Judo Marketplace can be used to provide card acceptance as well as automate fee collection for users. Judo Marketplace is thus good for businesses which connect customers with other businesses or sellers.

Peer-to-peer commerce - Where goods are sold between Buyers and Sellers directly, much like classified listings.
"Whitelabel apps" - Where a developer creates single mobile app but publishes this app multiple times with unique branding for each of their customers. If the developer also assumes responsibility for operating the application's infrastructure (web-servers etc) then we can describe this app as a marketplace app, with the developer's customers being the Sellers.
