Andrew chats with Substack co-founder Hamish McKenzie for a conversation on how Substack became one of the most consequential media platforms of the last decade. They discuss the origins of the company's subscription-first model, why owning your audience relationship is the future, and AI’s role in journalism. Hamish also opens up about what it was like working at Tesla under Elon Musk, how Substack responded when Musk tried to buy the company (and later tried to "nuke" it), and where the platform goes from here (hint: it’s not just a text-based platform).
