Decentralized social app Bluesky announced on Thursday that it has raised a $15 million Series A round, following its $8 million seed raise last year. This funding comes as Bluesky sees increased growth, in part from X users who are troubled by recent changes to the block feature, as well as the move to allow third parties to train AI on users’ public posts. Within the last month alone, Bluesky has added around 3 million new users, bringing its total user base to about 13 million.
