Substack
The reader-network-first paid newsletter and podcast platform that defined the modern independent-publisher renaissance.
What Substack is
Substack is a US publishing platform founded in 2017 by Chris Best, Hamish McKenzie, and Jairaj Sethi. The product combines newsletter hosting, paid subscriptions, podcasts, and, critically, a reader-side network (the Substack app + Substack Notes) that helps publications gain subscribers from other publications' readers. Category-defining for the independent-publisher renaissance.
Who uses Substack
Independent writers, journalists, opinion columnists, podcasters, and anyone building a paid-subscriber audience for their own voice. Increasingly used by publications and businesses too, though the platform's identity remains creator-first.
What Substack costs
Free to start. Substack takes 10% of paid-subscription revenue + Stripe processing fees. No monthly SaaS fee. That model appeals to creators launching a paid publication with no upfront cost; it becomes expensive at scale (a $100K/year Substack pays $10K/year to Substack, where Beehiiv's $99/month tier would be ~$1,200/year for the same volume).
Where Substack sits in the growth-vendor context
Substack shows up on shortlists in The Wall's Content Marketing pillar. Buyers who consider Substack typically also evaluate Beehiiv, Mailchimp, ActiveCampaign. The shortlist question is usually not whether Substack is a good product (it generally is, or it wouldn't be on the list), but whether its center of gravity fits the company's shape.
