Substack launched in 2017 betting readers would pay for newsletters instead of ads

Substack launched publicly on October 16, 2017, with a single flagship publication: Sinocism, the China newsletter by MarketWatch co-founder Bill Bishop, priced at $11 a month or $118 a year. Co-founder and CEO Chris Best, previously CTO of Kik, called the approach "diametrically opposed to the broader Internet news model" — no chasing clicks and eyeballs, just subscriptions from a niche audience.

The product bet was that tooling, not writing, was the barrier. Instead of stitching together MailChimp, WordPress, Stripe and Memberful, writers got one stack for publishing, email, payments and paywalls. Substack took only a small percentage of subscription revenue, so its incentive aligned with writers' income — the more a writer earned, the more the platform earned.

The first proof came fast: Bishop's first day of paid signups added up to six figures in annual revenue. His model was "shamelessly copied" from Ben Thompson's Stratechery — free posts to keep a big audience, paid access to the daily newsletter — and his existing 30,000 free subscribers gave the paid list a warm start.

A year in, more than 25,000 people were paying for Substack newsletters, up from 11,000 in July 2018, reaching 150,000 paying readers. Writers like Judd Legum quit staff jobs to run their own paid newsletters, and the bet — that readers would pay creators directly — had become a template for the media industry.
