Proxmox

Proxmox Server Solutions GmbH is based at Bräuhausgasse 37, 1050 Vienna, and was founded in 2005 by brothers Martin and Dietmar Maurer. It publishes Proxmox Virtual Environment, Proxmox Backup Server and Proxmox Mail Gateway, all under the AGPLv3, and sells optional support subscriptions rather than licences.

The company has taken no venture capital. Its own company page states that Proxmox “is an independent and profitable company, with our customers and supporters as our only investors”, and the Austrian commercial register shows no corporate shareholder above it. Subscription terms name the Vienna entity as the contracting party and vest exclusive jurisdiction in the competent court at its Vienna seat.
