Why Liman

Work sovereign. As a team.

One client for collaboration — data in the EU or on your side, AI that knows calendar, chat and meetings.

Sovereign

Built and hosted in the EU, on-prem or Pure. No CLOUD Act. You decide where calendar, chat and files live.

See security

Collaboration

Meetings, chat, calendar and tasks in one interface. Microsoft 365, Exchange or Nextcloud keep running for as long as you need them.

Team and AI

The same AI for the whole team: context from calendar, chat and meetings — in the EU, on your models if you want.

Switch

Start with Microsoft. Land without it.

No big bang. Teams chats and channels stay usable — Liman becomes the EU surface beside them until you cut over.

  1. 01

    Teams stays

    Existing Microsoft Teams chats and channels keep running. Office on the desktop does not change.

  2. 02

    Liman beside it

    The same channels in an EU-hosted interface — meetings, chat and AI in one client, without breaking how people work.

  3. 03

    Cut over when you choose

    Move step by step to Matrix and your own backends when you are ready. No IT-forced deadline.
