07 Team — Building block

Work together — without someone else's cloud.

Chat, video calls, files and office: all in-house, all yours.

Message a colleague, start a video call, share a file, edit a document together — all in your own apps. Nothing sits with an external vendor, nobody reads along. And it feels like the tools you already know.

From everyday work

The shop-floor chat that doesn't land at a foreign tech giant

The early shift reports a fault in the group chat, attaches a photo, maintenance replies with a voice message — and in the afternoon the same quote gets finished together in a browser document. All on your own server. No per-seat licence, no data overseas.

How it fits together technically +

A federated messenger with end-to-end encryption, groups, video calls and bridges to other systems. Files, calendars and contacts via your own file cloud with desktop and phone sync. Documents, spreadsheets and slides are edited together, simultaneously, in the browser. Diagrams and sketches happen right next to them. Federation means you stay reachable to the outside world without chaining yourself to one vendor.
