Bluesky Social PBC

Bluesky is a social app that is designed not to be controlled by a single company, built on the AT Protocol, an open-source toolbox for building social apps that can all talk to each other. The company positions itself as building an open foundation for the social internet, giving users choice in their experience, creators independence from platforms, and developers the freedom to build. It states a commitment to ensuring that the social network can never be bought by a single individual or organization. Bluesky raised a $100 million Series B in April 2025 led by Bain Capital Crypto, and reported growing from 13 million to over 43 million global users since its Series A. Jay Graber stepped back as CEO to become Chief Innovation Officer, with Toni Schneider serving as interim CEO from March and later named permanent CEO.
