Bluesky discloses $100 million Series B as user growth tops 43 million

Bluesky has disclosed a previously unannounced $100 million Series B round led by Bain Capital Crypto, a raise that was closed in April 2025 and is only being revealed now as the company enters a leadership transition.

The round included Alumni Ventures, True Ventures, Anthos Capital, Bloomberg Beta, and the 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 roughly $123 million. Bluesky did not disclose an updated valuation.

The funding was announced about a week after Jay Graber said she would step down as CEO and move into the role of chief innovation officer, with Toni Schneider taking over as interim chief executive while the board searches for a permanent replacement.

Since its Series A, Bluesky said its user base has climbed from 13 million to more than 43 million. The company also said the AT Protocol now supports an expanding network of apps beyond the main Bluesky client, including products such as Skylight, Flashes, Surf, and Blacksky.
