Bluesky Announces $100 Million Series B, User Growth Raises 43 Million
Bluesky announced a $100 million Series B round led by Bain Capital Crypto, a raise that closed in April 2025 and is now being announced as the company enters a leadership transition.
The round included Alumni Ventures, True Ventures, Anthos Capital, Bloomberg Beta and Knight Foundation. It follows Bluesky's $15 million Series A in October 2024 and an $8 million seed round in 2023, bringing total disclosed funding to approximately $123 million. Bluesky did not disclose the revised assessment.
The fund announced Jay Graber will move from CEO to chief innovation officer, with Tony Schneider acting as interim CEO while the board seeks a permanent replacement.
Since the S Series A, Bluesky's user base has grown from 13 million to 43 million. The company also says the AT protocol now supports a wider range of applications beyond the original Bluesky client, including products such as Skylight, Flash, Surf and BlackSky.
