Bluesky raises $100M Series B led by Bain Capital Crypto as CEO Jay Graber steps down

Bluesky raised $100M in Series B funding in a round led by Bain Capital Crypto, closed in April 2025, but disclosed this week alongside the news that CEO Jay Graber is stepping down to become chief innovation officer, with the company now searching for a leader focused on commercial growth. The round also included Alumni Ventures, True Ventures, Anthos Capital, Bloomberg Beta, and Knight Foundation, and follows a $15M Series A in 2024 and an $8M seed round the year prior. Since its Series A, Bluesky has grown from 13 million to over 43 million global users, with its underlying AT Protocol now powering more than a thousand third-party apps used every week and a broader ecosystem containing around 20 billion public records.
