Criteo
Paris-headquartered commerce-media and retargeting platform. A large, publicly traded European adtech alternative to the Google and Meta ad duopoly.
Quick facts
A real scale alternative to the Google and Meta ad duopoly, operating under EU/GDPR rules with its own infrastructure.
It's still a retargeting and ad-tracking business at its core, so switching to it doesn't reduce ad-tracking exposure the way avoiding adtech entirely would.
Why does it score 83?
Incorporated in Paris, France – a full EU member state.
Publicly traded but headquartered and controlled from France, keeping the company anchored in the EU rather than under a foreign parent.
Criteo runs its own global data-centre infrastructure, including servers in France and Germany.
GDPR-compliant, but the platform isn't open source and there's no independently published security audit on record.
