Bluesky discloses $100M Series B a year late, alongside CEO transition
What's the deal? Bluesky, the decentralised social network, has disclosed a $100 million Series B round led by Bain Capital CryptoDealroom has a profile for this one. Try Dealroom → — nearly a year after it closed in April 2025. The round also includes existing investors. Bluesky did not disclose its current valuation.
The timing of the announcement is deliberate: it comes one week after founder Jay GraberDealroom has a profile for this one. Try Dealroom → stepped down as chief executive officer, transitioning to chief innovation officer while the company searches for a commercially focused replacement.
Why now? Bluesky has grown rapidly since its $15 million Series A in 2024 — from 13 million to over 43 million global users. The AT Protocol (ATProto) underpinning the platform now powers a broader ecosystem of apps including video platform Skylight, Instagram alternative Flashes, and Flipboard's open social app Surf. Developer tools built on ATProto are downloaded over 400,000 times per month, and users access more than a thousand ATProto-powered apps every week.
The leadership transition signals a shift in ambition. Graber's departure from the CEO role suggests the board wants a leader focused on commercial growth, not just product vision — a common inflection point for social platforms that have built audience but not yet built revenue.
What could go wrong? The involvement of two crypto-oriented lead investors — Bain Capital Crypto and, previously, Blockchain Capital — may unsettle some users, given Bluesky's positioning as an open, decentralised alternative to ad-driven platforms. The company has not integrated cryptocurrency into its product and is not built on blockchain technology, but the investor profile could invite scepticism about future direction.
Finding a chief executive capable of monetising a decentralised social network without compromising the values that attracted its users is also a genuinely hard problem. The open social ecosystem Bluesky is building is technically novel but commercially unproven at scale.
The signal: Bluesky's raise reflects growing investor conviction that decentralised social infrastructure is a real category — not just a reaction to Twitter's turbulence under Elon MuskDealroom has a profile for this one. Try Dealroom →. ATProto's growing developer ecosystem, with 20 billion public records and over a thousand active apps, is beginning to resemble a platform in the meaningful sense.
The question is whether Bluesky can translate that ecosystem into a sustainable business without centralising control in ways that undermine its founding premise. The CEO transition suggests the company knows it needs to answer that question — and soon.
