Open-Xchange

🇪🇺 European

German vendor of the OX App Suite mail and office platform.

Open-Xchange AG was founded in 2005 and is registered in Cologne as a German public company with a supervisory board, HRB 95366. There is no US entity above it.

It sells OX App Suite — webmail, calendar, contacts, Drive and the OX Documents editors — to telcos, ISPs, hosting providers and public bodies, who run it under their own brand. The group also owns Dovecot Pro, the commercial edition of the Dovecot IMAP server, and PowerDNS.

Because OX sells to providers rather than to end users, a reader buys the suite from one of them. mailbox.org, run by Heinlein Hosting GmbH in Berlin under German law, is the German retail route: EUR 4 per user per month, a 30-day trial and self-serve signup.
