Substack is an American online platform that provides publishing, payment, analytics, and design infrastructure to support subscription-based content, including newsletters, podcasts, and video. It allows writers to send digital content directly to subscribers. Founded in 2017, Substack is headquartered in San Francisco. The company has faced criticism for its content moderation policies, as well as security breaches involving user data. ==History== Substack was founded in 2017 by Chris Best, the co-founder of Kik Messenger; Jairaj Sethi, a head of platform and principal developer at Kik Messenger; and Hamish McKenzie, a former PandoDaily tech reporter. Best and McKenzie have said Ben Thompson's Stratechery, a subscription-based tech and media newsletter, was a major inspiration for their platform. Best acts as CEO of the company. In 2019, Substack added support for podcasts and discussion threads among newsletter subscribers. By November 2021, the platform said it had more than 500,000 paying subscribers, representing over one million subscriptions. In January 2022, Substack announced that it would begin private beta testing of video functionality on its platform. In November, it launched Substack Chat, where content creators could create private group chats with subscribers. The same year, the company launched the Substack Reader app for iOS, followed by an Android version six months later. In April 2023, Elon Musk spoke with Substack's leadership about purchasing the platform, but his offer was rejected. The same month, Substack implemented a Notes feature, which allows users to publish and repost short-form content. This microblogging feature has been compared to Twitter, and many outlets considered it a response to changes at Twitter under Musk's ownership. Musk criticized Substack Notes, and Twitter began censoring links to Substack. In November 2023, Substack introduced new video creating and editing tools, and content creators started launching original shows on the platform. In April 2024, Substack partnered with Spotify to enable podcasters to distribute episodes on both platforms and added new editing features for podcasts. In June 2024, Substack announced a year-long development initiative for TikTok creators called Creator Studio, and added five-minute video capabilities to the chat function. Video was also added to Notes. By November 2024, Substack had four million paid subscriptions. Substack added livestreaming options for creators in September 2024. Following this and the January 2025 restrictions on TikTok in the United States, Substack announced the ability to post and monetize videos directly through the Substack app in February 2025. In March 2025, Substack announced that it had five million paid subscriptions. In June, independent journalist Eric Newcomer reported that Substack was in talks to raise a new funding round. The New York Times later reported that Substack had raised $100 million, valuing the company at $1.1 billion. The investors in this round were Andreessen Horowitz, BOND, The Chernin Group, Skims, and Klutch Sports Group. In July 2025, The New York Times reported that Substack was investing heavily in social-network features and planned to expand advertising. In January 2026, the company announced Substack TV, a standalone app for Apple TV and Google TV that will support videos and livestreams. According to TheWrap, the beta app allows Substack subscribers to watch creators' video posts and livestreams. The app can be used by both free and paid Substack subscribers, with access to content based on subscription tiers. ==Finances== Authors can decide to make subscribing to their newsletter free or paid, and to make specific posts publicly available to non-subscribers. , the minimum subscription fee was $5/month or $30/year, and Substack usually takes a 10% cut from subscription payments. In October 2025, Substack reported that 50,000 creators were earning money on its platform, of whom at least 50 were making more than $1 million. Substack earns no revenue from advertisements placed by publishers. In February 2019, the platform began allowing creators to monetize podcasts. Substack reported 11,000 paid subscribers as of 2018, rising to 50,000 in 2019. Substack raised an initial seed round in 2018 from investors including The Chernin Group, Zhen Fund, Twitch CEO Emmett Shear, and Zynga co-founder Justin Waldron. Andreessen Horowitz provided $15.3 million in Series A funding in 2019, some of which went to bringing high-profile writers into Substack's network. Substack has provided some content creators with advances to start working on their platform. In 2019, the site provided a fellowship to some writers, which included a $3,000 stipend and a one-day workshop in San Francisco. The decline of sports-oriented publications such as Sports Illustrated, Deadspin, and SB Nation, coupled with the onset of the COVID-19 pandemic, led to a surge in sports journalists moving to write on Substack in 2019 and 2020. Substack competes with subscription site The Athletic in this submarket, so McKenzie says the company recruits less strongly in that market. In 2020, after the onset of the pandemic, Substack extended grants of $1,000–$3,000 to over 40 writers to begin working on the platform. It expanded into comics content in 2021 and signed creators including Saladin Ahmed, Jonathan Hickman, Lee Knox Ostertag, Scott Snyder, and James Tynion IV, paying them while keeping their subscription revenue. After their first year, Substack will take 10 percent of subscription revenue. Substack's founders reached out to a small pool of writers in 2017 to acquire its first creators. Bill Bishop was among the first to put his newsletter, Sinocism, on Substack, offering its daily content for $11 a month or $118 a year. As of 2019, Bishop's Sinocism was the top-paid newsletter on the service. By late 2020, the conservative newsletter The Dispatch became the top Substack user, with more than 100,000 subscribers and over $2 million in first-year revenue, according to founder Steve Hayes. In May 2021, Substack acquired Brooklyn-based startup People & Company. In August 2020, Substack reported that over 100,000 users were paying for at least one newsletter. As of August 2021, Substack had more than 250,000 paying subscribers and its top ten publishers were making $7 million in annualized revenue. In April 2022, The New York Times reported Substack may be valued at $650 million. Substack dropped an effort to raise money in May 2022. The company had aimed to raise between $75 million and $100 million. ==Criticism== ==See also== Beehive Forum Blogger Ghost Medium WordPress ==References== ==External links==
