The Substack Playbook: Inside The $650M Platform Rewriting Media, Trust, and Creator Economics | Chris Best & Hamish McKenzie (Co-Founders)

1 hour 25 minutes

In a world where attention is fragmented and algorithms rule the content landscape, Chris Best and Hamish McKenzie are taking a radically different approach with Substack. Rather than chasing clicks, Substack focuses on a simple yet powerful idea: creators should own their work and make money directly from their audience through paid subscriptions. With over 5 million paid subscriptions and tens of millions of active readers, Substack has turned this model into a transformative force in media.

In this episode, Chris and Hamish unpack how they’re reshaping creator economics, navigating AI’s role in creativity, and enabling a new era for writers, from serialized fiction to short-form video. Their bet? That if content adds real value—whether it educates, entertains, or helps people earn—audiences will pay for it.

In our conversation, we explore:

• How Substack grew from a simple newsletter tool to a multi-format media platform with 5 million+ paid subscriptions

• Why the "soul connection" between creators and audiences is becoming more valuable in an AI-dominated world

• The inside story of Substack's clash with Elon Musk and how it ultimately strengthened their platform

• Why the ceiling for great writing and culture might be much higher than we're currently imagining

• How Substack's subscription model creates dramatically better economics for creators than ad-supported platforms

• Chris's "grand unified theory" for how AI will influence content creation and consumption

• Why their short-form content isn't just a "sticky trick" but a pathway to deeper engagement and discovery

• The future of traditional prestige media brands

• Much more
