Substack is an online platform for journalists and writers to manage subscription-based newsletters. It has attracted a range of users who wish to connect with their audiences in a different way to social media or ad-based models, and boasts more than 35 million subscribers.
For an industry that has seen a steady decline in its fortunes since the rise of digital, Substack is a breath of fresh air. It allows journalists to avoid the clickbait-heavy models that have dominated the last decade, and provides more freedom than its competitors. Users produce their newsletters on the site for free, charging an optional subscription fee of which Substack takes 10%.
The company continues to seek out ways to diversify its offerings, whilst securing funding rounds to expand its reach. It has also taken an outspoken approach to the AI-generated content that is taking over the internet. It already provides its users access to an AI-detection tool, and is exploring other features such as enabling users to opt out of seeing AI-generated content on their feeds altogether.
