Glesys is a Swedish-founded provider of colocation, cloud, and infrastructure-as-a-service (IaaS) headquartered in Falkenberg, offering VMware-based public/private cloud, dedicated servers, colocation cages and racks, and network/connectivity services across the Nordics and wider Europe. As of 2026 the company owns and operates six data centers itself — Falkenberg and Stockholm in Sweden, and Oulu, Helsinki, Pori, and Tampere in Finland — and extends its reach through partner facilities (Equinix Amsterdam, Equinix London, and a partner site in Oslo) plus points of presence including Frankfurt via sister company firstcolo. Founded in 1999 and majority-owned since 2023 by infrastructure investor Cube Infrastructure Managers (which also owns Germany’s firstcolo), Glesys has grown rapidly through acquisition, absorbing Portlane (2015), Moment Digital’s Tampere data center business, and in 2025–2026 Verne’s Finnish colocation operations in Pori, Tampere, and Helsinki. Its differentiator is a strong Nordic sustainability and data-sovereignty pitch: 100% renewable power, waste-heat recycling into district heating networks, and an EU-only jurisdiction model, alongside a newly announced AI-ready campus in Oulu planned for up to 300MW of capacity.
GleSYS operates as a cloud provider and colocation provider, with facilities at the following locations:
