About us

With our headquarters in Rostock, Germany, we have been making it our business for 18 years now to accelerate, optimize and automate even complex process flows in the operation and monitoring of renewable energy plants.

After our two founders and managing directors, Tino Korth and Stephan Thiemann, visited the HUSUM Wind trade fair for the first time in 2003, DrehPunkt GmbH has since grown into a successful medium-sized company.

With rotorsoft we offer a professional, manufacturer-independent software product that is the market-leading application in its field in Germany with a steadily growing international customer base.
