Substack — Net Worth and Career Earnings
Substack is a newsletter platform with estimated annual recurring revenue of approximately $25 million, operating on a simple model: it takes 10% of subscription revenue paid to writers on the platform. The business has grown significantly — over 35 million paid subscriptions exist across the platform, generating over $300 million in annual subscription revenue for writers — but Substack's own revenue is constrained by its decision to offer the platform free to use and take only a percentage cut, meaning its revenue is a fraction of the economic value flowing through it.
The platform's top writers illustrate the scale of the opportunity. Publications like The Free Press, Platformer and Lenny's Newsletter generate millions of dollars annually for their writers, and Substack claims a growing number of writers earn over $1 million per year. This success has made Substack the dominant brand in the independent newsletter space, but has also attracted well-funded competition from Beehiiv (which offers a lower take rate) and Ghost (which offers full ownership of the audience). The 10% take rate is increasingly under pressure as writers grow their audiences and gain leverage.
Founded in 2017 by Chris Best, Hamish McKenzie and Jairaj Sethi, Substack raised $65 million in a 2021 Series B at a $650 million valuation. A planned $75 million Series C in 2022 was downsized to $25 million as the fundraising environment deteriorated. The company's positioning as a platform for independent journalism and intellectual discourse — attracting writers who left traditional media — has given it cultural significance beyond its financial scale.
