About Wimi
Wimi is a French collaborative suite that bundles project workspaces, team messaging, calendars and document management. Its file component, Wimi Drive, turns the suite into a Dropbox/Google Drive/OneDrive alternative: it syncs workspace documents to Windows and macOS desktops, supports file and folder versioning, shareable internal and external links with edit or view-only rights, and uploads of up to 2 GB per file. The free plan covers up to three users with 10 GB of storage; paid Workplace plans start at €3 per user/month (25 GB) and scale to 100 GB on Pro, while the Enterprise tier adds SSO, API access and unlimited storage. Mobile apps cover iOS and Android alongside the web client.
Wimi's positioning rests on digital sovereignty: the publisher, Cloud Solutions SAS (Paris), operates its own ISO 27001-certified datacenters in France (Île-de-France and Hauts-de-France) rather than renting US hyperscaler capacity, and states that customer data, metadata and backups never leave the European Union. It is ISO 27001:2022 certified and markets HDS compliance for health-data hosting, with SecNumCloud qualification publicly stated as in progress rather than obtained. For buyers who want a French-hosted, EU-controlled storage and collaboration base, Wimi is a strong sovereign option, with the caveat that storage is one module of a broader teamwork product rather than a pure file-sync tool.
