An end-to-end encrypted workspace for email, docs, and calendar, now part of Notion.

Overview

Skiff was a leading privacy-focused productivity suite that provided end-to-end encrypted (E2EE) alternatives to Gmail and Google Workspace. It unified encrypted email, collaborative documents, and a calendar into a single, high-security dashboard. After achieving rapid growth and reaching over 2 million users, the platform was acquired by Notion in early 2024 to lead their security and encryption efforts.

Why it works

Privacy: One of the few suites where encryption is applied not just to email, but to documents and files.
User Experience: Built with a modern, high-performance UI that rivals the 'Big Tech' tools it replaces.
Decentralization: Integrated with IPFS (InterPlanetary File System) for high-resilience data storage.
Trust: Leverages open-source encryption standards to build user confidence.

Founder story

Founded in 2020 by Andrew Milich and Jason Ginsberg in San Francisco. Andrew and Jason, both software engineers, believed that 'privacy shouldn't be a premium.' They built Skiff to make professional-grade encryption as easy to use as a standard email account, eventually reaching 2M+ users before joining Notion.
