Use case
Internal Collaboration
Workspaces for projects and teams, with encrypted messaging, voice and video calls, polls and document sharing — built for firms that cannot afford leaks.
What it is
Workspaces for teams inside a regulated firm: messaging, HD calls, polls and document sharing, all end-to-end encrypted and hosted in Switzerland, with access that follows roles and projects instead of a single global inbox.
Why internal work belongs in Letro
Workspaces that mirror how you work
Create a Workspace per project, team or client group. Conversations, files and calls stay inside it.
Calls inside the channel
Voice and video calls run inside the Workspace, so a discussion and its record live in the same place.
Access that follows roles
Permissions are set per Workspace. When someone leaves or changes role, their access changes with them.
No more risky attachments
Share documents inside the encrypted Workspace instead of email attachments and consumer file-sharing tools.
How internal collaboration works in Letro
Set up once, then work as you normally would — just without the exposure.

Create a Workspace
One per project, desk or team. Add colleagues as verified Principals.
02
Talk, call, decide
Message, run voice and video calls and create polls without leaving the Workspace.
03
Share documents where they belong
Files are shared inside the Workspace and stay within its permissions.
04
Keep the trail
Internal approvals and document exchanges are timestamped in the audit chain.
