Grow your podcast by placing your episode directly in established podcast feeds.
Your episode appears as a native "You Might Also Like" recommendation inside established podcasts' feeds, reaching active app listeners instead of web traffic.
The platform hosts of shows that accept a drop must preview and approve it, giving both sides control over what enters their audience.
Only Apple Podcasts and Spotify and other verified apps are served, with bot farms and web players blocked for IAB-compliant metrics.
You set your CPM and budget, with most bids between $50 and $250 CPM and a $500 minimum. You only pay for delivered downloads and can stop a campaign at any time.
