Podcorn

Self-serve podcast advertising marketplace focused on the long tail of independent and mid-tier podcast creators, operating as part of the SiriusXM audio ecosystem

Podcorn is a technology-driven podcast advertising marketplace that democratizes access to podcast sponsorships by enabling direct connections between brands and podcast creators of all sizes. Founded in 2019 and headquartered in Los Angeles, the platform allows advertisers to discover podcasts, manage campaigns, and execute host-read advertisements without requiring large minimum spends, opening up podcast advertising to SMBs and mid-market brands that were previously priced out of the channel. The platform's self-serve model automates much of the workflow traditionally handled by agencies or podcast networks, including creator discovery, proposal management, content approval, and payment processing. Podcorn was acquired by SiriusXM/Pandora in 2021, giving it access to a broader ecosystem of audio advertising tools and inventory while continuing to operate as a distinct marketplace platform. The acquisition positioned Podcorn within SiriusXM's growing podcast and streaming audio portfolio, complementing properties like Stitcher and the SiriusXM Podcast Network. Podcorn's marketplace model emphasizes host-read, native advertising formats which consistently outperform dynamically inserted ads in listener engagement and brand recall metrics. In the competitive podcast advertising landscape, Podcorn differentiates itself by focusing on the long tail of podcasting — the vast number of independent and mid-tier creators who collectively reach enormous audiences but are underserved by traditional podcast ad networks. This approach gives advertisers access to highly engaged niche audiences while giving creators of all sizes a viable monetization path, making Podcorn a significant enabler of the broader podcast economy.
