Overview
Bluesky operates a social network and develops the open AT Protocol for interoperable social applications. The company announced a $15M Series A in October 2024 led by Blockchain Capital. In March 2026, it disclosed that a $100M Series B led by Bain Capital Crypto had actually closed in April 2025. Alumni Ventures participated in both rounds.
At the time of the March 2026 announcement, Bluesky reported more than 43M global users, over 1,000 apps using AT Protocol each week and roughly 20B public records in the ecosystem. These are company-reported usage metrics, not paying subscribers, revenue or profitability.
Why Bluesky is interesting
Bluesky separates a consumer social app from a portable social protocol. Its financing creates an unusually clear investment trail: the company names Alumni Ventures in both its 2024 Series A and 2025 Series B, but did not disclose how much AV invested.
Product & use cases
Bluesky is a consumer microblogging service with custom algorithmic feeds, user-managed identity and account portability built on the AT Protocol. Independent apps can use its protocol, reducing dependence on one platform operator.
- Public posts, conversations and community discovery
- Portable identity and custom feeds across compatible AT Protocol services
- Open social infrastructure for third-party developers

Competitive landscape
Edge: Open social infrastructure and a growing developer ecosystem could reduce platform lock-in, but users and developers may still concentrate on the dominant Bluesky app.
The central question is whether protocol openness and user portability foster a durable, engaged ecosystem that Bluesky can operate sustainably. User registrations are not revenue; subscribers, monetization, server costs and retention remain separate diligence questions.
