CueWhat are the podcast advertising platforms?
Thirteen sellers matter for a first test: four self-serve platforms (Spotify, Acast, AudioGo, Buzzsprout), three marketplaces (Libsyn Ads, Podcorn, Gumball), two managed routes (Amazon DSP, SiriusXM Media), and four agencies. Only Spotify publishes a hard minimum: 250.00. Ten of the thirteen publish no figures at all.
Each lane below is one seller. The chip shows the published minimum where one exists. Where the seller publishes nothing, the lane says so; this site does not fill silence with estimates. Cross-check entry costs on the minimum spend table, then move to Stage 3: rates.
