its imprint lists Sourcepole AG in Zürich and names no parent company. According to its hosting page, the servers run in Europe and hosting in Switzerland is available on request, so an organisation with a Swiss residency requirement should ask for that option explicitly. QGIS itself is open-source software, so an organisation can also operate it on its own infrastructure; the choice between Sourcepole's hosting and self-hosting is then a procurement question.
