Sinergise is a Slovenian company based in Ljubljana behind Sentinel Hub, a service that makes satellite data from the Sentinel missions, Landsat and other providers accessible for browsing and analysis. This works in its cloud GIS or in the user's own environment. Features include full-resolution web preview, time-lapse, time-series statistics, area and point analysis tools, script-based custom products, reprojected WMS services and APIs. The documentation is moving to docs.planet.com, and the service is offered on the Planet Insights Platform.
Planet Labs PBC, a US company, acquired the business assets of Sinergise, including Sentinel Hub, in 2023. The acquisition ran through Scorpius Labs d.o.o., a subsidiary of Planet Labs Germany GmbH. According to Sinergise, Planet now owns and operates Sentinel Hub. The operating entity is therefore in Slovenia while the ultimate parent is in the United States. For European organisations, that US ownership is the relevant CLOUD Act signal.
