Substack is building a new economic engine for culture, giving the brightest, most interesting, and most creative people on the internet the power of their own publishing platform. The terms of our culture should not be set by gate-keeping legacy media or chaos-fueling social media, but by the people who make and participate in that culture. Substack's model, based on direct subscriptions, has fueled an explosion of independent publishing. It empowers creators with economic autonomy, creative ownership, and a direct connection to their most engaged audiences.

What We Do
Substack lets writers connect with their audience on their own terms and earn money doing it. We make it simple for writers to publish to an email list that they own, get discovered on the web, and charge for subscriptions.
More than 500,000 people pay to subscribe to writers across the Substack network, and the top writers make millions of dollars a year. Substack’s model depends on the success of writers using Substack – we only make money when they do.
