Supporting Cast is a podcast membership and subscription platform originally built by Slate to power its Slate Plus membership program, and now part of Graham Holdings. It enables podcasters \u2014 from independent creators to large networks like NPR and SiriusXM \u2014 to sell and deliver premium content including bonus episodes, ad-free feeds, audiobooks, newsletters, and multi-show bundles, all accessible inside listeners’ existing podcast apps such as Apple Podcasts and Spotify without requiring a new app download.<\/p>\n
The platform is designed to minimise friction for both podcasters and listeners. Subscribers can sign up in two taps using Apple Pay or Google Pay, with no passwords to remember and no RSS feed copying required. Supporting Cast also provides branded landing pages, targeted personalised audio messaging (such as welcome notes and expiring credit card warnings), premium feed protection against sharing, and detailed analytics on subscriber growth, revenue, and per-member listening behaviour.<\/p>\n
Beyond public podcast subscriptions, Supporting Cast also serves enterprise clients with secure internal podcast delivery, including SSO integration and per-employee listening analytics. The platform takes approximately 10% of annual subscription revenue, which reviewers note is more favourable than Apple Podcasts Subscriptions’ 30% first-year cut. Pricing is custom and contact-based, tailored to the size and needs of each show or network.<\/p>\n","protected":false},"excerpt":{"rendered":"
