Castos

SaaS subscription · Podcast hosting · Founded 2016 · Remote (USA)
👤 Craig Hewitt (Ran a podcast + a $100K/yr editing service first — he knew podcasters' pain and had cash to buy the plugin behind Castos.)🌐 sitecraighewitt.com𝕏LinkedIn

Castos hosts podcasts, but it grew by buying a free WordPress plugin and upselling its users paid hosting.

Will it work? · our read
Bought his funnel. Smart entry, but podcast hosting is a commodity — Spotify and Buzzsprout bundle it, and the plugin only converts a slice. Growth now depends on content, not the one trick.

Revenue is first-party where it counts: Craig Hewitt stated 'just under $1.5M ARR' on Mixergy (2021), and Castos's own press page documents the $120K TinySeed round and the '$10K MRR in 12 months' from the bought plugin. The current about $3.6M ARR (2024) is a Latka third-party estimate, not confirmed — treat it as directional. Not a pure bootstrap: Castos took the TinySeed check (some sources report up to $750K raised total). The 30K+ plugin figure is from WordPress.org. Drama is real and documented — the plugin acquisition is the crux, not a narrative imposed after the fact. We never score you.
