Chris Best of Substack on the Future of Media
The a16z Show2 September 2025·46 minutes
What if the future of media isn’t controlled by algorithms or legacy institutions—but by independent voices building directly with their audiences?
In this episode, Erik Torenberg is joined by Chris Best, cofounder and CEO of Substack, along with a16z general partners Katherine Boyle and Andrew Chen.
We trace the origin story of Substack and its cultural impact, including how it reinvented the business model for independent media. We also explore the evolution of blogging, the rebundling of media, and what the future holds as attention becomes the scarcest resource.
