Mumbler

Mumbler was a subscription-based podcast platform that operated from April 2021 until September 30, 2025. The company was founded with the vision that subscription podcasts could provide creators with a solid monetization pathway for their content.

The platform offered podcast hosting services and RSS feed management, allowing creators to publish both free and subscriber-only content. Mumbler provided features including AI transcriptions, audio insertions, marketing tools like coupons, annual subscription plans, and customizable podcast landing pages. Creators could set up multiple podcasts and audio series within a single account while maintaining both public and private feeds.

Mumbler also published "Inside Podcasting," a weekly newsletter on LinkedIn that provided podcasting news, resources, and tips to help creators improve their shows. The company ceased operations after being unable to achieve the necessary profitability despite exploring various monetization approaches over its four-year run.
