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.

Pinecast began life in 2015, and its original code was made available to read and fork on Github. It was created by Matt Basta, a software engineer who would go on to work at Stripe Connect, which gave Pinecast an advantage in making it easy for podcasters to collect donations from listeners.

The service offers a flexible and highly-customisable podcast website, options to solicit feedback from listeners, exportable metrics including Spotify data, and easy submission to popular directories.
