Wemass

The company operates a consortium-based digital advertising marketplace that aggregates premium inventory from leading Spanish publishers into a unified platform. On the demand side, advertisers, media agencies and trading desks gain single-point access to multiple formats (display, video, high‑impact, audio) and audience segments across the participating publisher network. On the supply side, member publishers centralise the sale of part of their digital inventory and audiences through this marketplace, gaining broader demand and coordinated pricing and packaging.

Value is created by simplifying access to fragmented publisher inventory, standardising products and formats, and layering first‑party audience data collected via a proprietary DMP deployed across the consortium sites. An internal creative unit provides production and optimisation of bespoke and high‑impact formats, improving campaign performance and enabling publishers to sell richer products. The platform positions itself as a premium, brand‑safe environment relative to open exchanges, increasing yield potential for publishers and planning efficiency for buyers.

Wemass Media Audience Safe Solution is a Spanish digital advertising marketplace created by major publishing groups Godó, Prisa and Vocento. It aggregates premium inventory and audiences from consortium publishers and provides a single access point for buyers across programmatic and direct channels in Spain.

The company operates as a sell-side marketplace with its own data management platform integrated across member sites, offering display, video, high‑impact formats, and a premium digital audio marketplace. Its customers are advertisers, media agencies and trading desks that buy media on a CPM basis, as well as consortium publishers that use the platform to monetise their inventory; Wemass earns revenue from media transactions, premium format uplifts and associated creative services provided by its in‑house creative team.
