🔒 Siloed workspaces

Existing tools like Donut only match people within a single Slack workspace. Cross-org connections? Not an option.

🏢 Disconnected orgs

Companies with multiple brands, partners, or subsidiaries have no easy way to build relationships across teams.

🤷 Missed connections

Employees at adjacent organizations never meet the people just one workspace away who could become collaborators and friends.

CrossBrew is the only Slack app that matches people across workspaces.

Install CrossBrew in multiple Slack workspaces and it intelligently pairs people across org boundaries. Each person gets a DM in their own workspace with their match's info. No shared channels needed.


Our smart matching algorithm prioritizes cross-workspace connections, avoids repeat matches, and runs on autopilot so your community grows organically.

From install to first match, the whole process is frictionless.
