The organisation that meets everyone
BusinessEurope — the confederation of European industry federations — has met 599 unique EU officials across 1,788 disclosed meetings. To put that in context: the European Commission employs roughly 32,000 staff. BusinessEurope has met nearly 2% of them in a formal lobbying capacity.
Google, with the second-widest network, has met 434 officials. Microsoft reaches 327, CEFIC 341, and Amazon 292. These are significant numbers, but BusinessEurope's lead of 165 officials over its nearest competitor is extraordinary — it means they have access to entire layers of the Commission bureaucracy that no tech company reaches.
The consultancy question
Kreab Worldwide — a lobbying consultancy — has met 179 unique officials. Unlike trade associations or corporations, consultancies meet officials on behalf of undisclosed clients. Kreab's 367 total meetings represent access that is effectively invisible: the meetings are disclosed, but the ultimate beneficiary is not.
Shell (172 officials), Airbus (176), and the American Chamber of Commerce (155) round out the top 15. The data is searchable on GovLens: pick any organisation and see exactly which officials they met, when, and about what.
