Topics

The articles on databazakontaktov.sk revolve around one question: how do you work with data about businesses lawfully and practically? They describe where company data comes from, how to check it and where the legal limits of outreach lie.

The principle: give figures with a date and source, say openly what is not known, and do not round in our own favour. The way we work is described on the data sources and methodology page, the current scope on the database status page.
