Havas buys advertising on behalf of its clients, through the accounts and relationships it already holds. Briefing an agency means telling them the outcome and the budget rather than picking the ad spots yourself — useful when a buy spans more sellers than you want to manage, or when the doors you need are closed to a buyer with no seat. This directory records that the company exists and what it says it does; it takes no commission and makes no recommendation.
