About us

We are a technology startup founded in 2013 by a trio of founders around the entrepreneur Thoralf Nehls and are based at the Alter Holzhafen in Wismar with a direct view of the Wismar Baltic Sea Bay. You can find our team there and in the branch office in Hamburg’s Speicherstadt.

Our technical know-how, personal experience from corporations and abroad, existing cooperations with universities and the successful start-ups of previous companies contribute to paving the way to a sustainable future – both for us as SonoBeacon GmbH and for our customers.

Our mission: revolutionary solutions for the extended use of smartphones!


Our locations are directly at the port of Wismar and in the Hamburg Speicherstadt.
