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.
