AdvertiseCast

Leading podcast advertising marketplace with a large self-serve network connecting advertisers to independent and mid-tier podcasters

AdvertiseCast is a specialized podcast advertising platform that serves as a centralized marketplace connecting brands and advertisers with podcast creators. The platform enables advertisers to discover, book, and manage podcast ad campaigns at scale, while giving podcasters tools to monetize their content through host-read and dynamically inserted advertisements. With a network spanning thousands of podcasts across diverse genres and audience demographics, AdvertiseCast simplifies what has traditionally been a fragmented, relationship-driven buying process. The company offers a self-serve interface for advertisers to browse podcast inventory, filter by audience size, category, and CPM rates, and execute campaigns with measurable outcomes. For podcast creators, AdvertiseCast provides monetization infrastructure including ad management, payment processing, and audience analytics. This dual-sided marketplace model creates network effects that benefit both supply and demand sides of the podcast advertising ecosystem. AdvertiseCast was acquired by Libsyn (Liberated Syndication), one of the oldest and largest podcast hosting and distribution companies, in 2020. This acquisition positioned Libsyn to offer an end-to-end solution combining podcast hosting with advertising monetization. The combined offering strengthened Libsyn's competitive standing against rivals like Spotify's Anchor, iHeartMedia, and other podcast monetization platforms, making AdvertiseCast a key component of Libsyn's revenue strategy.
