Your company’s conversations, at your own address.

Gate one

Nothing to forget

Every query runs through a client that already knows which company is asking. Ordinary code cannot leave the filter out, because it never writes one.

Gate two

Enforced in Postgres

Row-level security applies to every statement, including the ad-hoc query written at 2am that never went near the data layer. It holds whatever the code does.

Proven, not promised

Tested on every change

A dedicated suite tries to read across the boundary from every angle — raw SQL, search, sockets — and blocks the build if any of it succeeds.

Channels & threads

Public rooms anyone can join, private ones that never appear to people outside them, and threads that keep the main view readable.

Direct messages

Private to the people in them. No role opens a conversation it is not part of — not Admin, not even the workspace Owner.

Calls & screen share

Calls start from any channel or conversation, and a call in a private channel is exactly as private as the channel. Media is carried in the EU and never recorded.

Search that respects access

Results only ever come from rooms you can already read, because search runs inside the same boundary as everything else.

Presence & read state

Typing indicators, unread counts and mention badges. DMs show when they have been read; channels do not publish who read what.

Audit from day one

Role changes, deletions and oversight reads are appended to a log the application cannot rewrite.

AI that respects access

Recaps, file summaries and a personal assistant that only ever use what you can already open. They write text for you; they cannot post or change anything.

Guests, safely

Invite a client or partner into the channels you choose. They see those channels and nothing else: no member list, no public rooms, no direct messages.

Built for IT

Single sign-on and automatic user provisioning, rules that stop card numbers and secret keys from being shared, sign-in and device controls, and set retention periods.

Connect your tools

Ready-made apps for GitHub, GitLab, Jira, Sentry and Linear, and a connector for any tool that can send a webhook.

Share a channel with another company

Work with a client or partner in a channel both companies can see. Each keeps its own copy and its own control of who can read it, and either side can stop at any time.
