Social network Bluesky raised $100 million in Series B funding led by Bain Capital Crypto, with participation from existing investors Alumni Ventures and True Ventures, plus Anthos Capital, Bloomberg Beta, and Knight Foundation.
Bluesky did not disclose its valuation.
The Series B funding round was closed in April 2025, but had not been disclosed until today.
This Series B round follows Bluesky’s $15 million Series A round, led by Blockchain Capital and closed in 2024, as well as its $8 million seed round in 2023, backed by Neo (an American technology startup accelerator and venture capital firm based in San Francisco) and other angel investors.
Including the latest round, Bluesky has raised more than $121 million in fudning to date.
Since its Series A, Bluesky has reported a growth from 13 million to, now, over 43 million global users for its platform. Bluesky said it used the funds to scale its team and build its technology that now powers a range of apps in the larger open social ecosystem known as the Atmosphere — a network that contains around 20 billion public records, including posts, likes, comments, and other interactions.
