About ThreadBridge

ThreadBridge exists because two companies that need to work together every day shouldn't have to agree on a chat app first.

The situation is familiar. Your team standardized on Slack years ago. Your biggest client is a Microsoft shop and always will be. So the work happens in email, or in a guest account nobody checks, or in one person's DMs that they copy-paste into a channel afterwards. The conversation gets slower and the details go missing.

The usual answers all ask someone to change. Guest accounts mean a second app to watch. Migrating means a project nobody asked for. Email is where a conversation goes to become a thread of quoted replies.

ThreadBridge takes the other route: leave both sides exactly where they are, and connect one channel to one channel. Everyone posts in the tool they already have open.

How we build it

A bridge is infrastructure, and infrastructure fails quietly. That shapes most of the decisions here. Each bridge runs as its own isolated set of processes, so one customer's expired token can't take down anyone else's relay. Every bridge is health checked continuously and restarted automatically when it drops. When it can't be recovered, someone is told, rather than the channel simply going quiet.

We're also conservative about scope. ThreadBridge asks for the narrowest permissions each platform offers, subscribes only to the channels you explicitly mapped, and doesn't store your message content. A relay that keeps a copy of two companies' conversations would be a liability for everyone involved, including us.

What it doesn't do

Edits, reactions, and file sharing aren't bridged. Threaded replies are: a reply lands in the matching thread on the other side. We'd rather say that plainly here than have you discover it in week three; the overview lists every boundary.
