SoundCast says advertisers using StackAdapt can now buy its digital-radio, live-stream and podcast advertising inventory directly through the platform, adding another buying route for participating audio publishers.
The partnership was announced November 9. SoundCast’s announcement through industry association Alliance Digitale says the integration is live globally and supports open real-time bidding and negotiated deals. French advertising trade publication Stratégies reported the arrangement November 10.
SoundCast says the offering spans more than 150 publishers. Its named partners include Radio Classique, Radio Meuh, Acast and Audioboom. That total is company-reported; it is not a count of individual radio stations or listeners. The offering also includes in-store and in-game audio.
For Internet radio operators already represented by SoundCast, the practical change is access to buyers using another advertising platform. That creates an additional opportunity to sell available inventory; it does not establish that stations will receive higher rates or fill more advertising slots.
The announcements do not disclose publisher revenue shares, minimum participation requirements or measured revenue gains. Independent stations considering the service still need to establish their eligibility and commercial terms.
The agreement follows other efforts to connect audio inventory with automated buying, including the Triton–RCS broadcast-radio integration. Wider buyer access is the verified development here; its financial benefit to an individual station remains unproven.
