Ghost — Net Worth and Career Earnings
Ghost is an open-source publishing platform with estimated annual recurring revenue of approximately $10 million, structured as a non-profit foundation that reinvests all profits into the product. Founded in 2013 by John O'Nolan after a viral Kickstarter campaign raised $317,000, Ghost was built as a focused alternative to WordPress — doing one thing (publishing) exceptionally well, without the complexity and plugin ecosystem that makes WordPress difficult to maintain.
The platform operates on two models: a self-hosted open-source version (free, with the creator hosting their own server) and Ghost Pro (managed hosting with a flat subscription fee). Both models take 0% of creator revenue — the defining advantage over Substack. Over 100,000 active sites run on Ghost, including publications from Automattic, Mozilla and thousands of independent creators and media organisations. The open-source nature means creators own their data completely and can migrate their audience elsewhere at any time — an increasingly important consideration as platform risk becomes a concern for professional publishers.
Ghost's non-profit structure is unusual in the SaaS industry — it means the company cannot be acquired or pressured by investors to increase take rates, and all revenue is reinvested in product development. This structure has made it the trusted choice for creators who want permanence and creator-alignment. While Ghost's ARR is modest relative to Substack or Beehiiv, its 50,000 GitHub stars and active developer community give it significant cultural influence in the creator tools ecosystem.
