SoundCast

SoundCast provides B2B advertising infrastructure for the digital audio market. It creates value by helping publishers monetise audio inventory programmatically, giving agencies and advertisers access to curated audio supply, and providing ad serving and measurement tools for direct and programmatic campaigns. Its model combines infrastructure software with transaction enablement, allowing it to participate in media flows rather than relying only on pure software licensing.

SoundCast is a French AdTech company operating a proprietary digital audio advertising stack for publishers, agencies and advertisers. Its core products include an audio-focused supply-side platform, an ad server for campaign delivery and tracking, a curated marketplace for premium audio inventory, and an amplification product for branded podcasts. The company is positioned as an independent sell-side platform connecting audio inventory to multiple demand sources worldwide.

The business makes money by enabling audio inventory monetisation and campaign activation. Its customers are primarily audio publishers, podcast networks, streaming radio operators, agencies, ad operations teams and programmatic buyers. Revenue appears to come from a mix of platform usage, transaction take-rates on programmatic spend, ad serving fees, curated marketplace pricing and performance-based billing for podcast amplification.
