What SoundCast does
Soundcast is an independent, French-headquartered sell-side platform (SSP) founded in 2018 that specializes in programmatic digital audio advertising. It operates a proprietary adserver, curation marketplace, and demand-agnostic monetization stack that connects 800+ audio publishers, including podcasts, streaming radio, in-game audio, and in-store audio, to more than 20 demand-side platform (DSP) partners. The company processes over 3.7 billion ad calls per month and is positioned as an audio-first alternative to general-purpose omnichannel SSPs.
Its core technology combines a sell-side platform with a curation layer that programmatically packages audio inventory into deals optimized for buyer KPIs. The platform supports differentiated formats across emerging channels, including in-store audio (e.g., Boulanger retail deployments) and gaming audio (via Audiomob and Odeeo partnerships), as well as privacy-first podcast targeting through a partnership with NumberEight. AI and machine learning are applied to bid optimization, brand safety anomaly detection, content curation, and creative generation.
Soundcast makes money as a marketplace intermediary, earning take-rates and commissions on the audio advertising volume transacted through its platform. Its go-to-market targets three segments: publishers seeking incremental audio demand, agencies executing omnichannel buys (integrated with workflow partners such as Basis Technologies), and brand advertisers. The company employs 25-27 people, of which approximately 60% are engineers, and operates from headquarters in France with commercial offices in London (opened November 2025) and the United States (launched December 2024). Platform-level metrics indicate revenue per day of €32.2K, up 12.6% year-over-year, with fill rate growth of 2.1% and eCPM growth of 8.4%.

SoundCast competitors and assessment
Company assessmentDirect peers
- Audioboom: Podcast hosting and ad-tech company that monetizes content through programmatic audio advertising — a Soundcast customer whose own monetization stack competes in the same podcast SSP space.
- Acast: Global podcast hosting and monetization platform that both supplies inventory into Soundcast's SSP and operates its own programmatic marketplace — a key Soundcast customer that is also a competitor in podcast ad-tech.
- Triton Digital: Long-established audio SSP and ad-tech platform owned by SiriusXM, serving podcasters, streamers, and broadcasters with programmatic audio ad serving, measurement, and demand facilitation — the closest direct competitor to Soundcast's SSP and ad-server stack.
- AdsWizz: Audio ad-tech platform acquired by SiriusXM (parent of Triton Digital) providing programmatic audio advertising, dynamic ad insertion, and podcast monetization technology — directly competing with Soundcast's SSP, ad-server, and podcast monetization offerings.
