How Substack is trying to balance the constraints of its own ideology of putting authors and readers first with its commitment to growth via its new mobile app
In the Spring of 2018 I got invited by the CEO of Substack to come to Toronto for a couple days to hang out with the whole team … Tweets: @nbashaw , @shortformernie , @navalang , @faris , @marshallk , @sifter , and @noahchestnut Tweets: Nathan Baschez / @nbashaw : I keep seeing people misunderstand @SubstackInc They model the company as if a random YouTube PM was running the show, following the typical aggregator playbook But Substack is an ideology-driven company https://t.co/MORZDFqXp1 Ernie Smith / @shortformernie : I admit to some degree I get pissy about Substack because I want the open internet to win and platforms, naturally, represent a challenge to this. @nbashaw, a former Substacker who I have a lot of respect for, makes the case for the Substack way. https://every.to/... Navneet Alang / @navalang : This is super interesting. Tricky thing is that the ideological bent - not to mention unclear funding of certain writers - has associated Substack with a more right-leaning crowd when it comes to “free speech.” https://twitter.com/... @faris : “The point isn't just to make money—it's to change the systems that human attention flows through. You can't understand @Substack without understanding this.” HT @neilperkin https://every.to/... Marshall Kirkpatrick / @marshallk : Excellent insider analysis of the new publishing and reading platform that is Substack https://every.to/... Alex Watson / @sifter : This is a great piece of product analysis; it's positive whole also being sceptical (see the tension between whether Substack users subscribe to more newsletters because of Substack itself or because they're newsletter fans) https://twitter.com/... Noah Chestnut / @noahchestnut : definitely worth reading @nbashaw as he was the first “non-founder” hire at Substack and Nathan's framing of “what would a generic YouTube PM do?” is a helpful tool to simulate the devil's advocate and just call out a variety of biases / assumptions. https://twitter.com/...
Context & Ripple Effects
Substack has spent years defending a specific identity: founders told Columbia Journalism Review it is a platform, not a media company, and Stratechery framed the controversies around it as missing that it is merely a tool for sovereign writers paid directly by subscribers. The new mobile app is the first major product move that strains that framing, because an app is inherently a curated surface — someone at Substack decides what readers see first.
The strain is not hypothetical. When Substack paid certain writers to join, critics read it as an editorial act, and the company's own defense was that leaders decide what kind of writing to support (an editorial choice). An app with recommendations makes that kind of choice continuously rather than occasionally.
First-order effects
- Writers who joined for direct subscriber relationships now share shelf space with an algorithmic or hand-curated app feed, so Substack gains a distribution lever over its 'sovereign' authors that email never gave it.
- Readers get a discovery surface inside Substack for the first time, shifting the product from a newsletter inbox tool toward something closer to the social reading apps the company has positioned itself against.
Second-order effects
- Rival newsletter and creator-subscription platforms must now answer whether they will build competing reader apps, turning mobile distribution into the new battleground instead of email deliverability and pricing.
- Every curation call in the app invites the same scrutiny as the Pro program did — Wired UK already noted many top earners are polarizing deplatformed figures, so whatever the app surfaces becomes a moderation-adjacent story whether Substack wants one or not.
Third-order effects
- If growth keeps requiring curation, the platform-versus-media-company distinction erodes structurally: Substack ends up making editorial decisions at scale, just distributed through software instead of mastheads.
- The deeper pattern is that subscription businesses hit a point where serving existing writers and acquiring new readers pull in opposite directions — the app is Substack choosing acquisition, and other creator platforms will face the same fork.
The trend: Creator-economy platforms are discovering that scaling subscriptions eventually forces them to adopt the aggregation mechanics their founding ideology rejected.
