I know several hundred French people in Silicon Valley / SF, and this very bright & accomplished group all say today's French govt and French mentality works against startup success. But needing to grow beyond retargeting immediately is not one of them. A good online marketer spends 20-25% as much on retargeting as he/she does on search, and search is a $30B+ business.

Criteo would advertise weather and hotel sites on their list that belong to their companies and steal your business.
