Overview

Substack was founded in 2017 with headquarters in San Francisco, United States. It is a newsletter and content publishing platform in the automation space, co-founded by Chris Best, Hamish McKenzie, and Jairaj Sethi. It lets writers publish, distribute, and monetize content without building their own website or email system.

Substack's core idea is "sustainable business models for independent writing." The platform provides a writing editor, paid subscription paywalls, email distribution, and social features. Creators can publish for free or set monthly/yearly paid tiers, with the platform taking only a 10% cut while creators keep 90%. As of 2026, Substack supports 1M+ paid subscriptions and hosts thousands of journalists, analysts, and independent creators, making it key infrastructure for content marketing and the creator economy.

Key Strengths

  • All-in-One Monetization: Writing, distribution, paywalls, and social features (4 core capabilities) in 1 platform, with 0 technical barrier to paid subscriptions.

  • Creator-Friendly Revenue Share: Only a 10% platform cut, keeping 90% for creators - better than most platforms' 20%-30% fees.

  • Owned Subscriber Data: Paid and free subscriber data belongs to creators and can be exported with 1 click; see subscriber management.

  • Built-In Discovery & Social: Notes feed, recommendation network, and Chat (3 discovery tools) help new readers discover content, lowering cold-start costs.

  • Multi-Format Distribution: Newsletter, video, podcast, and comments from 1 dashboard.
