Episode summary
Substack Cofounder on AI Slop Content & the Decline of Social Media
The a16z Show
· · Hosts: Erik Torenberg · Guests: Chris Best, Katherine Boyle, Andrew Chen
Summary
Substack’s founders framed the company as a new economic engine for culture: a way for independent writers and creators to earn money, keep editorial freedom, and build a direct relationship with audiences. The guest argued that the 2020 media environment made that mission feel urgent, when firings, deplatforming, and fear around dissent pushed many writers out of legacy institutions. Substack’s appeal, in that view, was not just free speech, but a better business model for independent voices.
The discussion traced how the product evolved from a paid newsletter tool into a broader network. The guest said early purity around paid-only publishing gave way to free subscriptions, then to the realization that social platforms were still controlling distribution. That led to a push toward a first-party network with different incentives, where creators can reach audiences directly and take risks without being fully hostage to algorithms.
The conversation also focused on AI, attention, and the future of media. The guest argued that the scarce resource is now attention, not content, and that AI could either flood the internet with “slop” or give serious creators more leverage to make better work faster. On the capital side, the recent $100 million raise was described as funding a broader transformation of the product and company around that network vision.
Key takeaways
- The guest said Substack’s core value proposition is an economic engine that lets independent voices earn money without surrendering editorial control.
- The guest argued that 2020 exposed how fragile media independence was, and that Substack mattered because it protected writers when legacy institutions would not.
- The guest said the biggest platform risk is importing ad-tech incentives that put the company at odds with creators.
- The guest framed AI as a fork in the road: either more “AI slop” or much higher creative leverage for serious writers and podcasters.
- The guest said the recent $100 million raise is intended to rebuild Substack around a larger network and creator ecosystem.

How the episode opens
Let's talk a little bit about the the future of media. Are people going going to be reading less? Great writing, great media, great culture in general is this inherently valuable thing.
We've entered a world where attention is the scarce resource. There was one platform that stood up and said, "Hey, we are we are protecting free speech and that was Substack. This was also an era where like the blogging ecosystem was sort of dying.
A really important moment um to actually save blogging really and and sort of like writing on the internet. In the early days, people would often say to me in an accusatory tone, "Substack is just blogging with a business model. And I was like, you know, that sounds pretty good.
We've been talking a lot about disrupting media. What What are the big plans here? I aspire that the Substack app can be a place where you you look back at the time you spend on it and think, damn, I'm glad I did that.
That made me a better person. Catherine, we've been talking for years about how much we we we love Substack, even before we were formerly uh affiliated with the with the company. Um why don't you go first and talk about what you find so remarkable or striking about Substack's impact.
Yeah, I think the the impact is is truly understated. Um, and I think we've moved so fast as a country and as an internet and and as a world in the last few years that we've sort of memoryhold what it was like in 2020 2021, but particularly for media, how crazy the 2020 moment was for anyone in the thought leadership space, anyone in the media space. So, let me just go back to the summer of 2020.
