It is not a complete list of every product in the category, and you should confirm details with each vendor before you buy. Vendor details were checked on their own websites in November 2026.

TeamMate ChatBridge
ChatBridge connects Microsoft Teams with Slack, Zoom and Webex. Service providers can sell it under their own brand. It comes in two versions:
- Federated Chat stores nothing. It works with Zoom. File transfer isn't supported.
- Unified Connector App adds file sharing. Files are the only thing stored, and they sit in the customer's own Microsoft 365 SharePoint, never in TeamMate's cloud.
In both versions, messages are never saved. ChatBridge is SOC 2 Type 2 certified. It doesn't sync presence.
Good fit if: you need Teams to talk with Slack, Zoom or Webex; you're a service provider that wants a white-label service; or you want messages never stored.
Mio
According to Mio's website, Mio relays messages between Google Chat, Microsoft Teams and Slack. Mio discontinued its Zoom integration on October 31, 2026. Its pricing page lists per-user, per-month licences, only for users who need cross-platform chat, with a 1-year minimum and a flat $10,000 one-time implementation fee.
Good fit if: Google Chat is one of your platforms and you buy directly as an enterprise.
NextPlane OpenHub
According to NextPlane's website, OpenHub connects Microsoft Teams, Slack and Google Workspace, with a focus on Teams–Google Workspace messaging. NextPlane's site directs buyers to contact sales.
Good fit if: Teams–Google Workspace interoperability is your main need.
