Pick 2 to 6. This ranking as CSV All companies in the analysis workbench

The CSV holds the rows shown with place, sector, figure and financial year. The analysis workbench shows the same place and sector, sorted by this figure, with every registered company. Companies without recent accounts, which this ranking leaves out, are included too.

9,059 more companies with this figure are not in the top. Every company has its own dossier with all its figures.

Method and sources

Start date in the KBO register, for companies and associations that are still active and file recent accounts. Those the register starts on 1 January 1968 are left out: there that date stands in for an unknown, often earlier founding.
