Castos

What Castos does

Castos is a privately held podcast hosting and distribution platform founded by Craig Hewitt, headquartered in the United States and serving a stated base of more than 40,000 podcasters. The core product provides unlimited episode, show, and download capacity on a flat-rate subscription model starting at $19 per month, with one-click distribution to major listening destinations including Apple Podcasts, Spotify, Amazon Music, YouTube, Stitcher, and Google Podcasts. Its modular product surface extends beyond hosting into audience growth (YouTube republishing, transcription in 19 languages, AI-generated show notes, social posts and chapter markers via the Castos AI Assistant), monetization (Castos Commerce with zero transaction fees, Castos Ads dynamic ad insertion, and Castos Campaigns for back-catalog insertions), and content delivery (private and hybrid podcasting, native iOS and Android apps). A proprietary WordPress plugin, Seriously Simple Podcasting, anchors the platform inside the WordPress CMS workflow, the company's primary distribution and ecosystem channel.\n\nThe business operates a product-led go-to-market with a 14-day free trial, instant self-serve account creation, and a free white-glove migration service for users switching from competing hosts. Pricing is tiered across Essential, Growth, and Pro subscription plans, complemented by transaction-based revenue from Castos Commerce and unit-priced professional services from Castos Productions (audio editing tiers with 72-hour to one-week turnaround). Revenue is also supplemented by an affiliate program offering 25% recurring commission on referral subscriptions for the first 12 months and 10% on production services. Customers span serious individual creators, agencies and networks, coaches and consultants, churches, universities, nonprofits, and enterprises using podcasts for internal communications; named reference customers include WellnessMama, Buffer, CoSchedule, James Altucher, and Ladybug Podcast. Castos has raised disclosed funding of $756,000 from Automattic and Emilia Capital in 2021, with earlier backing from TinySeed in 2019, and is founder-led with no disclosed parent company or institutional majority owner.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Acast: Global podcast hosting and monetization platform with an ad marketplace and self-serve tools for creators. Comparable to Castos on hosting and monetization, with much broader international scale and ad-network demand.
• Simplecast: Spotify-owned podcast hosting and analytics platform serving enterprise and SMB podcasters with distribution, monetization, and embeddable players. Comparable feature footprint to Castos but operating at larger scale under Spotify's umbrella.

Direct peers

• Transistor.fm: Premium podcast hosting platform focused on professional and business podcasters with unlimited shows, private podcasting, distribution, and analytics. Closely aligned with Castos on target customer (serious/business podcasters) and flat-pricing model.
• Buzzsprout: Established independent podcast hosting platform targeting independent and SMB podcasters with subscription plans, distribution, and analytics. Closely comparable to Castos on customer profile, pricing model, and feature scope (unlimited storage, basic monetization).
• RSS.com: Podcast hosting and distribution platform focused on creators and brands, with monetization, analytics, and unlimited hosting — overlapping Castos on subscription hosting, monetization, and analytics.
• Podbean: Podcast hosting platform offering unlimited hosting, distribution, monetization (Podbean Ads), private podcasting, and a mobile app — a near-direct feature comparison to Castos, with similar pricing for SMB podcasters.
• Libsyn: One of the oldest podcast hosting platforms offering unlimited hosting, distribution to major directories, monetization (ads, subscriptions), and analytics. Most directly comparable to Castos in core hosting, distribution, and monetization features across SMB and pro podcaster tiers.
• Blubrry (PowerPress): Podcast hosting and WordPress plugin (PowerPress) provider targeting WordPress-based creators and SMB podcasters. Highly comparable to Castos in the WordPress integration lane in particular.

Emerging players

• Hello Audio: Specialized private podcasting platform for membership sites, courses, and communities. A direct comparator to Castos's private and hybrid podcasting pillar — focused on the same creator-coach/educator and membership use case.

Others

• Squadcast: Cloud-based remote recording platform for podcasts (and video) that is also a Castos integration partner. Adjacent-enabling rather than directly competing, but the remote-recording category increasingly overlaps with end-to-end podcast production workflows Castos Productions targets.
