Keybase

Keybase is a security‑focused platform that provides end‑to‑end encrypted communication and collaboration tools. Its core offerings include encrypted chat, secure file sharing, team workspaces, and encrypted Git repositories. The service also supplies an identity‑verification layer that lets users prove ownership of social‑media accounts, domains, or Bitcoin addresses by linking them to PGP keys. These tools are aimed at individuals, developers, and organizations that require confidentiality and authenticity in their digital interactions. Keybase markets its products primarily to privacy‑conscious users and to teams that need secure collaboration without relying on third‑party trust.

The company is headquartered in the United States of America, a detail explicitly noted in the supplied context. Keybase was founded in 2014 and remained an independent entity until May 2020, when it was acquired by Zoom Video Communications. After the acquisition, Keybase continued to operate as a distinct product within Zoom’s portfolio, maintaining its own client applications and encryption protocols. No public figures for total users or revenue have been disclosed in the available sources.

Keybase distinguishes itself by binding cryptographic keys to verifiable online identities, a process that uses proofs posted on platforms such as Twitter, GitHub, Reddit, and DNS records. Its filesystem, known as Keybase Filesystem (KBFS), provides an end‑to‑end encrypted, version‑controlled store that appears as a regular folder on users’ devices. In addition to chat and file sharing, the platform offers encrypted Git repositories that enable developers to collaborate on code without exposing contents to the server. The service also incorporates anti‑spam mechanisms; following the 2019 Stellar Lumens airdrop incident, Keybase tightened registration controls and announced a “walled garden” mode that limits unsolicited messages, team invites, and follower requests to pre‑existing connections. This approach aims to reduce abuse while preserving usability for legitimate contacts.

Structurally, Keybase operates as a subsidiary of Zoom after the 2020 acquisition, while retaining its original brand and technical infrastructure. The company’s development is guided by the cryptographic expertise of its founding team, which includes Chris Coyne and Max Krohn. The platform’s codebase is largely open source, allowing independent audits of its encryption implementations. No further details about ownership hierarchy or subsidiary relationships are publicly disclosed in the available sources.
