What kind of data zIndex employs?

zIndex rating uses several data sources to construct the most authentic public procurement database. It is based for the most part on these public sources:

  1. buyer profiles
  2. political parties donations database at PolitickeFinance.cz

Data is retrieved using a proprietary software tool, developed in cooperation with our affiliated company Datlab s.r.o., with the only exception of annual reports data, which is provided by CRIF - Czech Credit Bureau, a.s.

Each dataset is then handled as needed for the purposes of the calculation. The public procurement data in particular is subjected to an extensive cleansing and inspection process, resulting in significantly higher data reliability than that of the official Public Procurement Journal.

Both the data and subsequent analyses are available to the media (via the affiliated Datlab company) mostly free of charge under under these conditions.
