TeamDavid: sovereignty score and 8 European alternatives

TeamDavid is the groupware of Tobit.Software, based in Ahaus, Germany. It combines email, chat, video and tasks in one application and is presented by the vendor as groupware, email and messaging on-premise. Organisations install it on their own servers and manage users and mailboxes themselves. The product is aimed at companies, organisations and municipalities that want to run their team communication in-house.

Tobit.Software has developed and sold standard software since 1986 and is based in Ahaus. The vendor describes its communication platform as GDPR-compliant and developed in Germany. Because the software runs on the customer's servers, message content stays under the organisation's own control, and German law and EU data protection rules apply to the vendor. The product is not open source.

Why digital sovereignty matters with TeamDavid

TeamDavid is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

TeamDavid runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

TeamDavid is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs TeamDavid together with your other vendors and gives a total score, a heatmap and the main risk drivers.
