Soundcast operates an independent sell-side platform (SSP) for digital audio advertising, connecting publishers and advertisers across the global audio ecosystem. Its technology stack, developed in-house since 2018, includes an SSP, an ad server, and a curation marketplace covering podcasts, streaming radio, in-game audio, in-video audio, and in-store audio across the Americas, EMEA, and APAC.

For publishers, Soundcast provides a dashboard to track advertising revenue, impressions, fill rate, and completion rate, with granular reporting by network, podcast, streaming radio, placement, geolocation, and device. Publishers can set up programmatic deals and manage campaigns and creatives in real time, supported by dedicated business development, technical teams, and round-the-clock troubleshooting.

For advertisers, Soundcast offers access to over 100,000 podcasts across more than 20 countries and over 2,000 live and web radio stations, along with in-game, in-video, and in-store audio placements, and brand podcast amplification with embedded players. The company reports processing over 2.2 billion ad calls per month in Europe and 1.5 billion in North America. It is led by co-founders Patrice Sguerzi (CEO) and Jean-Baptiste Quenum (COO), maintains offices in the EU and US including a London office, and has formed partnerships such as with NumberEight, Basis Technologies, and The Trade Desk.
