About us
InSumma s.r.o. has been operating in Slovakia and the Czech Republic since 2007. It is formed by a group of major German companies, which decided to expand their activities in the region of eastern Central Europe under one umbrella on the basis of the established trend of development of their activities, cooperation and a constantly growing number of satisfied customers.

Wide portfolio of brands
The products and services offered by these companies under our umbrella do not compete with each other, on the contrary, they complement each other and thus maintain their own identity, brand and integrity.
Our commitment
The name of the company, which in Latin means “At the top“, gives us a commitment to the fact that all our activities are carried out with one goal in mind, which we always strive to meet, and that is the satisfaction of our business partners and customers.
