The Problem Everyone Knows

Your agency lives in Slack

Your team knows Slack. Your workflows are built around it. Your integrations depend on it. Switching is not an option.

Enterprise clients live in Teams

Large clients standardized on Microsoft 365. Their IT won't approve Slack. Their employees won't adopt a second chat app.

Communication becomes chaos

Screenshots forwarded via email. Context lost across tools. Messages delayed for hours. Nobody knows where the conversation is.

SlackBridge Connects Both Sides

How it works

  • Slack channel → Teams channel: Your message in #client-acme appears in their "Agency Updates" channel
  • Teams channel → Slack channel: Their reply appears back in your Slack channel instantly
  • No app switching: Each side stays on their preferred platform
  • Multi-tenant: Connect your one Slack workspace to multiple client Teams tenants
  • Real-time: Messages delivered in seconds. No polling delays like Zapier or Power Automate

Built For These Scenarios

Agency + Enterprise Client

Your creative agency stays on Slack. Your Fortune 500 client stays on Teams. Project updates flow seamlessly between both.

Consultants + Multiple Clients

Connect your single Slack workspace to each client's Teams tenant. One inbox, many client relationships.

Vendor + Customer Support

Your support team uses Slack internally. Customers message you in Teams. No one changes their workflow.

Tool Transition Period

Company migrating from Slack to Teams? Bridge channels during the transition so teams can communicate across both.

Frequently Asked Questions

Can Slack and Teams chat with each other?

Yes. SlackBridge connects Slack channels to Microsoft Teams channels with two-way messaging. Messages sent in Slack appear in Teams, and replies from Teams appear back in Slack. Each side stays on their preferred platform.

Does SlackBridge support DMs or just channels?

SlackBridge currently bridges Slack channels to Teams channels. Direct messages (DMs) are not supported. Channel-based communication is the focus for team visibility and organized conversations.

Is messaging two-way or one-way?

Two-way bidirectional. Messages flow from Slack to Teams AND from Teams to Slack in real-time. Both sides can initiate and respond to conversations.

Does this work across different companies?

Yes. SlackBridge is designed for cross-company communication. Your agency can stay on Slack while each enterprise client stays on their own Microsoft Teams tenant. You can connect to multiple client Teams tenants from one Slack workspace.

Do my clients need to install anything?

No software installation required. Your client receives an invite link to authorize the connection. Once approved, their users just message normally in Teams. They do not need to know you are on Slack.

How is this different from Slack Connect?

Slack Connect requires both parties to use Slack. SlackBridge works when your client uses Microsoft Teams and will not adopt another tool. They stay in Teams, you stay in Slack.

What about Zapier or Power Automate?

Zapier and Power Automate rely on polling, which means delays of 3-15 minutes between messages. SlackBridge uses webhooks to deliver messages in seconds.
