In 2018, the sample monitored by OpenCorporation went from 200 to over 2300 companies. In the meantime the research group has equipped itself with new tools and data sources.

As a consequence of this commitment and in order to improve the quality of the Rating, in the last year our researchers have continuously refined the research methodology and the algorithms on the basis of which the indicators and the final rating of each company are calculated..

A series of documents will shortly be published on this page describing the work, still in progress, and the methodology adopted.
