Five Hundred Plus is an application that uses LinkedIn to help you make the most of your most valuable connections. You may have heard of "Customer relationship management" (CRM) applications used by companies to manage clients and leads. Five Hundred Plus is inspired by those tools but focuses on your own personal network, not your company's. Our main objective is to help you track when you were last in touch with someone and when you should get back in touch so they don't forget you.
