SunMedia

SunMedia operates a two-sided adtech model. On the supply side, it partners with publishers and media owners to monetise inventory through programmatic tools, ad serving infrastructure and premium formats. On the demand side, it sells access to that inventory and related targeting, creative and campaign delivery capabilities to advertisers and agencies. Value is created by aggregating premium media supply, packaging it into scalable campaigns, and improving yield and attention outcomes through proprietary technology.

SunMedia is a Spain-headquartered adtech business operating an advertising network and related publisher monetisation infrastructure. It aggregates inventory from premium publishers and sells digital advertising solutions to brands and agencies across video, native and performance formats, while also offering proprietary technology including an SSP, header bidding capabilities, a video player and custom ad formats.

The company makes money through advertiser media spend, transaction margins between buyers and publishers, and technology-linked monetisation around programmatic yield and premium creative formats. Its customers are businesses rather than consumers: advertisers, agencies, publishers and media owners. Evidence also shows SunMedia was acquired by Magnum Capital in 2022 and later integrated with Rich Audience and AdPone under the EXTE grouping, suggesting SunMedia now functions as part of a broader consolidated adtech platform.
