CryptPad is the canonical end-to-end-encrypted open-source collaboration suite, actively developed by a team at XWiki SAS, a Paris-based French company that has been building open-source software since 2004. The platform delivers a Google Docs / Notion / Microsoft Office Online alternative built around zero-knowledge encryption: documents are encrypted on the user's device before any data leaves it, and XWiki itself has no ability to read customer documents. The product surface covers rich text, code, slides, forms, kanban, calendar, polls, whiteboard, sheet, and team drives: a complete office-suite-grade feature set running entirely E2E.
Funding architecture is the structurally interesting story. CryptPad is funded by NLnet PET, NGI TRUST, NGI DAPSI, and the NGI Zero Commons Fund, the European Commission's Next Generation Internet (NGI) programme that channels EU public-research money into European-sovereign open-source infrastructure. Additional funding comes from CryptPad.fr subscribers and Open Collective donations. This combination (EU public funding + community subscriptions) gives CryptPad a structurally different cap table from any US-VC-funded competitor: no exit pressure, no dilution risk, no acquisition rumours, and explicit alignment with the European Commission's sovereign-tech agenda.
Pricing for CryptPad.fr (the managed cloud) is freemium with paid storage tiers; the entire codebase is open source on GitHub (cryptpad/cryptpad) and self-hostable for organisations wanting full control. Best fit: privacy-maximalist EU teams, journalists and activists, EU public-sector and education buyers (where NLnet / NGI funding lineage is itself a procurement signal), and any organisation that wants a full office suite where the vendor structurally cannot read the documents.
