Social network Bluesky<\/a> is gearing up for big changes with today\u2019s news that the company raised $100 million in Series B funding. The round, led by Bain Capital Crypto, was closed in April 2025 but had not been disclosed until now.<\/p>\n Others that participated in the round include existing investors Alumni Ventures and True Ventures, plus Anthos Capital, Bloomberg Beta, and Knight Foundation. This round follows Bluesky\u2019s $15 million Series A<\/a>, led by Blockchain Capital and closed in 2024, and its $8 million seed round<\/a> from Neo<\/a> and other angel investors the year prior. Bluesky did not disclose its updated valuation.<\/p>\n The funding news has been strategically shared the week after Bluesky CEO Jay Graber announced she was stepping down<\/a> from the lead role and transitioning to become chief innovation officer. The move had signaled both Graber\u2019s desire to return to building and the need for the company to hire a chief executive who could drive Bluesky forward to commercial success.<\/p>\n Since its Series A, Bluesky has seen rapid growth from 13 million to, now, over 43 million global users. Its ecosystem of apps<\/a> that work on the AT Protocol (also known as ATProto) and interoperate with one another has also grown, from startups like the video app Skylight<\/a> or Instagram alternative Flashes<\/a> to larger companies like Flipboard, which has been building an open social app, Surf<\/a>. New communities<\/a> have also sprung up, like Blacksky<\/a>, which supports Black social media users.<\/p>\n The addition of another crypto-oriented VC firm may give some Bluesky users pause, however, especially since, so far, the company has not integrated cryptocurrencies into its offering. Bluesky isn\u2019t built on blockchain technology, either. Still, former CEO Graber\u2019s earlier work with the cryptocurrency Zcash helped inspire the social network\u2019s decentralized design, which has appealed to investors in the crypto space. <\/p>\n As Graber once told Wired<\/a> in an interview, \u201cthe term Web3 got very associated with cryptocurrency, so it\u2019s not a good word to use for what we\u2019re doing. But if you think about Web3 as evolving the social Web 2.0, that kind of\u00a0is<\/em>\u00a0what we\u2019re doing. We\u2019re evolving social media that was based in centralized companies into something that is open and distributed,\u201d she said last spring.<\/p>\n The additional funds have been used to scale Bluesky\u2019s team, while the company continues to develop Bluesky\u2019s app and the underlying ATProto<\/a> that powers it. This technology now powers a range of apps<\/a> in the larger open social ecosystem known as the Atmosphere \u2014 a network that contains around 20 billion public records, including posts, likes, comments, and other interactions, the company said on Thursday.<\/p>\n In addition, the number of developers building on ATProto is growing, as evidenced by the over 400,000 downloads of developer tools (SDK) seen every month. Plus, Bluesky says that people use over a thousand apps built on ATProto every week.<\/p>\n<\/div>\n
