What 366 does
366 creates value by bundling advertising inventory from multiple regional media owners into a single commercial marketplace. Instead of each publisher selling independently, 366 centralises sales, packaging, planning and execution across print, digital, video and local TV. This reduces fragmentation for buyers and improves monetisation efficiency for participating media owners. Its business model depends on audience aggregation, local targeting products and cross-channel packaging that make regional media easier to buy at scale.
Category differentiation
366 is not a DSP, SSP or standalone adtech software vendor. It is primarily a French media sales house commercialising aggregated regional media inventory, with some publisher activity through Diverto.
Strategic context
AI-supported assessment from the existing company research; distinguish interpretation from sourced facts.
366 is a French media sales house that commercialises advertising inventory on behalf of regional media owners. Its core business is to aggregate fragmented supply across 55 regional daily newspapers, associated websites and mobile apps, local television channels, and selected owned or operated media properties such as Diverto, then sell that access to advertisers and media agencies through unified national, local and title-specific offers. The company makes money by selling ad placements and campaign packages across print, web, mobile, video and linear TV. Its customers are advertisers, brands, local businesses and agencies that want either broad reach across France or precise local activation by department, publication title or store catchment area. The commercial proposition is based on simplifying buying across multiple regional publishers through one sales interface.
Company news briefing
Briefing updated:
366 has strengthened its market position through the adoption of its Claire_ platform by Auchan and Havas Media France, highlighting the sales house’s focus on data-driven regional targeting. Strategic engagement with major agency groups continues, evidenced by leadership participation in WPP Media’s recent industry briefings. Additionally, the company remains a primary partner for large-scale public sector campaigns, recently executing a nationwide health awareness initiative for Santé publique France across its extensive local media network.
Business model & monetisation
Revenue comes primarily from selling advertising inventory and packaged media campaigns across aggregated regional press, digital and local TV properties. Commercial mechanisms likely include print insertion fees, digital CPM-based pricing, video pricing, TV spot pricing and bundled cross-channel packages such as national reach products, department-level targeting and drive-to-store solutions. The company monetises both broad reach packages and premium targeted offerings that command higher value because they simplify fragmented regional media buying.
