Leadership History
3 leaders · 2017 to present
Substack, Inc. is the undisputed cultural vanguard, category-defining market leader, and foundational platform of modern independent journalism, direct-to-reader subscription publishing, and sovereign intellectual discourse. Founded in San Francisco in 2017 by tech entrepreneurs Chris Best (former co-founder and CTO of Kik), Hamish McKenzie, and systems software architect Jairaj Sethi, Substack was created to dismantle the toxic advertising business model that destroyed digital journalism. By building an elegant markdown CMS, email dispatch engine, direct Stripe subscription billing with zero platform lock-in, and the viral Substack Recommendation Graph, Substack catalyzed a historic media exodus. Today, Substack generates over $40 million in annual recurring revenue ($40M+ ARR) via its 10% platform fee on over $300 million in annual gross subscription volume, powering over 3 million active paid subscriptions across elite writers (Bari Weiss, Matt Taibbi, Heather Cox Richardson) under CEO Chris Best.
Substack operates an exceptionally pure, creator-aligned platform revenue-share business model characterized by software gross margins exceeding 80% and complete structural alignment with editorial excellence. Its commercial revenue engine spans two core pillars: First, a flat 10% platform revenue share captured on all recurring monthly and annual paid subscriptions generated by authors (writers retain 90%, minus standard Stripe payment processing fees). If an author publishes for free, Substack is 100% free with zero fees. Second, a one-time $50 custom domain setup fee charged to publications connecting branded web domains. Substack operates zero advertising networks, displays zero banner ads, and never sells or monetizes reader data, maintaining absolute structural alignment with editorial independence and reader trust.

Substack operates at the intersection of media, politics, and technology, navigating complex content moderation and platform dynamics. Key challenges include defending against flat-fee newsletter competitors (like Beehiiv and Ghost) that target high-earning superstar writers with lower software costs, maintaining author content neutrality amidst contentious cultural debates, countering major social platforms (Meta, Twitter/X) that suppress external Substack article links in their algorithmic feeds, managing credit card churn on recurring reader subscriptions, and expanding from written newsletters into scalable multimedia video and podcast formats.
Chris Best currently leads Substack Inc., overseeing strategic vision, balance sheet health, and organizational execution in Independent Publishing Platform, Creator Subscription Newsletters & Digital Media Network.
Under executive direction, Substack Inc. is prioritizing workflow automation alongside disciplined capital allocation to maximize shareholder value.
