Stream E2EE - Zero-Knowledge Team Collaboration Platform
Stream E2EE logo

Overview

Stream E2EE is YPYM’s sovereign, zero-knowledge end-to-end encrypted (E2EE) communication and team collaboration platform. Engineered on open cryptographic standards and the decentralized Matrix federation protocol, Stream ensures that internal communications, strategic workflows, proprietary files, and executive discussions remain cryptographically sealed against external observation. Unlike centralized consumer messaging services, Stream operates entirely on private, dedicated enterprise infrastructure with zero reliance on third-party identity servers, third-party push telemetry, or unencrypted database stores.
Stream E2EE is an internal enterprise collaboration product. Learn more at suite.ypym.app/stream-e2ee.
Stream E2EE Real-time Platform Interface

Live production interface of the Stream E2EE collaboration client (stream.ypym.app) displaying active enterprise rooms such as #cre-nobu, #hidden-page-seo, and #ink-and-thought. A dedicated real-time thread panel demonstrates ongoing discussions on digital banking article revisions and search performance justifications under complete Matrix Olm/Megolm encryption. All message payloads, media attachments, and state events remain cryptographically sealed at rest without external telemetry exposure.

Client Platforms

Stream E2EE is accessible across web, desktop, and mobile operating systems:

Web / Desktop

Core Capabilities

string
default:"Olm / Megolm"
Double Ratchet cryptographic protocol (Olm) for 1:1 direct sessions and Megolm ratcheted trees for high-scale encrypted group rooms.
boolean
default:"true"
Message payloads, event DAG states, and media attachments are persisted exclusively in encrypted ciphertext on backend storage layers.
boolean
default:"true"
