bringing
you all
under
one roof
It all started in 2010, when the company was created as a freelance organization – sole trader. Back then the company was working on consulting and technical support, injection molding and mold manufacture projects.
In 2016 company expanded its borders with sprawl of our production program of plastic products. At the end of the 2016 company added a 3D metal printer (EOS M280) to the facility and in 2017 a 3D metal print program to our services, which was a huge milestone as we became the only provider of this kind of service in Slovenia and the west part of ex-Yugoslavia territory. In 2019 our business extended even further, as we added a brand-new facility to our business and are now operating on more than 3000 square meters of production. With every year stepping further to our goals, the number of employees had grown, as we increased the rate for 1700% in 4 years. Stepping into the 2020 the company has transferred itself from “s.p.” (sole trader) to a “d.o.o.” (limited liability company) and renamed to MARSi Group d.o.o., becoming fully competitive organization on all aspects of our business performance.
Nowadays company is focusing on developing its services to the fullest potential, creating healthy and friendly working environment for our workers and expanding even further to our long-term goals.
