> Decentralized social network built on the AT Protocol; it disclosed a $100M Series B in March 2026, although the financing closed in April 2025.

## Why it 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.
