Cloud-Telefonie für das Büro, zu Hause und unterwegs. | Wir arbeiten agil, lean und crossfunktional.

Founded in 2004, we at sipgate were the first German VoIP provider and have been developing internet and telephony services ever since. We provide hundreds of thousands of customers with innovative landline and mobile services for the home, office, and on the go.

Our foundations were laid in a student dormatory in 1998 with two employees and the rate comparison website “billiger-telefonieren.de”.

Today we have over 140 colleagues and work together on making the lives of individuals and businesses easier with our services in a fantastic office located in the harbor of Düsseldorf. No investors, continuously profitable, and a clear vision forward.
