MediaSquare

The company operates a two-sided advertising marketplace that connects French media publishers with advertisers and agencies through programmatic pipes and a proprietary self-service interface. On the supply side, it onboards premium publishers and aggregates their digital display and video inventory across desktop, mobile and CTV environments. On the demand side, it enables programmatic access via standard integrations and curated deal IDs, as well as a UI where advertisers can configure and run campaigns.

Value is created by giving publishers a collective sales channel that aims to enhance yield and maintain control over their inventory, while providing buyers with consolidated access to brand-safe, French media inventory through a single marketplace. Commercially, the firm sits in the transaction flow between buyer and publisher, taking a cut of the media budget and offering optional managed sales and campaign support.

MediaSquare is a France-based digital advertising marketplace owned by major French media groups. It aggregates premium French publisher inventory (hundreds of sites and apps) and sells it programmatically to media buyers, agencies and advertisers via marketplace connections and a self-service buying interface. The company positions itself as a publisher-controlled alternative to global ad exchanges with an emphasis on brand safety and curated inventory.

It generates revenue by facilitating programmatic deals and insertion orders across its publisher network and by operating a self-service buying product for smaller advertisers. Its customers are both supply-side partners (publishers contributing inventory) and demand-side buyers (agencies, trading desks and advertisers) who pay for media on a CPC/CPM basis, with MediaSquare earning commissions and related fees on spend flowing through the platform.
