The concentration
That density sits inside the same city as the European Commission, Parliament and Council, giving Brussels-based firms direct proximity to EU digital-policy and research-funding programmes that firms elsewhere have to travel for.
What that means locally
A genuinely bilingual, internationally staffed market — Brussels runs in French and Dutch simultaneously, with English widely used in the EU-institutional and corporate layer, which is unusual even by Belgian standards.
The local business economy split reflects the city's dual identity: an EU-policy and corporate-headquarters layer that procures formally and internationally, and neighbourhood-level Brussels business that is more traditionally Belgian — cautious, relationship-driven, unhurried.
The buyer
Formal and multilingual in the EU-adjacent layer; more conventional and price-conscious in the neighbourhood economy. Assume nothing about which language a Brussels business prefers without checking — the city genuinely runs on both.
The practical read
Offer French and Dutch, not just one. If you're targeting the EU-adjacent layer specifically, English and a formal register work; if you're targeting neighbourhood Brussels, treat it like any other careful, relationship-first Belgian city.

Caveats and sourcing
- Verifiable — the ICT company count, employment share and startup-founding share, as reported by the Brussels regional economic development agency.
- Characterising claims — the description of the bilingual market split and buyer behaviour is interpretation.
