About Castos

Castos was formed in 2017 around the Seriously Simple Podcasting plugin, a popular way of self-hosting podcasts. Castos added analytics, hosting, and an embeddable media player, and now provides automated transcription, a simple website, and allows content to be republished to YouTube.

On top of this, the company also provides podcast editing services.

About Transistor

Founded in 2018, Transistor is a relative newcomer to the hosting space, and has since leant its services to some big names including VH-1, Basecamp, and Kickstarter.

Although not as full-featured as others, lacking an adequate podcast website or IAB-compliant metrics, for professionals looking for affordable hosting for a podcast whose website is handled elsewhere – or where the podcast forms part of a larger offering – Transistor is easy-to-use and lightning-fast to launch with.

The service was born out of one of the founders’ work projects, so it carries the DNA of a service meant for companies that are using a podcast as part of a wider media strategy. In that respect, it’s not a good fit for hobbyists and beginners, but its no-nonsense interface makes it a good pick for busy show runners.

The Podcode podcast, the audio version of the Podcode.tv channel, is hosted with Transistor.
