How is OutreachBox Desktop different from Apollo.io?
OutreachBox Desktop is an app for Mac, with Windows and Linux in beta, that runs 20 role-based AI marketing and sales agents in a real browser signed in with your own accounts. Sends, posts, comments and connection requests pause for approval from the app or OutreachBox Mobile. Apollo.io runs sending in its cloud and offers a Chrome extension for prospecting; it does not advertise a desktop app. The desktop app is included on the Growth, Scale and Enterprise plans.
