A new European social network called Epsilon is set to launch on September 28, according to multiple reports. The platform is backed by former consultants from Sia Partners and aims to be an alternative to major global social networks, particularly focusing on competing with X (formerly Twitter). Epsilon’s interface is designed to resemble that of X, but it emphasizes being a European-based service, developed using European products and governed by European laws. The platform promises to keep user data within the European Union and to process it in compliance with the General Data Protection Regulation (GDPR), a strict data privacy law in the EU. Epsilon claims to use a moderation system called "a priori" moderation, which involves artificial intelligence to filter content before it is posted, with human verification for sensitive material. Unlike many major platforms, Epsilon states it will not use addictive algorithms—software designed to keep users engaged for longer periods—nor will it use "dark patterns," which are user interface techniques that trick users into making decisions they might not otherwise make. The platform also promises not to use psychological exploitation tactics. Users will have control over what they see and when they stop using the service. There are no advertising trackers, no user profiling, and Epsilon claims it will "sell no data." According to the platform’s "About" section, posts are displayed to users based on categories that align with their preferences. The service is designed to be open and interoperable, meaning it can connect with other platforms, and it promises that users "are never trapped," allowing them to take their audience with them if they leave. Epsilon is built on Mastodon, an open-source social network that supports decentralized communication, meaning no single entity controls the entire network. Stéphane Dubreuil, one of the co-founders of Epsilon, emphasized in an interview with France 24 in April 2026 that the platform is built on a foundation of respecting European rules. He acknowledged that while Epsilon may not be able to compete with the large global tech companies in terms of economic resources, it aims to provide a space for European users. Dubreuil criticized major platforms for potentially creating addictive behaviors, although no scientific study has definitively proven this claim. He also expressed concerns about how these platforms might influence democratic elections. Epsilon is funded by its own resources and private investors, with an estimated investment range of 50 to 100 million euros. Dubreuil noted that, when considering the scale of the 27 European Union countries, this amount is relatively small. Despite this, the platform’s focus on privacy, user control, and European governance may attract users looking for a different kind of social media experience.
