Ten days after founder Jay Graber stepped aside as CEO, the decentralised social platform has disclosed a $100 million Series B led by Bain Capital Crypto, a round that closed last April but was never announced. The timing tells its own story.
There is a quiet irony in the fact that the person who built Bluesky shares her given name with it. Lantian Graber -“blue sky” in Mandarin, a name her mother gave her as a wish for boundless freedom, spent four years turning a Twitter research project into a platform of over 43 million users, a functioning decentralised protocol, and a genuine alternative to the platforms her users had fled. Then, on March 9, 2026, she stepped back.
The company announced on Thursday that it had raised $100 million in a Series B round led by Bain Capital Crypto, with participation from Alumni Ventures, True Ventures, Anthos Capital, Bloomberg Beta, and the Knight Foundation. The round closed in April 2025. Bluesky is only disclosing it now.
The gap between closing and announcing is itself worth pausing on. For most startups, fresh funding is a press release and a celebratory tweet. Bluesky’s choice to sit on $100 million for nearly a year, and to surface it only after a leadership transition, suggests a company more focused on building than on performing momentum.
That leadership now belongs, on an interim basis, to Toni Schneider. The former CEO of Automattic, the company behind WordPress.com, and a partner at True Ventures, Schneider had been advising Graber and the company for over a year before agreeing to step in as the board runs a permanent search.
Graber, for her part, is not going anywhere: she moves into a newly created role as chief innovation officer, focused on building out the AT Protocol, the open social infrastructure that underpins Bluesky’s ambitions.
The split is, by tech company standards, unusually clean. Graber’s own framing was precise: “As Bluesky matures, the company needs a seasoned operator focused on scaling and execution, while I return to what I do best: building new things.” That is not the language of a forced exit. It is the language of a founder who knows what she is good at and, more unusually, what she is not.
Graber was hired by Jack Dorsey in August 2021 to lead what was then a Twitter-funded research initiative into decentralised social media. When she incorporated the project as an independent company later that year, she inherited both an audacious technical premise and a nearly impossible PR challenge: how do you build a decentralised network for people who are, by definition, not yet there?
She managed it. By the time of its $15 million Series A, led by Blockchain Capital in October 2024, the platform had 13 million users. It now has 43 million.
The jump from $15 million to $100 million in a single round reflects more than user growth. It reflects a shift in how investors are reading the decentralised social space, and specifically, Bluesky’s position within it. Where early rounds were bets on a protocol and an idea, this one is a bet on a platform with real scale and a community with demonstrated loyalty.
Bain Capital Crypto’s lead role is worth noting. The firm invests across crypto and web infrastructure, and the AT Protocol, which separates a user’s identity, data, and social graph from any single application, has structural similarities to blockchain-era promises of user ownership, but with far more practical traction.
Knight Foundation’s involvement signals that the press freedom and open-internet communities continue to see Bluesky as infrastructure worth backing, not merely a product.
The money arrives at a moment when Bluesky needs to resolve a tension it has so far managed to defer: how does a platform that has built its identity around rejecting surveillance advertising and algorithmic manipulation actually make money?
The company’s stated model involves subscription services and domain registration fees, functional, but modest. It has not yet demonstrated that this can support a company of its ambitions at the scale it is reaching.
Schneider’s appointment is, in part, an answer to that question. Automattic navigated a similar challenge: it built a massive open-source ecosystem around WordPress and then constructed a sustainable commercial layer on top of it, largely through premium hosting and business services.
If Bluesky follows a comparable path, open protocol beneath, paid services above,it has a template. Whether social networking, with its shorter attention spans and higher churn, tolerates the same approach is not obvious.
The competitive context has shifted considerably since Bluesky’s early days as a curiosity for journalists and tech workers fleeing Elon Musk’s rebranded X. Meta’s Threads, which uses the rival ActivityPub protocol and has been gradually federating with the broader Fediverse, has grown into a formidable alternative with a user base an order of magnitude larger. X itself remains the dominant venue for real-time public discourse, despite persistent predictions of its collapse.
Bluesky’s differentiator has always been structural rather than purely social. The AT Protocol’s architecture, in which a user’s identity and social graph are portable, not locked to any single server, is meaningfully different from both X’s centralised model and Mastodon’s federated but technically demanding alternative.
What is clear is that the company Graber built has survived its first real test: not the technical challenge of building a decentralised protocol, which it managed, but the organisational challenge of outgrowing its founder without losing what made it worth building in the first place. Schneider’s job is to turn that survival into something more permanent. The AT Protocol, and the 43 million people who have joined so far, will be watching.
