What Cozy Cloud does

Cozy Cloud is a Paris-based, open-source personal cloud platform founded in 2011 and now operating as Twake Workplace following a July 2025 rebrand. The platform provides individuals and organizations with a unified workspace combining cloud storage (Twake Drive), messaging (Twake Chat, Matrix-based), email (Twake Mail, JMAP-based), password management (Twake Pass, Bitwarden-based), collaborative notes (Twake Notes), and supplementary apps for banking, photos, contacts, OCR document scanning, and carbon tracking. Its technical backbone is built on Node.js, CouchDB, and React, with client-side encryption via the W3C WebCrypto API (PBKDF2/SHA-256, AES-256-GCM, AES-KW) and Docker-based self-hosting for full data sovereignty. A growing library of automated konnectors pulls structured data from banks, insurers, ISPs, government services, and education platforms.

The company monetizes via a freemium model with free cloud storage and optional paid upgrades for expanded capacity, supplemented by a sales-assisted enterprise motion for organizations requiring custom deployments and on-premise self-hosting. Customer segments span privacy-conscious individual users, the European education vertical (notably a ~5,000-seat pilot with Académie de Rennes and ~1,000-seat pilot at Lycée de Vitré), enterprises seeking a European alternative to US hyperscalers, and government/public-sector organizations pursuing digital-inclusion programs. All user data is hosted in France and the platform is GDPR-compliant, with MyData Operator certification reinforcing its positioning in data-sovereignty procurement contexts.

In May 2025 Cozy Cloud was acquired by LINAGORA, a French open-source software group that also operates Twake Mail, Twake Chat, LinTo, and Linshare, bringing the company into a broader strategic portfolio. Differentiated AI capability is delivered through the DISPERS protocol developed with INRIA Saclay, enabling decentralized model training on personal data without centralization, alongside practical AI features such as OCR-based document scanning, banking transaction categorization, and AI-driven photo organization. Revenue is not publicly disclosed and the company remains a small team of 11–50 employees with no disclosed VC funding since 2016.

Core offering

Cozy Cloud (now operating as Twake Workplace) provides a personal cloud platform that combines file storage, messaging, email, password management, and collaborative notes in an open-source environment with client-side encryption and data hosted in France. The platform aggregates personal data from third-party services via automated connectors and supports both self-hosting via Docker and a managed cloud service.

Product overview

Cozy Cloud operates as a personal cloud platform that rebranded to Twake Workplace in 2025. The offering combines a core workspace platform with integrated modules including Twake Drive (cloud storage), Twake Chat (Matrix-based messaging), Twake Mail (JMAP email), Twake Pass (Bitwarden-based password manager), and Twake Notes (collaborative notes). Supporting applications include Cozy Banks for financial management, Cozy Photos for photo sharing, Cozy Contacts for address book management, and Mes Papiers for document scanning with OCR. The platform offers developer tools including Cozy Stack (backend server), Cozy Client (JavaScript SDK), and a REST HTTP API. An advanced privacy-preserving AI initiative called DISPERS enables decentralized AI model training without centralizing user data.

Direct peers

• Nextcloud: Open-source personal cloud and collaboration platform offering file sync, chat, mail, and office productivity with self-hosting and managed cloud options. Most direct competitor to Cozy/Twake Workplace, with comparable open-source DNA, self-hosting via Docker, and European roots.
• ownCloud: Open-source file sync, sharing, and collaboration platform targeted at enterprises and service providers. Competes directly with Cozy's Twake Drive on self-hostable personal cloud storage and data sovereignty, with overlapping open-source architecture and connector ecosystem.
• Element (Matrix): Decentralized secure messaging built on the Matrix protocol. Twake Chat is also built on Matrix, making Element a direct comparable for the messaging layer and a broader peer in the privacy-focused, federated communications space.
• Proton: Swiss-based privacy-focused suite offering Proton Mail, Proton Drive, Proton Pass, and Proton Calendar. Direct competitor on the bundled privacy cloud proposition, with stronger consumer brand and end-to-end encryption across multiple product modules.
• Bitwarden: Open-source password manager that is the underlying protocol for Twake Pass. Direct peer in the encrypted credential management space and a comparison point for Cozy's password manager offering, though Bitwarden is more mature commercially.
• Seafile: Open-source cloud storage and collaboration platform with self-hosting and enterprise deployment options. Comparable to Twake Drive in providing file sync, sharing, and team collaboration on self-managed infrastructure, with similar encryption and data sovereignty positioning.
• Tresorit: Swiss-Hungarian zero-knowledge cloud storage and file sharing service for individuals and businesses. Direct peer in the end-to-end encrypted cloud storage category, with comparable security architecture and European regulatory moat.

Regional players

• Infomaniak: Swiss cloud provider offering email, hosting, collaboration, and storage services with strong data sovereignty and ecological positioning. Comparable to Cozy as a European privacy-focused alternative to GAFA, though primarily serving the Swiss market and operating at larger scale.

Emerging players

• ONLYOFFICE: Open-source office and collaboration suite integrated with Cozy's Twake Drive for document editing. Adjacent competitor in the European open-source productivity space, with comparable sovereign infrastructure positioning and overlapping customer base in regulated industries.

Broad incumbents

• Google Workspace: Hyperscale productivity suite (Gmail, Drive, Docs, Chat, Meet) competing with the full Twake Workplace bundle. While not niche-aligned, it represents the dominant incumbent whose privacy and sovereignty limitations Cozy explicitly positions against.
