As a leading critical infrastructure service provider, we live and breathe for small and medium-sized enterprises – as partners on a level playing field. Through flexibility, innovation and resources, we help our SME partners to grow stronger, so together we can create sustainable infrastructures that secure living spaces and pave the way for the mobility and energy transition.
Empowering strong, local SMEs to implement infrastructure solutions that drive forward the mobility and energy transition and prepare our regions for the future. With our concentrated SME expertise, we offer a compelling alternative to large corporations—delivering greater speed, enhanced flexibility, and a truly entrepreneurial mindset.

A challenge turned into a success story
In 2020, Dirk and Ralf Sojka started with an ambitious vision – and transformed a company into a growing force in regionally specialized infrastructure engineering. With AUCTUS Capital Partners AG as a partner, their idea became TERRAS – a dynamic network that leverages synergies, strengthens SMEs and redefines the industry.

TERRAS redefines growth
What began as an ambitious 10-year plan became reality in just three years. Doubled twice in two years – a pace that is second to none. TERRAS has exceeded its targets and continues to build for the future. With the clout of a medium-sized company, a clear mission and a strong network, we are reshaping the market – far removed from corporate structures, but on an equal footing with the big players.
We take a conscientious approach to sustainable action for future-proof infrastructure design: from resource-efficient processes and fair working conditions to responsible corporate management. We integrate ESG (environmental, social and governance) principles into our work – with a clear view to the future.
