Company Overview

About Bluesky

Bluesky is a decentralized social network built on the AT Protocol, an open standard designed to give users control over their data, identity, and feed algorithms. Originally incubated by Twitter and spun out as an independent company, Bluesky raised $100 million in Series B financing in March 2026 led by Bain Capital Crypto, following a CEO transition that positioned the company for its next growth phase.

Business Model & Competitive Advantage

The platform has grown to 43 million users, up from 13 million at its Series A, with 400,000+ AT Protocol SDK downloads per month and over 1,000 third-party applications built on its ecosystem. Bluesky's open architecture allows developers to build alternative clients, custom feeds, and entirely new social applications on top of the protocol — a structural advantage over walled-garden competitors.

Competitive Landscape 2025–2026

Bluesky represents the only credible decentralized challenger to X (formerly Twitter) at meaningful scale. Its growth accelerated sharply during X's turbulent ownership transition period, and the AT Protocol's open architecture has attracted a developer community committed to building a federated, user-owned social web. The Series B positions Bluesky to expand internationally and deepen developer tooling.
