Contact Marketplace in the sidebar (the page itself is titled Marketplace) is the global registry of contact and company identities across every team — the same person or business, even if added independently by multiple teams, resolves to one identity here.
Searching
Switch between the Contacts and Companies tabs, then filter by type and market. Toggle Shared only to show just identities belonging to a team that's opted into contact sharing. Each row shows the identity's name, its canonical types and markets, a closed-deal count, and a star rating with review count.
A Shared badge on a row means at least one team sharing that identity has opted into sharing it more broadly across the platform.
Drilling into a company
Select a company row to open a sheet listing every contact identity linked to it across all teams — contacts are linked automatically through each team's own contact-company associations, not something you set here.
