Stiegeler Internet Service GmbH
Stiegeler Internet Service GmbH ("SIS") has been building, leasing and operating fibre optic communication networks and providing value-added services for private and business customers since 2008. The company develops areas that previously had no broadband connection ("white spots") with the aim of providing comprehensive high speed Internet connection based on the latest fibre optic technology.
Since the end of 2018, Adiuva has been supporting SIS in the further expansion of its fibre optic infrastructure and the extension of its telecommunications business. In 2019, for example, HochRheinnet GmbH was acquired as part of a corporate succession initiative.
Today, SIS supplies over 15,000 households and companies in the southwest of Baden-Württemberg with fast internet, telecommunications and value-added services. With a broad network of experts and additional growth capital, Adiuva supports SIS in taking advantage of the opportunities in the fibre optic broadband market.
