Periwinkle, a Berlin-based startup, is making it easier for individuals to set up self-hosted social media accounts on their own domain, using the AT Protocol, the same open-source technology that powers Bluesky.
Periwinkle aims to provide the necessary infrastructure for users to run their own social media, allowing them to have an account on their own domain, with the ability to store their data, including posts, follows, and user profiles, on their own Personal Data Server (PDS).
The company offers domains for purchase and handles server updates, backups, and monitoring, making it easier for non-technical users to transition to self-hosted social media.
The Funding and Market Context
Periwinkle is currently self-funded, with founder Charles Blumenthal, a former software engineer at McKinsey, chatting with investors in Europe. The company has not disclosed any funding rounds.
The growth of AT Protocol-powered app Bluesky, with over 43 million registered users, demonstrates the demand for decentralized social media solutions. Periwinkle’s premium plans start at $4 per month, with a free plan also available.
Product Details
Periwinkle’s plans include support for multiple handles, storage, and real-time backups, with the option to host in the E.U. or the U.S. Custom enterprise plans are also available.
The company aims to add more tools, such as automated post deletions and archiving tools, over time, making it an attractive option for those who want more granular control over their social media accounts.
What This Means for the Industry
Periwinkle’s solution could be particularly useful for public officials, political candidates, or businesses that require more control over their social media presence. As the demand for decentralized social media continues to grow, Periwinkle is well-positioned to capitalize on this trend.
