Can a platform built on direct subscriptions survive the shift toward social media features?
In short: Founded in 2017 to help writers monetize newsletters, Substack has evolved from a simple publishing tool into a complex media ecosystem. While it promises creators independence and direct revenue, its expansion into video, social networking, and controversial content moderation has sparked intense debate about the platform's future and its societal impact.
Substack was launched in San Francisco by Chris Best, Jairaj Sethi, and Hamish McKenzie, drawing inspiration from subscription-based models like Ben Thompson’s Stratechery. By providing infrastructure for payments, design, and analytics, the platform aimed to offer journalists and experts a more stable alternative to traditional media, which faced a significant decline in newsroom jobs between 2004 and 2019. Early growth was fueled by recruiting high-profile writers and offering stipends, though critics noted that the majority of content focused on personal writing and analysis rather than original reporting.
The platform's business model relies on a 10% cut of subscription revenue, with creators retaining control over their pricing and audience. By March 2025, the company reached five million paid subscriptions, and by October 2025, it reported that 50,000 creators were earning money, with at least 50 individuals generating over $1 million annually. Despite this financial success, Substack has faced repeated scrutiny over its 'lightweight' moderation policies. The founders have consistently defended their commitment to minimal censorship, even as the platform became a home for controversial figures, including those accused of spreading misinformation or promoting extremist views.
In recent years, Substack has aggressively pivoted toward social and multimedia features. Following the introduction of Notes, a microblogging tool, and the expansion of video capabilities, the company has increasingly resembled a social network. This shift, coupled with a $1.1 billion valuation in 2025, signals an ambition to move beyond newsletters. However, this expansion has brought new challenges, including security breaches and tensions with creators who have threatened to leave over the platform's refusal to deplatform extremist content. As Substack integrates advertising and standalone TV apps, it remains a contested space where the promise of creator autonomy clashes with the realities of managing a massive, diverse digital community.
