StoryWe founded Wemass in Madrid in 2019 with a simple conviction: access to Spain’s best digital media should be straightforward and collective. From day one we set out to bring together the main Spanish digital media groups into a single advertising marketplace — not to replace relationships, but to make them easier to manage. We see ourselves as connectors: smoothing negotiation, reducing friction and helping media owners and advertisers find the right match faster. Every day we work closely with publishers and buyers to keep the marketplace practical, trustworthy and focused on real reach across Spain. Our pride comes from helping local digital media compete more effectively and giving advertisers a clear path to premium Spanish inventory.
