AdTonos

AdTonos is a UK-based private AdTech company focused on programmatic audio advertising. It operates a unified marketplace that combines demand-side and supply-side capabilities for digital audio, helping advertisers and agencies buy inventory across radio streams, podcasts, apps and gaming environments, while enabling publishers and broadcasters to monetise audio inventory through insertion, replacement and programmatic access. The company makes money primarily from media spend flowing through its audio marketplace, likely via take rates or margin between advertiser spend and publisher payouts, and also positions parts of its stack as SaaS for both buyers and sellers. Its product set extends beyond core trading into audio measurement and attribution, server-side insertion infrastructure, interactive voice ads, audio creative enhancement and in-game audio monetisation. Direct customers are advertisers, agencies, broadcasters, streaming providers, podcast networks and gaming publishers rather than end consumers.
