About us

Our Story

The motor behind all PROEBIZ activities, the owner of the PROEBIZ trademark and the software of the same name is NAR marketing, which was created in 1996 by the transformation of N.A.R., Milan Kaplan’s previous company, which had been operating from the beginning of 1990. We first came across eAuctions in 2000 and gradually we’ve shifted away from other marketing activities and expanded into the digitalisation of all processes in both corporate and public procurement.

The headquarters of NAR and nerve-centre of PROEBIZ are in Ostrava. We also have offices or other forms of representation in Prague, Bratislava and Katowice.

Furthermore, we initiated the formation of the Czech and Slovak Associations for Providers and Users of Digital Procurement Solutions (APUeN CZ and APUeN SK).

For more than fifteen years we have been producing a weekly blog called TOBOGAN, which is a summary of that week’s events.

NAR has a 100% owned subsidiary called Sentinet which serves primarily as an environment for testing and verifying new products.
